Reviews

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

Seiko 5 Sports SKX series

The Seiko 5 Sports SKX series is widely praised as an excellent value gateway watch, with owners and reviewers highlighting its solid build and powerful lume. The 22mm bracelet is noted for its comfort, and the watch offers numerous style options. Some owners find the original SKX models heavy and bulky, while others appreciate their ruggedness and iconic dive watch design. The Seiko 5 Sports SKX series offers an upgraded movement with hacking and hand-winding, and standard spring bars for easier strap changes. However, it lacks the screw-down crown and ISO certification of the original SKX, leading some to consider it less of a tool watch. On balance, owners and reviewers rate the Seiko 5 Sports SKX series highly for its value and modern features, despite some preferring the tool watch capabilities of its predecessor.

Thorn Diver 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.
