The 1345 refers to the caliber of the movement, and has nothing to do with the reference of the watch. You’ll need to have the case back removed to access the actual model number of the watch which would be stamped inside the case back. Only then will you have a place to start your hunt. The caliber 1345 Omega quartz movement pictured was used in countless references, about 40 years ago.
Thank you, I also found this reference but it‘s not quite the same. Mind the the case which is obviously built for this bracelet. Hope to get the watch next week.
The bezels and bracelets are different, yours is similar to the "Marine" 1332, but the cases seem identical and recall earlier designs from the 70s that first appeared with Cal. 1301.
Well, 1345 cal was only a guess, maybe it contains a 1332 or a 1337 which would be great. It would be a spare movement for my Nimitz, if that one needs it in future days.
That picture shows what has to be the correct bracelet (looks like other period bracelets) and the one on yours was recycled from the 133x Marine model, and yes it's a nice bracelet, a successor to the chunky bar bracelet from the early and mid seventies.
