Dr No[Moderator Omega - Wristscan]

Actually, no. Omega's cal 2201/2211 movements, based on the Unitas 6498, requires . . .
. . . a 49(.2!) mm case to present the subsidiary seconds dial in the aesthetically 'correct' position.
As an aside, Dornblüth created their 99.1 caliber to replicate the same position in a 42 mm case. Omega could've replicated Dornblüth's solution to offer a smaller case, but obviously didn't.
These Railmaster references from ~ eight or nine years ago were the first manual wind chronometers has Omega offered since the cal 602 Genèves of the late '60s.
