MARATHON 36mm MSAR Medium Diver Automatic – WW194026SS

Iconic Precision for Extreme Situations

Commonly known as the GSAR – Government Search and Rescue – this model is considered the most traditional and established within Marathon's SAR collection. The GSAR is not just a tool, but a symbol of reliability and robustness in extreme conditions. Designed for professional rescue workers and military use, it combines uncompromising technical quality with a functional, practical design.

Swiss Engineering at its Heart

Inside the GSAR operates a precise automatic movement with mechanical self-winding, manufactured in Switzerland. The proven SW200-1 caliber from Sellita Watch Co. SA, based in La Chaux-de-Fonds, is used. Equipped with 26 jewels, Incabloc shock protection, and a maximum power reserve of 41 hours, this movement guarantees consistent and long-lasting performance – even under the most difficult conditions. With a frequency of 28,800 vibrations per hour, the watch is not only precise but also pleasantly smooth in the movement of the second hand.

Robust Construction, Made for Action

The case is made of brushed 316L stainless steel, known for its corrosion resistance and durability. With a diameter of 36 mm, a height of 14 mm, and a lug-to-lug length of 43.5 mm, the GSAR offers compact but extremely resilient dimensions – ideal for daily use in challenging conditions. The screw-down crown ensures additional water resistance, achieving a water resistance of 300 meters (30 ATM). The bezel is unidirectional rotating and equipped with 120 clicks and a MaraGlo-illuminated marker – an essential detail for diving operations or precise underwater timekeeping.

Clear Readability Day and Night

The matte dial emphasizes the functional character of the watch. The indexes as well as the hour, minute, and second hands are equipped with self-luminous tritium tubes, which remain constantly visible even without external light sources. Thanks to this technology, reliable readability in complete darkness is guaranteed. The date display is placed at 4:30 to keep the dial symmetrical and clearly structured.

Adaptable with Versatile Strap Options

To meet the most diverse requirements, the GSAR can be combined with various straps. It comes standard with a black rubber strap including a stainless steel pin buckle. Alternatively, a solid stainless steel bracelet with a folding clasp is also available, which provides additional stability and a high-quality wearing experience.
