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.

KUOE ROYAL SMITH 90-010

Owners praise the KUOE ROYAL SMITH's elegant 37mm size, symmetrical bicompax layout, and crisp chronograph pushers with a swift reset. The salmon dial is described as copper-toned with highly polished, legible Breguet numerals. Some owners find the 13mm thickness and 43mm lug-to-lug wearable, while others note the 14.3mm thickness detracts from wearability. The TMI NE86A movement has a claimed 45-hour power reserve and accuracy ranging from +25/-15 seconds per day. On balance, owners and reviewers appreciate the KUOE ROYAL SMITH for its retro charm and enjoyable chronograph operation, despite some reservations about its thickness.
