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.

Glycine Airman No. 1 Purist

The Glycine Airman No. 1 Purist is praised as a faithful re-creation of a historical 24-hour watch, with one owner purchasing it for $620 and viewing it as a long-term keeper due to its heritage reissue status and vintage aesthetics. The 36mm size is noted as a conversation starter. However, the acrylic crystal is prone to scratching, with one example showing a small scratch over the date window. Some community members suggest pre-Invicta models may hold value better. Overall, owners appreciate the Glycine Airman No. 1 Purist for its authentic vintage appeal and unique dial, though the acrylic crystal requires careful handling.
