Marathon JDD (Jumbo Day/Date) Anthracite Diver's AutomaticvsVelini Crosshair

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 express disappointment with the ST1701 movement, citing poor regulation and reliability issues in previous Seagull movements, though some find the watch's design attractive. On balance, owners rate the Velini Crosshair poorly due to concerns over movement reliability.
