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.

Studio Underd0g Full Moon

Owners widely praise the Studio Underd0g Full Moon's harmonious creamy dial and its 37mm case, which fits flawlessly. The innovative sapphire disc with numerals is a highlight, though two visible screws holding it are noted as a minor aesthetic drawback. Some owners find the watch overpriced, while others see value in the upgraded Sellita movement under $1k. Lume is surprisingly good, and the included NATO strap is preferred by some over the leather. Accuracy ranges from +1/+2 seconds per day to about -6 seconds per day. On balance, owners rate the Studio Underd0g Full Moon highly for its versatile dial and well-fitting case at the price point.
