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 V3.1 Edition

Owners widely praise the Thorn 40mm PT5000 Automatic Dive Watch T023 V3.1 – Upgraded Bracelet Edition for its desirable vintage feel, spot-on proportions, and classic case and dial design, with one owner calling it the best vintage diver homage. The PT5000 movement is noted for its accuracy, with one report of 0/+2 seconds per day, and is described as smooth. The upgraded bracelet is a favorite for many, though some find its riveted construction difficult to adjust and one owner considers its quality lesser compared to another model. On balance, owners rate the Thorn 40mm PT5000 Automatic Dive Watch T023 V3.1 – Upgraded Bracelet Edition highly for its vintage aesthetic and smooth movement at its price point.
