Reviews

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

Orient Kamasu

Owners widely praise the Orient Kamasu for its exceptional value, robust build quality suitable for daily wear, and appealing design features like applied indices and a sunburst dial. Reviewers and owners alike highlight its strong lume, sapphire crystal, hacking and hand-winding F6922 movement, and comfortable, well-proportioned case. However, multiple sources note that the bezel exhibits noticeable play and can sometimes become sticky, while some owners find the bracelet's hollow end links and pressed clasp to be a weak point, with one owner reporting a rattle and another finding the crown difficult to grip. On balance, owners and reviewers rate the Orient Kamasu highly for its impressive finishing and features for the price point, making it a standout value diver.

From video reviewers

The Orient Kamasu's compact package makes it suitable for smaller wrists without compromising wrist presence. A notable weakness is that the bracelet is decent but may have some issues, although the reviewer does not elaborate. Reviewers disagree on the value for money, with one highlighting the affordable price and in-house movement, while the other implies a trade-off in value.

Thorn 40mm PT5000 Automatic Dive Watch T023 V1

Owners widely praise the Thorn 40mm PT5000 Automatic Dive Watch T023 V1 for its value and vintage aesthetic, with many appreciating its wearability and proportions, which contribute to a slimmer profile than many similar watches. The PT5000 movement is specifically lauded for its smooth second-hand sweep and impressive accuracy, with one owner reporting within 0/+2 seconds per day. The bracelet is noted as a point of contention, with one owner finding it of lesser quality compared to other Thorn retro diver models. Overall, owners rate the Thorn 40mm PT5000 Automatic Dive Watch T023 V1 highly for its vintage charm and smooth-running movement at an accessible price point.
