Help identify and refurb suggestions - sentimental

I'm new to this forum, but somewhat active on some other watch forums. My father and I were moving some documents recently and stumbled across my grandfather's Omega from the early 70's. He'd forgotten it was there and it was pretty tarnished. We put a little polish on it, but unfortunately, the plating is awfully thin on the bracelet. The case is in pretty good shape and the movement appears to be just fine. I'm curious if anyone can help identify it. I think it's part of the Geneve line, but most of the others seem to say "Geneve" on the dial. I'm also curious for suggestions on refurbishing. I was thinking to put it on a strap and let the bracelet be, but finding a strap to fit due to how the lugs work is problematic. I'm not sure about having it re-plated. Any suggestions would be great, thanks.

The reference number is on the inside of the case back: 166.074

I'm seeing with how the pictures posted that the details on the caseback and movement are hard to read. The case back has 1660174 stamped and 3660833 engraved. It also says LUNETTE, PLAQUE or 20 MICRONS, FOND ANCIER INOXYDABLE. The movement says Unadjusted 17 jewels Omega 35552487 Swiss 1020.

Thanks for the quick feedback on identification. Per the Omega website, that reference should have a 1022 caliber and not the 1020. It should also be stainless steel. Are vintage details on the Omega website very reliable or can be a bit ambiguous. In my experience other manufacturers can be a little hit or miss on their historical details going back that far.

The Omega vintage site can be a bit ambiguous at times.

As for going back "that far"... we frequently research back to the 40s or 30s. The 70s are nothing compared to that.

Since this is not a watch collectors howl at the moon for, they won't give you crap for sending it to Omega for evaluation. Don't know where you are, but if you can send it directly to Switzerland, that would be best. They will tell you how much it costs to restore as new, if that is your choice. You might choose something less interventional and more local. All up to you; it's your money to spend how you like.

I'm on the gulf coast of Mississippi so Switzerland isn't nearby, but I'm not familiar with anyone else to send it to so I'm leaning that direction.

The bracelet Doesnt seem to be too bad to me - difficult to really tell with those photos though, and it seems to fit you

I’d be tempted to just wear it as is for a while. If you really cant live with the bracelet condition, then get it replated locally if possible

Unless this is incredibly sentimental, or it will become an heirloom piece and be handed down, I wouldnt send this to Omega ( as they are likely to be very expensive Vs “value” of the watch)

its your watch though

best of luck
