Marathon JDD (Jumbo Day/Date) Anthracite Diver's AutomaticvsTornek-Rayville TR-660 Acrylic Date

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 widely praise the exceptional build quality for the price, noting a solid feel, quiet rotor, and good bezel action on the Tornek-Rayville TR-660 Acrylic Date. Reviewers highlight its utilitarian, non-reflective matte black dial and the inclusion of a moisture detector, echoing its military-issued predecessor. One owner found the lume dim and short-lived. Overall, owners rate the Tornek-Rayville TR-660 Acrylic Date highly for its robust construction and military-inspired design cues at its price point.
