The Marathon JSAR (Jumbo Search and Rescue), or Diver’s LGP (Le Grand Plongeur) is a professional quality diver’s watch with a high-torque, superb, Swiss ETA F07 quartz movement housed in an very large case. The JSAR is manufactured in accordance with ISO 6425 standards, and is designed for Search and Rescue (SAR) divers, field operations, and pilot use. This heavy duty Swiss timepiece can take it all: from the office, to 1000' depths, to the battlefield.
The ultra-clear crystal is also "jumbo", and is made of a synthetic sapphire material. The crystal is scratch resistant and treated with an anti-reflective coating for maximum readability. And since you can take this watch down to 300m / 30 ATM / 1000' depths, the extra clarity will prove beneficial! A unidirectional bezel (elapsed time ring) gives you time accurate tracking, and the 12 and 24 hour time scales will meet the needs of civilian and military personnel alike.
As you'd expect with a high-quality Marathon dive watch, the legendary JSAR is handmade in La Chaux de Fonds Switzerland. It's a true Swiss watch with military toughness. The ETA Jumbo F07 movement brings you accurate timekeeping, and the MaraGlo photo-luminescent material keeps the hands and markers visible in low light. (MaraGlo requires charging with an external light source, and will continue to glow on its own for 8 hours after being exposed to light.)
The modern, streamlined appearance of this watch is enhanced by the 22mm wide, 100% vulcanized rubber strap and 316L stainless steel buckle. The black background date wheel with easy-set date function round out the look. On the back of the watch, you'll find engraved markings detailing the serial number and other details to assist with maintenance and traceability should anything happen to your watch. Commonly called the JSAR (pronounced "jay sarr").
