Arctic Edition Jumbo Day/Date Automatic (JDD) - 46mm

The Marathon 46mm Arctic JDD is a rugged and reliable dive watch engineered for use in the most extreme conditions. This model features a stark white dial specially chosen to reduce glare in bright environments. Designed in Canada, this watch is Swiss-made and features a 26 Jewel Sellita SW220 movement with Incabloc™ shock absorber providing premium precision. The watch also includes a day/date calendar, equipped with Rapid Day Date Correction which allows for easy adjustment of the day and date.

The outer shell of the Jumbo Day/Date (JDD) consists of a 316L stainless steel case with a brushed finish (measuring 46mm in diameter and 18mm thick), a screw-in crown, and a sapphire crystal. The unidirectional bezel with 60-minute scale and two scale quantities (1-12 and 13-24) ensures precise timing for professional or recreational diving. The JDD also features tritium gas tubes on all hour markers and the full hand set for constant illumination in low light conditions, with a double tritium marker at the 12 o'clock position and a MaraGlo™ bezel pip for easy orientation. The watch is rated for a submersibility of 30ATM, allowing the JDD to function at depths of up to 300M (1000FT) underwater.

The JDD is hand-assembled in La Chaux-de-Fonds, Switzerland, ensuring the highest level of craftsmanship and accuracy. To maintain the watch's precision and longevity, see our care guide.
