Rubber strap, black dial, Swiss automatic heart: the Marathon MSAR Auto WW194026SS-0130 is the medium Search and Rescue diver in its most water-friendly configuration. At 36mm, it brings genuine 300-meter capability to wrists that find most dive watches too large.

This listing ships on a 3-piece FKM rubber strap kit, made in La Chaux-de-Fonds where Marathon assembles its watches. FKM rubber shrugs off salt water, chlorine and sweat, dries quickly, and stays supple, which is exactly what you want after a lake swim or a long day on a boat. The strap's light, flexible feel also keeps attention on the watch itself: a matte black Standard-Issue dial signed only MARATHON, tritium gas tubes on markers and hands, and a date at 4:30.

The case follows the SAR formula Marathon developed to Canadian Government requirements, with brushed 316L stainless steel, a sapphire crystal, a screw-down crown protected by guards and an oversized unidirectional bezel designed for gloved hands. A Sellita SW200-1 automatic movement with 26 jewels and Incabloc shock protection keeps it running from the motion of your wrist. On rubber, the 36mm case and 18mm lugs feel almost weightless, making this an easy watch to forget you are wearing until you need it.
