Here's a 1947 Omega "bumper" in a rare jumbo size.
Check out that cool, silver two-tone dial with Roman Numerals. The chapter ring. The blued seconds hand. The perfectly patina-ed hour and minute hands.
The case is a hefty 35mm across excluding the crown, by 42mm from lug to lug. A word about the case: It's a screw-back, not a pop-off, and it has those great dog-leg lugs.
Under the hood is the bumper Cal 351 movement, keeping excellent time.
