Oak & Oscar The Humboldt ExP-02vsDOXA SUB 250T GMT

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.

The DOXA SUB 250T GMT is widely praised for its compact and wearable 40mm case, with reviewers noting its slim 10.85mm thickness and short lug-to-lug measurement, making it comfortable on most wrists. Its precise bezel action is described as satisfying, and the watch offers 250 meters of water resistance. The inclusion of a GMT complication is seen as a valuable addition to Doxa's utilitarian dive watch design. However, the skeletonized GMT hand is a point of contention, with some reviewers finding it quirky and less intuitive, especially when compared to the minute hand, though others note it looks better in person and is easily ignored for diving. One reviewer expressed a preference for a "flier-style" movement for a dedicated travel watch. Limited editions are noted as having a slight price premium. The Sellita SW330-2 movement is generally mentioned, with power reserve figures varying between 50 and 56 hours.
