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.

LONGINES AVIGATION BIGEYE

Owners and reviewers widely praise the Longines Avigation Bigeye for its unique, asymmetric dial, vintage military aesthetic, and cohesive design, with one reviewer noting its GPHG Best Revival prize win. The tactile chronograph pusher action and reliable L688.2 column wheel movement are highlighted, as is the watch's legibility and versatile strap-swapping potential due to its 20mm lug width. However, criticisms include the 30-minute sub-dial's three-minute hash marks, which some find compromise reading speed, and the lack of drilled lugs. The watch's thickness, around 14.45mm, is noted as typical for its movement, and some owners mention minor QC issues with chronograph hand alignment and a loud rotor. On balance, owners and reviewers rate the Longines Avigation Bigeye highly for its distinctive vintage-inspired design and solid chronograph performance at its price point.
