This one came last week, had to get a crystal made for it and picked it up today. Ref. CK 901 Cal. T17 From 1939 25 mm X 39 mm. ex. crown It came on and very old Omega strap and buckle. I dont recall have seen this type of strap with a keeper of that type before. Could it have been the original strap? Next will be to find a correct style crown, and get a service (it works but is dirty) credit to @Tire-comedon
Hi I loved the T17 , had a 60 hour power reserve , longest Omega had till like the Railmaster XXL .... If i remember correctly.. Very cool Good Hunting BIll Sohne
Your strap look very identical to the one in ad: grain, stitches & shape ... so I think it is original strap.
Correct, 60 hours power reserve, the longest on a Omega until caliber 8500 in 2006 Have a couple of other T17 CK 921 CK 3516: CK 891:
I think the strap is an old replacement, the original would have been a much better fit, even with age shrinkage. A new crown and that will look beautiful.
that is my absolute favourite case shape for these early ones..... mine has a F 20 caliber. kind regards. achim
