What people say

Owners + reviewers, side by side

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

Seiko Prospex SPEEDTIMER Seiko 145th Anniversary Limited Edition

Owners widely praise the Prospex SPEEDTIMER Seiko 145th Anniversary Limited Edition for its refined presence and intricate dial patterns, with some favoring its unique red dial and steel bezel over other Speedtimer models. However, some owners criticize the 24-hour subdial as useless, the date window as recessed, and the stock bracelet as difficult to fit, while others find the pushers stick out too much. One owner notes the $995 price point is high for the 6R55 movement, suggesting a lower range, though others appreciate the Seiko finishing and charm. On balance, owners rate the Prospex SPEEDTIMER Seiko 145th Anniversary Limited Edition well for its unique aesthetic and finishing, despite some functional and value concerns.

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.
