Beginner´s concern: loose part in Omega ?
Harald Reinholdt
I am a beginner in mechanical watches, so i hope this question isn´t too
ridiculous:
Since a few weeks i own a DeVille Prestige Chronometer with the Omega 1120
movement. The watch works very well but i have a slight concern:
When i hold the watch display vertical / crown right and shake it a little
back and forth there seems a little "play" in the direction of the rotor´s
axle. Of course i don´t mean the somehow metallic scratchy sound of the
rotor, when rotating in it´s meant (horizontal) direction. It seems, that
some parts whithin the watch are allowed to move 0,5 mm ?!
BTW: all the 3 of my (cheap) mechanical automatic Swatches show a similar
behaviour. I thought this beeing normal because of the plastic body of this
watches.
But as far my Omega is concerned: is this a normal thing in watchmaking and
has something to do with the ability of the movement / the metallic parts to
compensate different temperatures ?
Any hints that could dissipate my concerns welcome :-)
Thank you

partly as it would require design effort to remove the free play (ball
bearing joints are naturally "floppy") and partly because the free play is
beneficial in that it helps to absorb shocks - think of the difference
between a flexible tree that waves in the wind vs. a rigid pole that will
just snap when subjected to force.
All the Swatch group watches that are ETA based including your Omega (which
is derived from the ETA 2892) have similar autowinding systems and exihibit
similar free play. If they are autowinding on your wrist, there is nothing
wrong with them.
This has nothing to do with expansion and contraction as a result of change
in temperature. Although temperature stablity of the balance and hairspring
was (until the invention of Invar and other temperature stable alloys) a big
issue, it has no meaningful effect on the autowinding system.

makes sense to me. Please don“t be angry that i posted a similar question in
the omega-brand forum of www.timezone.com.
There the predominant opinion is, that there“s a loose clamp that holds the
movement in the body.
For example: http://forums.timezone.com/index.php?t=tree&goto=950545&rid=0
I think i am going to see my jeweller - his watchmaker respectively :-)
Thank you again.

Do we look like guys that would get angry with anyone ?

who answered you misunderstood what you were hearing/seeing. You should take
the watch to the jeweler just to put your mind at ease, but I'll be
extremely surprised if there is anything wrong with it.
Let us know either way.

I扉e been at my jeweler / watchmaker and to make it brief: yes, the metallic
clicking sound, when moving the watch (dial vertical / crown right) in the
direction "back and forth" comes from the ball bearing of the rotor. The
rotor of this movement is allowed to move a little in the direction of the
steel back. The watchmaker opened the watch and showed it to my, by gently
pushing the rotor near the ball bearing opposite the rotor mass. Then one
could see that the rotor isn愒 tight fixed in it愀 rotating plane.
The jeweler took three other watches off his shop window, that all have the
ETA 2892-2 derivated movements like my omega. They made similar sounds,
given the different masses of their cases.
So, everything is like it should be :-) Nevertheless an interesting
investigation

I know this is your new "baby" and it is natural to be concerned that you
got your money's worth and not a defective watch, but try to be more relaxed
about it in the future. I'm sure the jeweler was polite this time (more than
polite in taking the time to show you all those things), but if you keep
visiting him with "problems" that aren't real you will wear out your
welcome.

Yes, i really do. BTW: stainless steel, black dial and black leather strap.
I love that sound of the 4 Hz movement :-)

Fun story: when i bought the watch, 3 jewelers said, they won´t be able to
get the watch anymore, because Omega only wants to sell the Co-Axial
movements. "My" jeweler was told that there were "5 watches left" in
Switzerland. I can´t quite believe this. Anyone heard of sth. similar ?

Well, I was wandering through Geneva this afternoon, idly looking in the windows
of the jewellers (as one does) and I saw loads of Omegas. (I wasn't looking out
for Omega, but I am in the process of deciding whether I like the new
Constellations. I'm starting from a position of instinctively not liking the
heavy claws.)
I saw all sorts of co-ax and non-co-ax models. In fact, I saw 3 of the DeVille
automatics like yours (different dials, one was the black one) in a single
window.
So no, Switzerland hasn't run out of watches, or Omegas, or non-co-axial Omegas,
or even non-co-axial DeVilles. It's even a safe bet that there are more than 5
in any of the aforementioned sets.
