Hi, my name is Gijs. I'm 17 years old and from Amsterdam. A while ago my family found this Omega in the inheritance of my grandfather. We don't know anything about it. I googled a lot but couldn't find this specific model anywhere. Some look a like but the end links where the (unusual) bracelet is attached to seems very unique. On the back of the watch there's only very small engraved "14k" and "585". I'd like to show you the movement but i do not know how to open the back of watch. It's obviously a constellation but I'd like to know the exact year and why it's so hard to find it. Also I am curious of the bracelet. Can anyone help? Thank you!
Very nice, Calibre 751 C-case variant with integrated bracelet in 14k gold, cool watch and rather well kept. Don't wear it until it's serviced even if it's running it needs a full overhaul before wear or damage can be done to the movement by running it unlubricated
Do not think that is a cal 564. This is the one with day and date. Should be 751, as @dsio stated. The 564 is an earlier version, with date only. To OP: nice watch!
