Reviews

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

DOXA SUB 250T GMT

The DOXA SUB 250T GMT is widely praised for its compact 40mm case, slim 10.85mm thickness, and sub-43mm lug-to-lug measurement, making it exceptionally comfortable and wearable. Reviewers highlight its functional GMT complication, precise bezel action, and the classic Doxa design language, noting its competitive pricing around €2,550 or $2,450. The skeletonized GMT hand is a point of discussion, with some finding it quirky or less intuitive, though others note it looks better in person and is easy to ignore for dive purposes. The watch is available in nine dial colors, with specific limited editions carrying a slight premium. Overall, reviewers rate the DOXA SUB 250T GMT highly for its wearable dimensions and value proposition as a capable dive watch with added GMT functionality.

From video reviewers

The watch's refined and wearable 42mm case size is a strength. Reviewers noted the iconic Doxa aesthetic combined with GMT functionality. No shared weaknesses were identified.

Thorn Diver T023 V2

Owners widely report the Thorn 40mm PT5000 Automatic Dive Watch T023 V2 offers a slim wearability and vintage sub aesthetic, with one owner calling it a phenomenal homage and underpriced for its smooth PT5000 movement, tophat sapphire, and bezel. However, some owners flag concerns about quality control, with reports of a loose bezel, dial movement when setting time and date, and an inconsistent crown. Accuracy figures vary, with one owner noting 0/+2 seconds per day for the PT5000 movement, while another experienced a power reserve of only 6 hours and 20 minutes. On balance, owners rate the Thorn 40mm PT5000 Automatic Dive Watch T023 V2 highly for its comfortable wearability and vintage design at its price point, despite some reported quality control issues.
