Reviews

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

Nezumi Studios Baleine

Owners widely praise the Nezumi Studios Baleine for its stylish design updates, comfortable 40mm case size, and the soft feel of its strap, with one owner noting its striking appearance garners significant attention. Reviewers highlight its exceptional value, with the automatic version priced competitively, and appreciate the coin-edged bezel action. The watch features a boxed sapphire crystal, signed crown, buckle, and case back, and a textured matte black dial with applied numerals filled with warm-toned lume. Accuracy figures for the Miyota 9039 movement are stated as -10/+30 seconds per day, though actual performance is expected to be better, with one owner reporting initial fast running that settled. Some owners find the 40mm size ideal, while one wished for a smaller case. The gold DLC coating is a matter of personal preference, though it is acknowledged to be eye-catching. The included leather strap did not hold up well to sunscreen for one owner.

From video reviewers

The cohesive, original vintage-inspired design is the primary strength. Lume performance is a weakness.

Orient AA02 Diver

Owners widely praise the Orient AA02 Diver Watch for its exceptional value and quality at its affordable price point, with many considering it a "keeper" and a "proper dive watch" offering better specifications than comparable models. Reviewers and owners alike highlight its accuracy, robustness, and understated, versatile design suitable for any occasion. The Orient F6922 automatic movement is noted for its hacking and hand-winding capabilities, and a 40-hour power reserve. Some owners have opted to replace the stock bracelet. Overall, owners rate the Orient AA02 Diver Watch highly for its impressive value and solid dive watch credentials.
