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.
