Not every wrist is suited to a 41mm watch, and Marathon knows it. The JDD exists for larger wrists that want a true tool diver in proportion, and reference WW194021SS-0111 delivers it with a matte black NGM dial on a stainless steel bracelet.

Numbers tell the story: 46mm wide, 18mm thick and 55mm from lug to lug, with 22mm lugs. That is a substantial watch, and it is meant to be. On a broad wrist, the JDD sits in balance, with a dial big enough to read at a glance and day and date windows that do not require squinting. If you have found standard divers looking undersized on you, this is the Marathon to try.

The specification lives up to the size. The Sellita SW220 automatic movement provides day and date with 26 jewels, Incabloc protection and roughly 41 hours of reserve. Its 316L steel case carries a screw-down crown between crown guards and resists water to 300 meters. A domed sapphire crystal covers a matte black dial with no government markings, tritium gas tubes on the indices and hands, and a bilingual English/French day wheel. The 120-click unidirectional bezel is easy to turn even with gloves, and its pip uses MaraGlo. The stainless steel bracelet finishes the watch with a solid, secure fit.
