Wow, that level of strap to dial matching is unprecedented! Looks almost like you have a display front case whereby strap continues behind watch and is visible through the front of the dial... unreal! The colour photo looks like a piece of wall art!
Old-omegas.com has a page of vintage catalogues. It was neat finding this one listed. It was surprisingly cheap in the'70s Sent from my iPhone using Tapatalk
A new arrival from the Far East. It's kind of hard to date, because it lacks a case SN, but I believe it is from the late '20s, not long after the development of the Oyster case. 32 mm silver case.
