Info needed, DIY cleaning watch movement
Terry
fluid or solvent (perhaps in an ultrasonic cleaner), followed by a rinse
containing some lubricant, thereby avoiding the need to strip down the
movement?
I am not a professional repairer and I don't have the know-how or
confidence required to strip down the movement of my watch, but I want to
have a go at cleaning it myself. Any info or advice would be greatly
appreciated.
I bought the watch (Rolex GMT) new in 1980 and have worn it virtually every
day since. I know you're supposed to have a watch cleaned and oiled every
few years but I just have neglected to get this done, mostly due to the
fact that I was quoted 6 weeks or so to do it, plus the cost (equiv.$400 or
250 quid).

Not recommended... at all.... ever.... don't do it.... costly... high
risk... quit now while you're ahead... I make money off moves like this...
So what's the watch worth? I think your quotes are high but the value of
the machine is likely high. You are likely to make mistakes that will be
more costly than the price of repair. I have not seen a first time attempt
do anything but harm.
What were the details of the repair quote you received? The price
seems high for general service but maybe others can shed some light on
this..
Through the whole of my first year of formal training we never once
touched a watch. Hairsprings...yes... many... ;^)
Please don't turn an "oil change" into a "junk yard special".
Yes there are production shops that do a minimal stripping down of the
movement but the dial and hands have to come off. The ultrasonic cleaning
will in my opinion (NSH "no so humble") no do a good job of cleaning and
lubricating. I grew up in a produciton shop and did thousands with this
method through my teens....
What's a gallon of Ultrasonic lub worth these days boys?
If you can't afford to have it serviced properly please set it aside
until such time as you can treat it to a proper cleaning.
Is there rust/moisture questions that would tempt you to be in a
rush to do this or is your curiosity getting the better of you? If it's
curiosity I'm quite certain that there are many of us willing to cough up a
"beater" for you to practise on. At least I am. You likely have a factory
fresh machine willing and able to work for you and your kin for generations
to come and with a few simple/easy mistakes you can render it worthless.
Please price out a new one before venturing forth into your Rolex.. by the
way ... where did you get the wrench to get into it?
Hope this helps.. Ian.

Hi, I'm a newbie to the group, currently doing the beginner's watchmaking
course on timezone.com, and after working on a movement for the first time, I'd
definitely advise against making an automatic Rolex with additional
complications the first watch you work on. Very easy to make mistakes; and
given Rolex's current service policy they could easily be extremely expensive
mistakes. You certainly could learn to work on your own watches- people do
every day- but if you learn something about what's actually involved in
properly servicing a decent mechanical watch you'll probably balk less at
paying someone a living wage to do it. I'm not at all sure exactly what Rolex
does, but a decent servicing could easily include a complete
disassembly/reassembly, cleaning and re-oiling of all bearing services, timing
and adjusting, etc. all of which is highly skilled labor. Many of us when
purchasing a high end mechanical don't take into account the cost of
maintaining a good mechanical- and then there's the fact that Rolex tries,
afaik, to make as much as they can on service. Getting "genuine" Rolex parts
and tools involves jumping through a lot of hoops for watchmakers.
Don't get me wrong, servicing your own watches can be great fun. Just don't
start with a watch you have a lot invested in financially or emotionally. :-)

It needs doing "soon"! A few weeks ago, a small ammount of moisture got
inside the watch by accident- I was washing my hands with the crown not
screwed fully down. I later noticed condensation formed on the inside
surface of the crystal.
Also, I am worried about some luminous paint that got in! This happened
some time ago, after having a new crystal fitted whilst on a trip to
England- a few days after I got my watch back, the luminous paint dropped
out of the end of the 24 hour hand!
By this time I was back in France where I live, and I could not take the
watch back to get it done, so I decided to try it myself. I had no trouble
removing the crystal and getting out the broken bits of luminous paint
etc., but I'd noticed a flake of the paint had stuck flat in date aperture,
and by now had disappeared into the movement! This is causing the hour hand
to "stick": Every day when the time gets to approx 7.40 p.m. the hour hand
would stop but the minute hand would carry on. (it doesn't happen at 7.40
a.m. , just 7.40 p.m.)
For a "wrench", I used a 6 ins. length of steel rod.
Using "5 minute epoxy", I glued the back of the watch to the middle of the
steel rod. I made a support for the watch by wrapping it in a couple of
layers of cling film and pushing it into a fist-sized blob of polyester
car repair filler, thereby forming a rolex-shaped cavity.
Using the rod as a wrench, I unscrewed the back a little bit and then I
prised the glue off the watch back before it had time to cure too much,
leaving it unmarked.
The main reason I took the back off was to let any moisture dry out.
I decided to take out the movement, and I worked out how to release the
stem and then found the two screws that hold the movement to the case.
I now want to take off the dial to see if I can find out what is causing
the hour hand to stick. I have had no problem taking off the hands as I
made a little tool for the job, using some sheet brass which I rolled down.
Unfortunately, I can't see how to get the dial off, so if Ian or anyone
else is familiar with this, I would be grateful if you could let me know...

you know, it always amazes me that when someone want to "play" with
something they have no knowledge of, that they pick the most expensive
item they can get their hands on
first up you are an idiot, no question
do you have ANY idea what that watch is worth, I don't give a stuff what
you paid for it way back whenever, its replacement value today
way back when I was still an apprentice in the 70s, GMT masters were
retailing for $1400 Australian, I could and did buy a brand new VW
superbeetle for $2800 on the road!.
and now with no correct tools, no skill, no training, no fucking idea you
want to take a complex delicate automatic date watch movement apart to
"Fix", that I would not let an apprentice anywhere near until their 4th
year.
again you are an idiot, put the watch away if you don't want to spend
money on it, because you only end up destroying it, and go buy your self a
cheap $50 quartz.

With respect, I don't think you should presume what level of skill someone
has (or what tools). You'll agree, I'm sure, that lack of information or
data does not necesarily mean lack of skill.
Anyway, thanks for your reply and thanks for trying to save me from myself!

if you really want to do this properly, dont start with that watch, pick
something cheap and simple, an old pocket watch say, and not a high grade
one either, then you can move on to a wrist watch, plenty of cheap 70s
mechanical and automatics around, ST96, ST69, Etas, practice on some of
those cheap metal quartz movements, not as complex but will still give a
feeling for handling the train wheels etc.
when you can be sure you can pull a movement apart, remove endstone
jewels, remove and replace the mainspring, clean the movement dismantled,
reassemble and oil it properly, know how to adjust it and have it all
working properly, if the case is water resistant, do you have the pressure
tester to check that?
here in Sydney the watchmaking school offer courses to people outside the
trade, there is about 8 going through now, they consist of retired people,
hobbyists and collectors, they are just learning enough to be able to do
their own watches and understand how they work
there maybe something similar in your area
do all that before doing anything to that Rolex,
your main problem with Rolex is that if you break anything or need a part,
its going to be hard for you to get them, Rolex will not supply you, watch
parts suppliers won't or can't help because rolex won't supply them
that $400 quote, what did they tell you that needed doing to it?
overhaul(full service), new plexi/crystal, back gasket, crown and case
pendant, pressure test -------- what else?

anybody can service cars, videos and clocks if shown how to in the first
place, watch repair is a bit like fine surgery, its not something you can
hack straight into, it takes time and lots of practice to develop the
skills to service watches, to be able to completely strip down and
reasemble a watch without leaving marks, burred screws, mark/scratches on
the dial/hands, one fingerprint left on a steel part will cause that part
to rust.
the little knowledge and skill you have at the moment is dangerous to
your watch, ok

I really don't think much else needs to be said about that. However,
there are a few other points I'd like to briefly touch upon. So, moving
right along...
On Condemnation:
"We cannot change anything until we accept it. Condemnation does not
liberate, it oppresses."
- C. G. Jung
from 'Psychological Reflections'
(you may want to think about that one a bit before moving on)

On Understanding:
"Anger and intolerance are the twin enemies of correct understanding."
- Mahatma Gandhi (1869-1948)
"A child of five would understand this. Send somebody to fetch a child
of five."
- Groucho Marx (1890-1977)

"Creative minds have always been known to survive any kind of bad training."
- Anna Freud
"Creativity involves breaking out of established patterns in order to
look at things in a different way."

will accomplish with all the tools in a machine shop."
- Robert Hughes (1938-)

dAz, I hate to say it but, not only are you the idiot, it's idiots like
you that make these boards useless. Suggestion: You should attempt to
acquire, at your earliest convenience - A) A clue, B) A grip, and C) A
life. Good luck.
Here's one last thought for you. I'm not sure who said it first but it
just seemed to appropriate to omit.
"Better to remain silent and be thought a fool, than to open your mouth
and remove all doubt."
Terry,
Keep up the good work, mate! Many of my watches over the years have
had their monetary value far outweighed by their educational value,
which only you can ultimately decide. The time is only the first of many
things you can learn from a watch. However, I will say that I "bought" a
few less expensive lessons before attempting the more advanced and
sometimes costly "courses".
Anyway, here's one for you.
"Any intelligent fool can make things bigger, more complex, and more
violent. It takes a touch of genius--and a lot of courage--to move in
the opposite direction."

Remove the dial with a razor blade, find the dial edge close to
mainspring barrel, so you won't accidently damage other parts, dial is
snape tight to the movement on this model.
After you manage the dial, do not turn the movement up-side down, for
some parts are not secured to the movement. Carefully remove the date
disc (date indicator) by turning one hold-screw (three holders only
one is screw) to the side, and you are ready for the soaking. I
called it soaking because you don't have any cleaning device, nor you
have the knowlege to do the manual cleaning, but you do have gut and
brain so I willing to guide you from here.
Go get some mineral spirit and a good set of proffesional tweezer and
screwdrivers. When those are ready, email me or post here, I will
tell you what to do next.
Good luck.

hammer instead of torturing slowly it with razor blades
it still going to end up the same, a stuffed watch, useful to no one
Terry
Thanks for your encouragement- it's decent of you to help me out, I've
decided to go ahead, although some people think it's madness! Maybe they
are right!
By the way, about the dial removal by prising with a razor blade- I don't
know if it's the same on the other GMT models,(my watch is a Rolex mod.
16750 GMT,the movement is 3075), but I have already removed the dial by
means of 2 screws which I found at the edge of the movement, (sort of at a
tangent to the circumference). I slackened them slightly and this allowed
the dial to be lifted off . Anyway, I have also taken off the date disc and
the little washer and wheels.
I was looking to see if I could find out what is causing the hour hand to
"stick", but unfortunately I couldn't see anything obvious.
I realise it is propably not a good idea to repeatedly take the hands off
and on, but I have reassembled the watch for the time being until I get the
cleaning stuff. I feel more "at home" with the job now, having manipulated
some of the parts successfully, even though I haven't dismantled anything
of any great complexity.
Could you Gao, or anyone on this group, give any opinion on the pros and
cons of cleaning and lubricating without a strip down vs. doing it the
"right" way i.e. fully stripping and cleaning then lubricating the various
parts? Bearing in mind that the watch is now almost 22 years old and worn
continuously since new. (now loses 15 secs/day).

Terry

Stop this madness! Get a piece of junk to work on, master the repair
of junk then start on slightly better watches. Terry, your ego seems to
involved here and is not allowing good sense to prevail. If you do not
care about breaking one of your good watches then consider that this watch
cannot be passed on to others. It may just become parts, if luck is
involved.

It's almost hard to believe, but it seems that not only have Rolex
bracelets always sucked, but they used to be even worse than they are
today! Why is it taking them so long to make solid, non-flimsy
bracelets?

use it to remove the hands before attempting to remove the dial! Then look
for screws around the edge of the movement that hold the dial feet. Some
older watches had
screws on the back of the plate. On these, the screw had an eccentric
shoulder with a knife edge. This engaged the post, and pulled the dial on
tight as they are gently backed out a bit. Save your razor blades for
shaving, and use the proper tools!

In respond to your need and review of your profession, I think you
have a ultrasonic cleaning unit, right? But yours probably too
powerful for a watch movement. Get some mineral spirit (or even
better Benzine), put in a beaker, half filled the ultrasonic unit with
water, put the beaker in, than you are set.
Make a brass wire to form a loop or hook with hanger on top, so you
can hang the movement half the way in the beaker by hook to the stem.
Yes the stem stay and all screws tighten before ultrason clean, and
clean for ONE minute only.
Dry the watch with paper towel follow with hair drier, keep hair drier
perpendicular to the back of the movement so you don't ruin the
hairspring, and keep a distance of at least 1 foot away, set low heat.
This will take a while (10 minutes or so) so make a device for it,
don't just hold it by hand.
Check to see if the movement are complete dry or you can wait till
next day. Now wind the watch and see if it works. The problem now is
to check and make sure your hair spring is true and clean from any
chemical or rusts, you may need some Acetone for this part. But
remember keep all chemicals away from dial and date disc.
I will be back tomorrow to guide you from here.
Do it now.

Hi Genway ,
O.K., Maybe I'll wait until I can get some Benzine. I'm not sure what
mineral spirit is - here in France it won't be called that. Maybe it's
"White spirit" (used for cleaning paint brushes or thinning paint)
I assume the idea is to dissolve the various old lubricants and other
soils, leaving as little residue as possible when the stuff has evaporated.
Or is the aim to leave a film of some sort to act as a lubricant?
You mention using acetone for the hairspring. Could you explain a bit
further? I'd prefer to know more before I decide what to use.
Also, can I use the heater on the Ultrasonic for this ? it normally runs at
60 degrees C. (140F.)

watch, you have a valuable high grade watch, I mean you are quibling over
a $400 repair to a $2000 watch, what happens when you take a Merc in for
major service?, you get a bill for $50?, I don't think so
the watch movement has to completely dismantled for cleaning, no
shortcuts, if you were to clean the movement by dunking in the ultrasonic,
the solution will force its way into the barrel and endstone jewels, and
no amount of rinsing or blow drying will remove it.
if you use a heated solution you will affect the shelac used in the
escapement
make sure its benzine not "benzene" benzine is white spirit/shelite, its
petrol without any additives, its used in lighters and Colman pressure
lamps and stoves made for the purpose.
"Benzene" is a poison, don't use it
BTW dont use the shelite/white spirit in the ultrasonic, even in a beaker,
the risk of explosion is to too great.
do not use acetone anywere near a watch movement, again the same problem of
disolving the shelac used in holding the escapment jewels
after cleaning the movement properly there should be no thin film of
anything left behind, the movement will need to be lubricated with the
correct watch oils and/or grease.
the impression I get from you that you are pissed off with the $400 quote,
in that case you should take the watch to someone else and a second
opinon, you are not interested in doing watch repairs, you just want this
one going, in that case you should just get rid of the watch, sell it to a
dealer in wrist watches and use the money to buy yourself a new watch
in everything you have said and your approach and attitude to this shows
you have no idea what you are doing and dont really care either.

"Should"? "Should" is a dangerous word, my friend. Don't get me
wrong, Darrell, I thoroughly understand what you're trying to say.
However, the last time somebody told me what I "should" do, I offered
them a few "suggestions"....
As for value, it's all about perception. Period.

Ahhhh, the Authority On All That Is Useless has spoken again!
Now dAz, you're obviously an intelligent person and while I will
reluctantly admit to agreeing with some of the things you've written,
it must be clear to you of all people that the vast majority of
amusement isn't coming at anyone's expense but your own.
People, the only thing Terry "should" do is whatever he sees fit to
do. Who's bloody watch is it, anyway? If he thinks the watch is worth
it, more power to him. If you have such genuine concern for the watch,
dAz, why don't you offer to fix it for him? Or did you not make it past
the first year?
If nothing else, Terry will have a degree of education based entirely
upon empirical knowledge. While that might seem insignificant to you,
and I can see where it might, it's something far more valuable than
anything contained in the insidious spate of miasma you spew forth under
the guise of advice. And I mean that purely in the pejorative sense.
FWIW, I participate in news groups as a means of exchanging
information and ideas on specific topics. Not, as some seem to believe,
to subject myself to mindless, vulgar outbursts of condemnation and
ridicule. Let alone write about it.
And my guess would have to be that Scott wasn't into it, either.
So, dAz, here are some suggestions you may want to try before writing
your next post. Seriously, man. I'm worried about you. OK?
1) TAKE THREE (ok, more like thirty) DEEP BREATHS before you even
start typing. Better yet, do it every ten minutes. Or five. It couldn't
hurt.
2) Get A LOT MORE BRAN in your diet (you may qualify for "Super Colon
Blow" therapy - ask your Dr. for details)
3) TRY PROZAC! Or pot, or Valium, or maybe that hammer... just do
*something* before you blow that gasket and get your miserable self all
over us....
That's all I have on the topic. Let us know how it works out, ok?
Sincerely,

It is the same thing.

Correct.

In some cases the left residue could be gummy, acetone will disolve
and break it to powder, so you can blow them out by hand blower,
remember this is household remedy, not a professional way.

Better not, heat could loosen up some of the jewels was hold by
shellac, or changed the physical property of some springs.

These products are combustible but are not highly volatile. They are also
somewhat oily.
White spirit is white gas, Coleman fuel, naphtha, cleaning fluid etc.
these products are highly volatile and combustible with a different vapor
pressure than mineral sprits.
Often naphtha is/was used as a rinse, 2nd and 3rd, in mechanical watch
cleaning machines. They are not recommended for use in any ultrasonic
cleaning machine because of the heat generated and excess vapor.
