Omega Seamaster 2848 Cal. 491

Hi all,

I have inherited an old Omega Seamaster 2848 Cal. 491. Although I have found some forum threads with similar versions, I have not found the exact match - and wondered what you guys could tell me about the watch and its potential value.

The watch is in pretty bad condition and has not been in use for decades. I am considering having it repaired, but an omega repair/service is quite expensive (500 to 800 EUR, maybe more considering its condition) in Norway.

Thus, I turn to you for advice on the following:
1) What can you tell me about the watch model?
2) What is an estimated value? Is it above the cost of repair?
3) If repaired, how often would it need service?
4) The front seems to be of plexi glass - is this common for the model series?
a. If this is plexi glass - this makes the front polishable. Is this pretty straight forward and something that I can do? Or should this be left to the service guy?
5) Some information to the service guy; e.g. what NOT to change to preserve its value.
a. The dial - even with some corrosion?
b. Change the plexi to sapphire?

Some information on the watch:
Black dial - looks to be some corrosion on the inside
Subdial
Outer caseback features the words “Seamaster” and “Waterproof”
Lug width ca. 18 mm, Dial width: ca. 34mm.
19 Jewels
The inside of the caseback seems to indicate the following: 2846 7 SC 2848 (I got the watch opened at the watchmakers, so the photo is quite bad)

Thanks!

Yes. That's already been improved enough.

Thanks for the reply, this helped a lot!
The essence; its worth having it fixed and will look for an non-omega service guy 😀

Hopefully, they will have the necessary parts.

Any thoughts about changing the Plexiglass front to crystal?

Fair market value for an unpolished, fully intact black 2848 would be > $1000 US, in my opinion.

Nice example! You're most fortunate.
