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.

Marathon Jeep Rubicon TSAR

Marathon Jeep Rubicon TSAR owners praise its toughness and 41mm size for a 7" wrist, noting the sapphire crystal remains nearly flawless after a decade of near-daily wear and abuse. Tritium lume is still acceptable in darkness, and the bezel, though missing its 0-mark triangle, remains tight and clicks solidly. The watch features a steel case water-resistant to 300 meters, a Sellita SW200-1 automatic movement, and dual branding that de-emphasizes Marathon. Overall, owners rate the Marathon Jeep Rubicon TSAR highly for its exceptional durability and practical size.
