What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Oak & Oscar The Humboldt ExP-02

Oak & Oscar The Humboldt ExP-02 is a 39.5mm stainless steel tool watch featuring a unique, layered aluminum "ghost dial" for legibility and 200m water resistance, powered by a Sellita SW300 movement. Its appeal is limited by a US$2,550 price and an extremely limited production of 20 pieces, with its experimental dial construction done in Chicago. Overall, reviewers highlight the endearing dial and in-house bezel production as key features of the Oak & Oscar Humboldt ExP-02.

Tornek-Rayville Blakjak Time-elapse

The Tornek-Rayville Blakjak Time-elapse is a rugged, dive-capable field watch, an evolution of a 1990s military concept. It features a 42.5mm stainless steel case, a sapphire crystal, and a Seiko NH36 automatic movement with a 40-hour power reserve. The dial is busy but functional, and the watch features Super-LumiNova BGW9. On balance, reviewers note the Tornek-Rayville Blakjak Time-elapse is a modernized military watch with robust dive capabilities.
