Doubts with Omega Cal. 352 Chronometer Jumbo Seamaster

Bobbafett · Sep 13, 2019

Hi, my friends, I come to omega forums to look for some answers.
Some years ago I bought this Omega Seamaster chronometer 352 cal. I thought that it was a Franken watch but I have some doubts now.
First, the model number is 2657- 1 / 2494 without SC mark. I think that this kind of model (center hand second) must have the SC mark, but I have found some examples that don´t have this marker.
Second, I can´t find the same dial (mine with horrible redial) in other omega watches until recently, I spotted a similar dial with a jumbo case and a chronometer movement too.

Do you think that the only thing that this watch need is a new dial or is a totally Franken watch?
P.D. If anyone has a spare dial similar to this one, please, contact me.

Kind regards.

Cal. 352 came in that case - whether this particular movement with that serial was born in omega in that case only an extract can clarify. Your watch in addition to having a poorly done redial also has a movement in poor shape. And finding a correct original dial in good shape will be exceedingly difficult.

Omega says that CK 2494 is Caliber 351 or 354, which is a COSC chronometer movement.

Assuming this is correct, you have reason to doubt.

I'd believe MSNWatch over anything the Omega website says.

and the cal 354 can be COSC, the vast majority were not.

Those entries are incomplete - if you look under case ref. 2577 you will see the same 351/354 movement designation and there are many legit cal. 352 movements leaving the factory in 2577 cases. Cal. 352 is correct for this case reference. It is an uncommon case reference - @Bill Sohne once commented there is maybe 1 2494 for every 100 2577s and even more uncommon housing a cal. 352 movement but these are legit.

Like I said, "assuming". You guys who have done a lot of research certainly have my respect.
