Grandfather’s Seamaster Deville

My uncle passed a few years ago and his wife gave my mom her father’s Seamaster Deville, and my mom gave it to me. I don’t know much about the watch other than my grandfather most likely bought it in the 60’s. I have the original box and booklet. I don’t believe it has the original band. I wanted to see if anyone could pinpoint the year or model number. Also, what type of band did it originally have?

Possibly a 552 movement. Linen dial. Too bad about the marks on it. Bracelet not original. Could be a toughy to remove. Either leather strap or 7 link beads of rice bracelet (there is a 5 link, but for a different model and case design)

Do you believe it to be from the 60’s, or could it be earlier/later. My grandfather was born in 1903 and died in 1977, so it could easily been from the 50’s-70’s.

The case is in really nice condition. It's worth re-emphasing what SOG53 said, definitely get the watch serviced but don't let them polish it! Watchmakers are often itching to do this, but even a "light polish" is unnecessary and will spoil the original finish. That diagonal cross-hatch dial is a lovely, slightly less common variant and even if the marks are permanent I would just live with them and see them as part of the history of the watch.

These watches would originally have come on plain leather straps or Omega "beads of rice" bracelets - either would be authentic. I would just get a nice leather strap anmd maybe try to hunt out an original vintage Omega buckle. If properly serviced and with a high quality strap this watch should be able to be worn, look stunning and keep excellent time.
