Marathon JDD (Jumbo Day/Date) Anthracite Diver's AutomaticvsOrient Multi-Year Calendar

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.

Owners report the Orient Multi-Year Calendar features a complex analog display for tracking days and dates across multiple years, housed in a 45mm stainless steel case with 100m water resistance. Some owners view the watch as a visually appealing novelty, noting that manual adjustment is required for months and that the older 20-year calendar version is difficult to find. One owner observed only light signs of wear on their watch, with minor desk rash on the buckle visible only under magnification. On balance, owners appreciate the unique calendar complication as a visually appealing novelty.
