The B&R Divers look nice and unique although at its retail price, i could get a pre-owned basic Rolex (OP39 blue dial) but the Rolex would look really, really pedestrian beside it. The new Autavia Isograph looks interesting but being a Tag, i do find them over priced here.
As for the Zenith, i actually prefer the skeleton version. Nice open worked dial, thin profile, titanium case and the cool blue croc/rubber strap has me drooling over it.
Difficult choice for sure, both coming in at a similar price point.
