Is this the correct movement? Is this a 341? Is it not suppose to have a 343 in it since it is a chronmetre? Any thing else I should know? Just got the watch last month. First photo with a real camera so sorry about the rough photos.
Can you take some pictures of the caseback? Also, I do believe that these chronometre dialed watches were supposed to have all the "adjusted to ***" markings on the rotor for these bumper movements.
Date of serial looks ok but I too would have expected more adjustment text. Maybe the rotor has been swapped. Would a Chronometer have had a better regulator? It does look rather like the precursor to the 341 to me.
Isn’t this a centenary 2500 with 30.10 jub ? https://omegaforums.net/threads/omega-centenary-2500.16309/
Your right based on the size I think it suppose to be one of these. The watch is 35 mm. 30.1mm, sub second: 330 (30.10RA PC): - 331 (30.10RA PC AM): antimagnetic 332 (30.10T1 RA PC): redesign 331 333 (30.10T1 RA PC RG): excenter regulator
Here is the same watch with a movement not marked "Adjusted to..." http://www.vintagegoldwatches.com/p...-centenary-1944/#lightbox[productLightBox]/8/
