A 1953 Omega Automatic Chronometre - 18k Solid Gold - Serviced

Beautiful lugs on that 354, the 28.10's all had exposed springs, I believe.
Glwts.

The change over to the 3 digit movement naming was circa 1948, a 13m serial would deffo be a 35X rather than a 28.10 as it is well into the 1950s. As noted by UB, no exposed springs, not a 28.10 and it has 354 marked on it!

Whatever, beautiful condition watch and movement.

Hi @UncleBuck and @padders

I have to disagree with your statements ....
28.10 is part of the movement designation ....

The 354 is a 28.10 based movement it’s complete 28.10 naming convention is as follows

28.10 RA SC PC T2 RG AM 17 jewels ...
(And you now know why omega went to a 3 digit naming convention ..... ). It’s a mouthful .

As ref take a look below at the Omega Material list below ...



@Vanallard you did ok in my book !

Good hunting

Bill it’s got 354 stamped on it. Let’s call it 354.

Hi @padders

I still disagree with what you stated . The 354 is part of the 28.10 movement family . It a technicality correct id and omega cross-referenced documented it.

@Vanallard only referenced Marco Richon’s AJTT . It was fine for Marco to use 28.10 RA SC -354 .... it’s fine for me and is correct he did nothing wrong . You should at lest acknowledge that it is.

Yes, omega moved to the 3 digit naming convention for ease of use ... going forward ...

And yes it’s easier and less complicated to just say 354.

Ok??

Hi everyone...

This is someone’s sales post , and other members brought up what they thought was an error in a listing.
There is no error in the naming of the movement in the listing.
I was just casually scanning post and I just don’t want to propagate incorrect info.

That is all...

Another interesting piece of information recently shared by a fellow member. The
Poinçon de Maître (pictured - stamp with no. 28) on the inside of the caseback indicates that the case was manufactured by Patek Philippe in Geneva.
