Hi fellas. My mother in law handed me this after clearing out her late mothers estate recently. It was her grandfather’s. Confused? Yeah, let’s get to the point:

Seamaster automatic. Gold plated. Looks like the original lume in hands. Plexi crystal, scratches. Bought late 50s or early 60s, worn till mid 70s. Likely never serviced but runs in dial up position. Not opened to check movement as I don’t have the tool.

Anyone who can give me the ref number? Is it even legit? If so, does it look original?
Thanks!

Opening the back will not only let you examine the condition of the movement, but the reference will be stamped into the case back itself.

 

It's a full-rotor Seamaster ref 2846/2848 from the mid to late fifties. If you're in the US, it's most likely to house a cal. 500.
Are the damages seen in the straight-on photo on the dial or the crystal?

 

Hard to tell from these pics if that crust is on the crystal or the dial. If the crust is on the crystal, I'd say you have a winner Likely a 1950s "hooked top coat hanger S" Seamaster. If you want to wear it, take it straight to a watchmaker who deals with vintage watches, and ask them to evaluate the watch for you.

 

Thanks a bunch gents. The damage is solely on the crystal as seen here (I hope):



There’s only a single small black blemish on the dial next to the O in Omega.

 

Looks like the crystal, if you look at the damage over the hands.

 

Yep I concur with the ID of a 2846 (the 2848 is the sub second version but both numbers are listed in the inner caseback as it was used for both). Obviously a gold cap version. I think the crud is on the crystal, that should clean up very nicely. That looks slightly later than some inc mine. If I were a betting man I would put at 1958-9 with a serial of circa 16m.

 

Nice jeans.

 

Hahah, I see my ninja reflexes are insufficient for the omega samurais in here. Yeah, it’s another time- and money consuming hobby of mine...

 

So I found a watch knife and opened the watch. @padders was right on the money - serial is 1646xxxx!

Movement looks good to my untrained eye, but needs some grease:

 

Movement looks clean! Give it a service and it will be a great piece to wear.

 

Well, I think it cleaned up nicely!

Thanks for all the replies here, I’ll bring it to a watchmaker. After that I’ll try to convince my brothers in law to wear this beautiful heirloom instead of selling it...

 

Very nice seamaster.
Keep it good.

 

Welp, the crown was apparantly in bad shape, it broke when I was putting a strap on the watch

It was pretty worn down anyway, but can anyone tell me which is the correct crown for a 2846-7sc?

On eBay I found this, which seems to be the one currently on the watch (although worn down so the gold is gone from the outer part):
