Help ID a Watch Please - Seamaster 165.002? Copy?

Hi!

I was given this watch that was my grandfathers. Not "left" to me, just something that was in his belongings that the family thought i might like to hang onto after he passed. He wore it for as long as i can remember, every day including when gardening (which was a lot of gardening). I did ask him about it when i was younger (30 years ago it'd think) and he said he wasn't even sure if it was a copy or not as it was a gift from someone after they returned from a trip overseas. The strap is just a spare i had which i put on because the one that was on it was very worn.

It looks like a 165.002 in images on google, but they all seem to have a cast logo on the caseback and not etched like this one. It has a sweeping second hand, but the second hand does not stop when setting the time (if that helps).

I'm not really concerned if it's fake or in poor condition, it's had a lot of wear and still running and it's just a memento not an heirloom. I'm not planning on selling it or anything. If anyone has any thoughts on make/model/fake/real it be curious to know.

Thanks

You need to get the case back open to see inside. It’s fairly easy but you could also ask a local watchmaker to pop it open

Everything looks good to me and it certainly isn't a copy. The only negative is the water damage on the dial, as if the crystal got steamed up and it dripped off between the 4 and 5 markers. You can't fix that but it's not a massively big deal and it's worth having the watch serviced, though be aware that to be done properly will cost around £100-150. I wouldn't keep that strap on it as they are not good for case backs.

Thanks for the tips. It's definitely automatic. I did give the crystal a light polish, but it didn't make much difference. I did go very gently though. I was concerned about rubbing the case. I'll mask up the case and have another go, or there is an official omega service guy somewhere around here (Perth Australia)
