Could someone tell me what model this watch is?
You can cut them shorter yourself. See this tutorial. I've done this with nylon and leather, though you obviously don't need to use a lighter on the leather.
Not in the case of the kangaroo. The regular kangaroo will stretch over time, however.
The Kangaroo Tail will not stretch and is only slightly thicker.
Apologies for the Rolex, but it IS Vintage!
Thanks. Since this thread started describing a late model Omega as a "Poor Man's Watch", I should point out that if you can afford a new Omega, you can certainly afford a vintage Rolex.
Indeed based on purist criteria I would point that there are "good" watches, that is to say watches worth appreciating on their own, at almost every price point.
