Hello all, I have recently come across an Omega Constellation belonging to my late grandfather and I am simply looking for any available information on this model, or a point in the right direction. I thought that this community may be of assistance! Best, Matthew
The best answer is to take it to a watchmaker and have the caseback removed. Omega stamps the reference number inside. Take a clear, preferably high resolution photo of that and all the numbers on the movement. Post the photos here and you'll get more info than you ever wanted.
Alright, took a couple days but here is some more info - This was forwarded to me from the service centre, so unfortunately I do not have any additional photos. Caliber: 1001 Case Reference: 168044 Serial# 18668 If there is any information regarding this watch that some of you might have I would really appreciate it! Would love to learn more about it. Best, Matthew
https://www.omegawatches.com/watch-omega-constellation-omega-st-168-0044 The serial number is missing some digits. Serial should be in the 32-34 million range. I thinks it's needless to say that the bracelet on it isn't correct.
I am not familiar with this reference but from a quick Google your watch seems to date to 1970 and is 22k gold plated. The watch is called a Tonneau due to its shape, means barrel shaped in French apparently. If you search up Omega cal 1001 you should be able to find plenty info on the movement. Not a popular collectors model but still interesting none the less.
