Marathon JDD (Jumbo Day/Date) Anthracite Diver's AutomaticvsSeiko Presage Style60's

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 Seiko Presage Style60's collection is praised for its pleasing retro aesthetic, with reviewers highlighting the box-shaped crystal, faceted indexes, and applied markers. Specific models are noted for their smaller 39.5mm case size and comfortable new bracelet, alongside a charming steel bezel, though this bezel is decorative. The collection offers an affordable price point, with time-and-date models costing €490-€540 and GMT versions at €670. However, the automatic 4R35 movement's claimed accuracy tolerance of +45/-35 seconds per day is flagged as a potential dealbreaker by multiple sources. The Open Heart models feature a 41-hour power reserve and a 24-hour sub-dial, with one reviewer expressing a personal dislike for open-heart dials and questioning the strap choice on a specific rose gold PVD model. GMT models use the 4R34 automatic GMT movement, while open-heart versions use the 4R39 movement. All models feature Hardlex crystals and 50m water resistance.
