Accuracy 7s26
Pippo
I would buy a seiko5 automatic - movement 7S26; you could tell me the
accuracy day?
Thank!

Specified nominal accuracy is not impressive. However 7S26 may be regulated
to be much more accurate.
Just Google "7S26 accuracy" and you will get common sense on accuracy of
this movement.
Enjoy this very reliable workhorse movement.

How much regulation?
The following link (are just interested to the "Monster") explains:
[begin]
All 7S26 movements tend to run fast when new (3-15 seconds fast per
day, varies from watch to watch), but they need time to settle in ,
don't judge a 7S26 movement's accuracy until it's had about a month or
two of active use, give it time to settle in, if it's still running
fast or slow, it *can* be regulated by a competent jeweler
[end]
What are your experiences with the 7S26? ;-)
The "Orient" are more accurate?
Thanks!

As far as I know 7S26 movements leave factory as to fast. So if the watch is
too much fast for you, it can be slowed down

There is a theory (per analogiam to car engines) that there is a break-in
period ca. 1 month after which movement stabilizes it's run. I'm not an
enthusiast of this theory.
Movement may be regulated by every watchmaker with timing machine. It's very
simple and basic operation on new movement and may be done in several
minutes. Would be much better if you inform watchmaker how fast/slow is your
watch per day.

I'm not a watchmaker and have no knowledge whether Orient movements of
comparable price to 7S26 have bidirectional winding and whether they have
hacking second and possibility of manual winding.
Maybe other fellows will join discussion.
IMHO they are comparable. I would choose Seiko.
Have no experiences with 7S26, however have a watch with Seiko 7009 movement
(7S26 predecestor, very similar with magic lever).
It was fast too much. Regulated it myself without timing machine. It gains
now only 5 s/day and is stable. Won't try to improve this result without
timing machine.

How much money can ask a watchmaker to calibrate 7s26?

ca. 6 USD in Poland I hope. However there are watchmakers here at
alt.horology.
I'm sure they will answer your question soon.

automatics are generally rated a bit fast, it helps to compensate for
the daily knocks and bump the watch gets while being worn.
and it is better for a watch to be fast rather than slow.

there is actually, the watch needs to settle in when new, specially if
it has been sitting in a display case for a while, and each wearer is
different in day to day habits and motions.
wear the watch for a month or so, then set it against an known accurate
clock or time standard and then only refer with that one standard or
clock, wear the watch for 10-14 days without resetting the time, then
read the time difference divided by the number of days worn will give
you an average daily rate fast or slow.
eg; if the watch is doing an average 22 fast per day, then go to the
watchmaker and ask them to slow the watch by 22 seconds.
so if the watch in question is showing an instantaneous rate of
25seconds fast, and slowing it 22secs will make it 3 seconds fast per
day, but because we are working on average daily rates the actual
timekeeping should be close to time for that person.

Orient is part of the Seiko group but AFAIK is a stand alone factory,
their movements are based on older style Seikos because they buy the
older seiko machines and dies, but there is nothing wrong with that,
they do make some nice watches.

nothing to a couple of $$, however if the watch is a water resistant
model, and you do intend to wear it in the water then it will have to be
tested and they will probably charge for that.
if you buy the watch from a store then the regulation is part of the
warrantee, so the regulation and pressure test should be covered with no
cost to you.
buy the watch on eBay then the seller only has to cover if the watch is
DOA or faulty, getting the watch regulated and/or pressure tested is up
to you.
hint; most stores don't have a watchmaker on staff, this may or not be
the case where you live.
if that is the case then the watch has to be sent out from the store and
will take any number of days to do.
best to find a watchmaker who is experienced in mechanical watches and
has both a timing machine and a pressure tester, if the pressure tester
is the waterless type then he/she could do the watch while you wait.

In Italian and English forum I read that the "Orient - Mako" has an
daily accuracy (approximately): (+5 ; +10) sec..
What do you think?
dAz
well that sounds like the tolerances from the factory, but there is no
reason it won't maintain 2-3 secs per day, my cheap seiko does,
like any mechanical watch you will to adjust the time on occasions, none
will compare to a quartz for timekeeping, but on the plus side, no
batteries needed.
once regulated you will probably only need to adjust the time every week
or two, I have given or sold quite a few Seikos to friends of mine for
general use, they all find the watches reliable and good timekeepers.
the Mako is a nice looking watch and at a good price, it uses an older
style Seiko movement, looks like it is based on a 6000 series which
Seiko no longer make.
here is a comparison of a Mako auto to an ETA2892a
http://www.youtube.com/watch?v=lgwTnAlX2LU
mind you the ETA movement alone cost more than the complete Orient watch :)

What margins of accuracy must overcome to be valid the warranty clock
so as to be able to adjust without charge?

Depends on manufacturers specification of the watch. If the watch's accuracy
is outside specification it should be regulated without charge.
Unfortunately I can't find official accuracy specification of 7S26 movement.

Ciao Pippo. Old version is 7s26a, make sure you get the new 7s26b. I have
both, new version has better precision.
But who cares about precision? You are not buying a mechanical for
precision, if you want it get a Casio or Junghans radiocontrolled.
And ten seconds a day is more than enough for a human being.
You are buying a mechanical because you like it, the same way you like a
fountain pen or a wool beret or Chinotto Lurisia instead of a coke.

I was interested in purchasing the following "Seiko Monster":
.. but not 'specified if the version of the movement is "a" or "b" and
for what I've read it seems that it can also have a gap of about twenty
seconds (one day) ... the "Orient - Big Mako" seems to be more
'accurate.

Seems? You will only know when you have it. Every single movement is
different from another.
I have a Seiko 20 seconds fast a day and another one 20 seconds a month.
Get what you really need or like: you can get the movement regulated
later.
If you do not need or like the watch, you will not wear it, despite the
precision.

I do not try the accuracy of a quartz!
... I have many automatic (although not an expert in automatic watches)
watches (accuracy: +10 sec.), I would settle for an accuracy of 10 sec.

Ahhh haaah ! Well, i'd just buy the watch i like, take the back off,
service and regulate it to within 5 seconds(or better if i really put
some effort into it).
But then.. i'm just a dumb Antipodean.. ;-)
>(And on the Seiko Monster you simply cannot read through iron)

The 'B' has a much better balance setup offering far easier
regulation. I believe the material and size of the balance has been
changed too. Whether one is more accurate than the other though, i'm
not so sure about. It may just be that one requires more effort.
Let's not forget, even a BFG866 could be regulated within 10-15
seconds with little trouble. In trade school we had various calibers
running at rates that in the real world of service and repairs would
be downright silly to shoot for. None the less it could be done, just
took some doing.

speaking of ETA, came across this on eBay

65 eta805.114 movements for parts.
parts? what parts?, the one and only screw holds the stem, everything
else is welded together, about the only use I can see for these is to
set them in plastic for a coffee table top :)
