I have an Omega PW in a gunmetal case. It came to me from a very reputable dealer in Europe. However, the dial and case have the Omega logo but there is nothing on the movement.

Did Omega do this? Could that info be under the dial or ...? Thanks.

Hi John

The movement could be marked on the dial side.
If the dial is removed take a picture so we can check the setting mechanism.
Please post the serial# on the case.

I think Omega started putting serial number on the bridge side around 1912. It can be dated by the case number to give an idea.
