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 GMT

Oak & Oscar The Humboldt GMT owners widely praise its exceptional accuracy, often running at or near 0 seconds per day, and its comfortable wearability with subtle design details. The construction quality for the price point, sandwich lume, and anti-magnetic properties are also highlighted. Some owners find the bracelet sizing adjustment slightly awkward, and one noted the lume could be brighter. Overall, owners rate the Oak & Oscar The Humboldt GMT highly for its accuracy and comfortable wearability.

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.
