Tudor Pelagos

Tudor's no-compromise professional diver, and the tool watch at its most serious. Where the Black Bay plays on heritage, the Pelagos is all function: a lightweight titanium case, a ceramic bezel, big luminous markers, and a clever self-adjusting clasp for a wetsuit, all running Tudor's in-house automatic movement. The line splits into the deep-diving Pelagos 42 (500m, helium valve), the more wearable Pelagos 39 (200m, no valve), and the Pelagos FXD, a fixed-lug version with genuine French Navy combat-diver provenance. It's about as much real dive watch as you can buy without going custom, and it wears its purpose openly.
