MARATHON 46mm JUMBO DAY/DATE AUTOMATIC (JDD) WW194021SS-0130

Strength and Precision in Military Design

The Jumbo Day/Date Automatic – JDD for short – is more than just a classic mission watch. It was developed from the ground up for everyday military use, combining uncompromising functionality with impressive robustness. With a case diameter of a full 46 millimeters, it is one of the most striking models in the SAR line, making it well-equipped to perform confidently even in extreme conditions. The case is made of durable 316L stainless steel with a brushed finish, which not only provides a subtle look but also protects against disruptive light reflections – a crucial advantage in tactical operations.

Designed for International Missions

Inside the JDD, a precise, Swiss-made automatic movement operates: the Sellita SW220 guarantees reliable timekeeping and is further protected by the proven Incabloc™ shock protection system. With 25 jewels, this movement ensures not only smooth operation but also high durability – even under constant strain. Particularly practical: The day and date window is bilingual and can be displayed in both English and French. This makes the watch ideal for multinational operations where flexibility and comprehensibility play an important role.

Visibility Day and Night

Regarding readability, the JDD employs a dual solution: Firstly, tritium gas tubes are used, which, due to their self-luminous properties, ensure consistently good visibility – regardless of external light. Secondly, the proven MaraGlo technology has also been integrated, providing quick charging and strong luminescence, especially with short light impulses. This combination makes the JDD a reliable timepiece even in complete darkness.

Protection Where It Matters Most

Another important element in the watch's construction is the scratch-resistant sapphire crystal, which reliably protects the dial from mechanical impacts. The screw-down crown and the solid construction of the case contribute to its high water resistance – the JDD is pressure-resistant up to 30 ATM. This means it can easily withstand longer underwater missions. The unidirectional rotating bezel with a 60-minute scale also allows for precise time measurement, for example during diving or tactical operations.

Assertive in Every Situation

With a lug width of 22 millimeters and a case thickness of 18 millimeters, the JDD conveys a sense of stability and strength from the very first wear. Despite its size, its ergonomic design ensures a comfortable fit on the wrist and does not interfere even during prolonged use. The included three-piece rubber strap set offers additional comfort and can be individually adjusted – ideal for changing operational conditions or extreme temperatures. Overall, the Jumbo Day/Date Automatic embodies a well-thought-out combination of function, reliability, and technical sophistication – perfectly tailored to the real demands of military personnel in active service.
