MARATHON 46mm JUMBO DIVER'S QUARTZ (JSAR) WW194018SS-0130

Built for Extreme Conditions

The JSAR, officially known as the Jumbo Diver's Quartz, is a watch specifically designed to guarantee precise timekeeping even under the harshest conditions. Its robust construction makes it the perfect companion for operations where reliability is paramount. Thanks to its high-performance components, it is not only durable but also offers a high degree of functional reliability under extreme environmental conditions – be it during diving operations, at sea, or in challenging terrain.

Maximum Legibility in Any Light

A special feature of the JSAR is its consistently well-thought-out readability. The hour indices and all three hands – hour, minute, and second hands – are equipped with the proven MaraGlo luminous compound. This technology ensures that the time remains clearly visible in all lighting conditions, even in complete darkness or underwater. The combination of large markings and reliable luminescence makes the watch a dependable instrument in all situations where every second counts.

Proven Technology Inside

Inside the watch, a reliable ETA FØ7 High-Torque quartz movement operates, impressing with its robust construction and low maintenance requirements. With three functional jewels, it is designed for longevity and delivers consistent accuracy – even with strong shocks or temperature fluctuations. The watch is complemented by a date window and a dial with a double time scale, clearly displaying both the 12-hour and 24-hour formats.

Well-Designed Case

The JSAR's case also underlines its professional claim: it is made of high-quality 316L stainless steel, which is not only robust but also corrosion-resistant. The brushed surface gives the watch a subtle, functional finish that emphasizes the JSAR's military origin. With a diameter of 46 millimeters and a case thickness of 18 millimeters, the watch appears striking and powerful on the wrist – a true statement that is both practical and ergonomically shaped.

Optimized for Underwater Use

A unidirectional diver's bezel with a 60-minute scale complements the JSAR's range of functions. This can be set precisely and securely – a crucial advantage for dives or time-critical operations. Thanks to the screw-down crown, the watch achieves water resistance of 30 ATM, making it suitable for extended underwater activities. The scratch-resistant sapphire crystal reliably protects the dial from damage and ensures clear visibility in any situation.

Flexible Strap for Every Wrist Size

The scope of delivery includes a high-quality 3-piece rubber strap set, which – like the watch itself – is manufactured in La Chaux-de-Fonds, Switzerland. Made from durable FKM rubber, it meets all requirements for a military-grade carrying device. The set consists of a 6 o'clock end piece with eight adjustment holes and two 12 o'clock buckle pieces in different sizes. This combination allows for individual adjustment to various wrist circumferences, without sacrificing stability or comfort.
