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

    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 ...

    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??

    Bill

    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...

    Bill

    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.
