A modified 2915-2

Dear all,

I’ve had this watch for over 10 years now but never took the time to research the speedmaster’s long history.

I inherited the watch from my grandfather. He probably bought it new in Switzerland, although I don’t know when. I don’t have the original papers.

The watch was sent to Omega for a service in 2007. From them, I learned that it was a CK2915-2 (although they call it a ST2915-2), with a caliber 321 number 15996XXX.

Recently, when I researched what a 2915-2 should look like, I realized that the watch had been much modified (probably by Omega themselves), and that the bezel, the dial and the hands all do not correspond to a 2915-2.

The case is original. The case back looks original too with its typical « double step ». I’ve read that there could be early case backs without engraving.

My question to you is this one : should I try to have it restored, knowing that it is virtually impossible to find original parts for 2915-2 ? If so, who should I contact (preferably in Europe)? I called Omega in Switzerland and they told me they don't have the spare parts to restore.

Or should I just leave the watch like this, and enjoy wearing it as it is...

Thanks for your advice

That service in 2007 destroyed roughly $ 24.000 of the value. In keeping the replaced parts, somebody in Biel is getting rich....

I believe the modifications were made earlier, maybe in the 1980´s… probably people did not care about vintage watches then
