Marathon JDD (Jumbo Day/Date) Anthracite Diver's AutomaticvsTissot PR516

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 Tissot PR516 is widely praised for its vintage-inspired design, robust and well-finished case, and the value it offers. Owners and reviewers frequently highlight its crisp dials, heritage inspiration, and modern refinements like the Powermatic 80 movement. Some owners appreciate its size and jubilee bracelet, finding it comfortable and a good alternative to other models. However, several sources note a 14mm thickness that can feel noticeable, and the bracelet clasp is considered a weak point by one reviewer, being a folded steel design. The case design is described by some as unrefined or boring, lacking the appeal of the original 70s model, and one enthusiast finds the hands a dealbreaker. The fixed bezel on some variants is seen as a gimmick by some owners, and the orange subdial hand can be difficult to read. On balance, owners and reviewers rate the Tissot PR516 highly for its strong vintage aesthetic and robust build quality at its price point.
