Marathon Jumbo Day-Date SAR Automatic Dive Watch with White Dial #WW194021SS-0530

The Marathon Large Bilingual Diver’s Automatic is a large dive watch with a day and date function in both English and French. Designed for use by Search and Rescue (SAR) divers, the Large Bilingual Diver’s Automatic is a watch built to withstand the most extreme of conditions. The Large Bilingual Diver’s Automatic is also known as the Jumbo Day Date (JDD).

The Marathon JDD is certified for water resistance down to 30 ATM – 300 meters (1000 feet) underwater. Made from 316L surgical grade stainless steel, the JDD is a hefty, purpose built watch that will not let you down on any adventure you may take it. The crystal of the JDD is a synthetic sapphire which will resist scratches, and ensure maximum dial legibility. The crystal of the JDD is also domed shaped to improve legibility even further.

The JDD is made in La Chaux de Fonds Switzerland to guarantee the highest level of quality and accuracy in manufacturing. Inside the JDD is a Swiss made, Sellita SW220-1 automatic movement with 26 jewels. The JDD uses self contained Tritium gas tubes to ensure constant visibility in low light situations, a gas tube is placed on each hour marker as well as the hour and minute hands and uses MaraGlo paint for the 12 hour bezel marker. Tritium tubes are self illuminating gas tubes which contain an isotope of hydrogen, meaning they will not dull down in brightness like normal photo-luminescent paint which requires an external light source to create a glow.

Features a 3 Piece Rubber Strap System (made in La Chaux-de-Fonds, Switzerland) crafted from FKM Rubber to meet the requirements of high-performance military applications. The 3-Piece system comes with one (6 o'clock) tail piece with 8 adjustment holes, and two (12 o'clock) buckle pieces of different sizing that allow the wearer to tailor the length to fit their wrist size.

The JDD combines Military toughness with Swiss craftsmanship in a watch that will get the job done, and look good doing it.
