Jumbo Day/Date (JDD) Military Mechanical Watch: Large, Steel case. Brand new with box and papers, individual serial number.

The bilingual Jumbo Day and Date (JDD) is the newest addition to Marathon’s line of military watches. The watch features an automatic, self-winding, 26 jewel movement and hands equipped with 16 luminescent tritium gas tubes, crescent shaped sapphire crystal and screw-down crown. Whether it’s day or night, this new watch provides clear visibility with its large dial and numbers. The Jumbo Day and Date includes easy-set bilingual day and date display and is water resistant to 300m/1000ft.

It has a NATO NSN laser engraved on the back and is the first Jumbo Automatic that Marathon has manufactured. Besides having a bilingual Day-Date(English and French), it also has for the first time, two tubes at the 12 and a tube on the center-second hand.

The JDD is same size as Marathon's legendary JSAR. Due to the expansive dial space, Marathon designed the numbers to be very large to increase the already great visibility and, as well, they put the supplemental (military) numbers 13-24 on the inside bezel ring.

Designed for wearers with large wrists, the watch boasts a 46mm diameter x 17mm thick case with a 120 click unidirectional bezel. The large dial and large numbers provide easy visibility. The sweep second-hand includes a tritium tube on the tip. The band is made of 100% vulcanized rubber & fastens with a 316L stainless steel buckle.

This wristwatch is hand assembled in Switzerland.

Also, to top this off, Marathon is using for the first time a slight bombe (curved) sapphire crystal! The movement in this watch is completely made in La Chaux-de-Fonds, Switzerland for Marathon, it is a Sellitta SW220 modified model!
