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.

 

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.

 

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