I love the Santos–history, refinement, bracelet, bezel and Cartier is having a moment these days. Omega is second choice but they are very different and you should think about how often you will wear and in what circumstances. Cartier can be a pretty formal watch (it comes with leather strap usually) and can be dressed down. Hard to dress up the Omega much beyond being a diver.

Has Nomos ever done a central seconds hand? That has been the show stopper for me on the brand = I like a big sweeping second hand.
