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.

Phoibos Leviathan

Owners widely report the Phoibos Leviathan offers a vintage experience at an affordable price due to its proportions and conservative design. However, the watch is considered well-made and sturdy but quite heavy, with a 45mm x 54mm lug-to-lug case and a 15.5mm thickness, leading some owners to replace the stock band. On balance, owners rate the Phoibos Leviathan highly for its vintage feel and sturdy build at its price point.

From video reviewers

The watch features 500m water resistance and a Seiko NH35 automatic movement. The case size is a point of contention, with reviewers noting it is substantial and may overwhelm smaller wrists, while others highlight a 40mm case size as an improvement.
