Marathon JDD (Jumbo Day/Date) Anthracite Diver's AutomaticvsDOXA SUB 300

Owners widely praise the Marathon JDD (Jumbo Day/Date) Anthracite Diver's Automatic as a tough, underrated tool watch with lifestyle appeal, highlighting its robust build and tritium lume for excellent legibility. However, its 46mm size is a common criticism, with some finding it heavy and top-heavy, and the OEM rubber strap stiff. One owner noted the watch runs about 10 seconds fast after three days, and the ETA 2836-2 movement offers approximately two days of power reserve. On balance, owners and reviewers rate the Marathon JDD (Jumbo Day/Date) Anthracite Diver's Automatic highly for its robust tool-watch build and legibility, despite its substantial size.

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.
