Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
The Olech & Wajs Watches M-52B AF is a 39.5mm tool watch with 300m water resistance and a Soprod P024 automatic movement. It features a PVD-coated bezel and a dial with a B-52 bomber outline, which some find too prominent and can obscure the hands. The watch is a limited edition of 56 pieces, priced at CHF 1,256, with pre-orders opening January 12, 2024. On balance, owners and reviewers note the Olech & Wajs Watches M-52B AF for its distinct tactical design and robust build, though the prominent B-52 graphic on the dial is a polarizing element.
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.
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.
