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

The DOXA SUB 300 is widely praised for its wearability and vibrant color options, with reviewers noting its compelling charm and modern updates like improved lume and a meter-based bezel. Owners report the DOXA SUB 300 wears comfortably, with its cushion case and beads-of-rice bracelet contributing to a smaller perceived size. The COSC-certified ETA 2824-2 movement is noted for its accuracy, with one owner seeing it gain only +1 second in three days. However, some owners flag issues with the bracelet's end links sticking out and a sharp clasp edge, while one reviewer found the lume to be a disappointment. The polished bezel surface is also noted as prone to scratches. Overall, owners and reviewers rate the DOXA SUB 300 highly for its wearability and distinct design, despite some minor finishing concerns.

Tissot Gentleman Open Heart

Owners widely praise the Tissot Gentleman Open Heart for its versatile dressy-sporty aesthetic and elegant sunburst dial finish, with one owner preferring its less shiny blue dial compared to other versions. The watch offers excellent fit and bracelet adjustability, and its modified Powermatic 80 movement achieves COSC-level accuracy of -3 to +5 seconds/day, though the seconds hand movement is slightly less smooth at 6 movements per second. However, one owner reported the watch arrived non-functional, requiring a return due to an inoperable movement. On balance, owners rate the Tissot Gentleman Open Heart highly for its aesthetic appeal and accurate timekeeping, despite a reported instance of a faulty movement.
