Marathon OSAR-D: A Military-Grade Timepiece Built for Performance
The Marathon OSAR-D is a watch designed for professionals who operate in the most demanding environments. Originally built for military personnel, first responders, and search-and-rescue teams, this watch combines durability, precision, and functionality.
Whether used in deep-sea dives, high-altitude missions, or extreme terrain, it is a reliable tool that ensures accurate timekeeping in any condition.
Marathon Watch has a long history of supplying timepieces to military forces worldwide. With a focus on function over aesthetics, the OSAR-D reflects the brand’s commitment to quality and performance.
It is a watch that prioritizes practicality, legibility, and resilience, making it a trusted companion for those who require dependability in their gear.
Military-Grade Construction
The OSAR-D is built to withstand extreme environments. The case is made from 316L stainless steel, a material known for its resistance to corrosion, impact, and temperature fluctuations. Designed to meet the needs of military divers and rescue professionals, the watch has a water resistance rating of 300 meters, making it suitable for deep-sea operations.
With a 41mm case, it offers a balance between toughness and wearability. The unidirectional bezel allows for precise time tracking, a feature that is especially useful in dive missions. The screw-down crown and case back enhance protection against dust, water, and debris, ensuring the movement remains secure even in the harshest conditions.
Superior Legibility
A key feature of the OSAR-D is its legibility. The dial is designed to be read quickly, even in low-light environments. High-contrast numerals and bold hands provide clarity, while the inclusion of tritium gas tubes ensures visibility in complete darkness. Unlike traditional luminous coatings that require exposure to light, tritium tubes offer continuous illumination without fading.
The sapphire crystal covering the dial is scratch-resistant and treated with an anti-reflective coating, reducing glare and making the watch easy to read in bright sunlight. This makes it a practical choice for professionals who work in varying lighting conditions, whether underwater, at night, or in direct sunlight.
Swiss Precision for Reliable Timekeeping
The OSAR-D is powered by a Swiss-made Sellita SW200-1 automatic movement, known for its accuracy and durability. Unlike quartz watches that require batteries, an automatic movement harnesses the motion of the wearer’s wrist to keep the watch running. This ensures reliability even in remote locations where access to battery replacements may be limited.
With a power reserve of approximately 38 hours, the watch will continue running even if not worn for a day or two. The hacking seconds feature allows for precise time synchronization, a function that is especially valuable for military and tactical operations. For those who prefer minimal maintenance, a high-accuracy quartz version is also available.
Designed for Professionals
While the Marathon OSAR-D was originally designed for military and rescue operations, it has also gained popularity among civilians who require a durable and reliable timepiece. Its robust construction and practical design make it a suitable choice for a range of users.
- Divers and water sports enthusiasts benefit from its high water resistance and easy-to-read dial.
- Law enforcement officers and first responders appreciate the shock-resistant build and durable construction.
- Outdoor adventurers and hikers find it reliable in extreme conditions where other watches may fail.
- Collectors and watch enthusiasts value its military heritage and Swiss craftsmanship.
A Watch Built for Longevity
Unlike many modern smartwatches that require regular charging and software updates, the OSAR-D is designed to function independently for years. It does not rely on external power sources or digital connectivity, making it a long-term investment for those who prefer a mechanical or quartz alternative.
The combination of high-quality materials, precision engineering, and military-grade durability ensures that this watch will continue to perform reliably for decades. Its timeless design means it will never go out of style, and its functional features make it a practical tool for both professionals and everyday users.
Why the Marathon OSAR-D Stands Out
In a market filled with dive watches and tactical timepieces, the OSAR-D remains a standout due to its authentic military background and no-nonsense design. It is not just inspired by military specifications—it is built to meet them.
Marathon Watch has a long-standing reputation for producing watches that meet the needs of professionals who operate in extreme conditions. Every detail of the OSAR-D, from its legibility to its movement, is designed with purpose, making it a practical and reliable choice for those who require more than just a standard wristwatch.
A Timepiece That Goes Beyond Trends
The OSAR-D is more than just a watch; it is a tool for those who need precision and reliability in their daily lives. Whether used in tactical operations, outdoor adventures, or professional settings, it delivers performance without compromise.
For those seeking a watch that will not only withstand the test of time but also provide dependable functionality, the OSAR-D is an excellent choice. It offers a combination of military-grade durability, Swiss precision, and practical design that makes it one of the most reliable watches available today.
