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.

Sugess Heritage S455

Owners appreciate the Sugess Heritage S455's classic, clean dial protected by a sapphire crystal. One owner suggests removing the fake blue jewel on the crown. On balance, owners value the Sugess Heritage S455 for its clean dial design.

From video reviewers

The Sugess Heritage S455 has a smooth and precise bezel action. The watch's value at the price point is a notable strength, with a fully functioning tourbillon typically found in high-end watches. However, the watch has a relatively weak lume brightness.
