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.

Sinn U50 SDR with TEGIMENT option

The Sinn U50 SDR with TEGIMENT option is widely praised for its robust submarine steel construction, impressive 50bar water resistance, and excellent anti-reflective coating. Owners and reviewers highlight its toolish, legible dial, satisfyingly tactile bezel, and the outstanding scratch resistance provided by the TEGIMENT hardening. Some owners note the lume is underwhelming, and a few find the clasp aesthetically large and chunky despite its functional diver's extension. Overall, owners and reviewers rate the Sinn U50 SDR with TEGIMENT option highly for its exceptional build quality and scratch resistance at its price point.
