What people say

Owners + reviewers, side by side

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

DOXA SUB 300 Carbon

The DOXA SUB 300 Carbon is widely praised for its exceptionally lightweight and comfortable forged carbon case, making it an ideal vacation or everyday watch. Owners and reviewers highlight the vibrant dial colors, the satisfyingly clicky bezel action, and the comfortable, adjustable rubber strap with a clever clasp. Its COSC-certified ETA 2824-2 movement is noted for reliable timekeeping, with one owner reporting +0.9 seconds per day and another an average of +5 seconds per day, though a 38-hour power reserve is a trade-off for its slimness. Some reviewers point out that the no-decompression bezel markings may not align with current diving science and that the luminous markers are less bright than some alternatives. The integrated rubber strap requires cutting to size, and the clasp has sharp edges. On balance, owners and reviewers rate the DOXA SUB 300 Carbon highly for its unique, lightweight carbon construction and comfortable wearability.

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.
