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.

Yema Superman Tourbillon CMM.31 Limited Edition

Owners praise the Yema Superman Tourbillon CMM.31 Limited Edition as an incredible and crazy watch, appreciating its unnecessary tourbillon complication and impressive specifications at a remarkable price point. The titanium construction contributes to comfort despite the 43mm case size. One reviewer notes the bracelet clasp's extension system is somewhat crude. On balance, owners and reviewers rate the Yema Superman Tourbillon CMM.31 Limited Edition highly for its compelling tourbillon feature at an accessible price.
