Reviews

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

Seiko 62MAS

Owners widely praise the Seiko 62MAS for its beautiful vintage-inspired finishing, crisp bezel action, and overall build quality, with many appreciating its comfortable 40.5mm case and slim apparent height. Some owners report accuracy issues with the 6R movement, while others find it runs within specifications, and opinions are split on whether the 40mm size is too large for smaller wrists, with some noting it can wear top-heavy. The price point is considered high by some, though others deem it fair for a new watch. Overall, owners and reviewers rate the Seiko 62MAS highly for its faithful recreation of the original design and refined modern interpretation.

From video reviewers

The 37.5mm-38mm case size is a significant strength, offering a historically accurate and comfortable fit. Reviewers did not agree on any specific weaknesses.

Trematic T-Five Beigua Maris

The Trematic T-Five Beigua Maris is lauded for its 40mm grade 5 titanium case with mixed finishes and a smooth 120-click bezel action. Reviewers highlight its attractive specifications for the price, including the La Joux-Perret G101 automatic movement, and note its well-proportioned 40mm diameter. One owner reported excellent customer service, receiving a replacement watch within a week. However, the Lumicast hour markers' glow duration and brightness are slightly below expectations, and the minute track's design can hinder precise legibility. Overall, owners and reviewers rate the Trematic T-Five Beigua Maris highly for its value and build quality, particularly the titanium case and reliable movement.
