Need help to identify an old Omega Seamaster Automatic

Hi folks,

I found and bought an old Omega Seamaster Automatic watch.
It wasn't a flea market find, but it also was not for big money.
I only saw some bad pics and did not find exactly the same model in the www.
That is always a bad sign regarding all the watches with redials and other problems.
But, as I mentioned above, it was not big money and the watch was working!

The dial is signed with "Omega automatic" and Seamater above.
The dial has kind of patina, but I know, that there are old redials on the market.
The hands are kind of simple and kind of short??!
The back is signed with waterproof and Seamaster.
The case is the known beefy lugs case.
The crown is signed with the Omega logo.
Crystal should be wrong (?) with the step on the outside.

So, what do I have here?

Thanks in advance and now some pics:

Best,

Looks like a CK2577, probably with a Cal.351.

Someone else can surely confirm/correct me though!

My guess is this one:

Your watch looks to be in very nice condition. A trip to a watchmaker should solve all mysteries.

Depending upon what you paid (and you say it wasn’t much) you have a nice 1950-1953 bumper watch in good shape.

It probably needs a service but you can get the watchmaker to photograph the movement (the movement serial number will help date the watch) and the case back.

You can ask the watchmaker to source and fit a new seconds hand

Nice watch. My guess is a reference 2846, caliber 501 from roughly the late 50s. Can’t be a 2577 as those had screw down casebacks.

Yes, 2846 ref from 1955-1957. Uncommon non-luminous dial variant. Nice, original condition.

The solution of the puzzle:

It is an Omega Seamaster automatic Ref. 2846-1SC with a nice Omega 501 movement.
It seems to be a very early one of this reference.
The movement number (14.58 mio) dates it around 1955.
Wrong crystal (will get a correct one) and second hand has lost the end.
Otherwise it seems to be in good condition.

Looks very nice, you will need to address the rotor rub.

Yeah, watchmaker told me same!
But he is a certified watchmaker, he should fix little problems.
Think, a service will fix it.....

It’s a stunner. 2646/2648 are my main focus and it’s just beautiful. Congrats.
