What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Grand Seiko SBGM245

Owners widely appreciate the Grand Seiko SBGM245 for its blend of sport and luxury, with one enthusiast highlighting its superior workmanship over quartz movements. However, opinions on its size vary, as one owner found the SBGM245 too large, preferring the comfort of a different variant. Overall, owners value the Grand Seiko SBGM245 for its refined craftsmanship, though its wearability is a point of personal preference.

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.
