Thorn 40mm PT5000 Automatic Dive Watch T023 V3.1 – Upgraded Bracelet 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.

Zelos Spearfish 3

The Zelos Spearfish 3 is widely praised for its exceptional finishing, with razor-sharp polish and flawless brushed transitions that owners feel exceed its price point. The 40mm case is noted for its wearability, and the La Joux-Perret G100 movement offers a 68-hour power reserve, with reported accuracy averaging +2.6 seconds per day. Reviewers highlight the exceptionally smooth bi-directional bezel and a tool-less micro-adjustment clasp described as best-in-class among microbrands. The sapphire sandwich construction and lumed bezel are also cited as desirable features. Overall, owners and reviewers rate the Zelos Spearfish 3 highly for its outstanding finishing and value at its price point.

From video reviewers

The La Joux Perret G100 movement is a significant strength. The bracelet's refinement is a weakness. Reviewers disagreed on the dial material, with one noting a burnt orange sunburst and another mentioning meteorite.
