The title’s bracelet-equipped Marathon Anthracite GSAR is reference WW194006BK-0109, not the separately sold rubber-strap package. Marathon lists a 41 mm case, 14 mm thickness, 48 mm lug-to-lug span, and 20 mm lug width, with an automatic Sellita SW200-1 movement and a 30 ATM rating. On Marathon’s North American site, the bracelet package was listed at $3,000 USD when checked on October 7, 2026; whether it is worth that price depends on your priorities, particularly the stealth finish, tritium lighting, and included bracelet.

Which Marathon Anthracite GSAR configuration is this?

Marathon sells two packages under the WW194006BK model family. The bracelet reference, WW194006BK-0109, is the configuration reviewed here. Its official product page lists an anthracite bracelet and a Marathon clasp option. An authorized Australian dealer describes its clasp as a butterfly clasp; because the descriptions differ, check the specific bracelet and clasp details with the seller before ordering. Marathon’s bracelet listing identifies the package and its specifications.

The separate WW194006BK-0130 package comes with a three-piece rubber strap kit and anthracite hardware; Marathon’s listing also shows a black 20 mm leather strap. The manufacturer describes this configuration as updated in 2026 with a black date wheel. It is not an accessory included with the bracelet reference. Marathon’s rubber-strap listing gives its package details.

Configuration Reference Included package North American listed price
Bracelet WW194006BK-0109 Anthracite bracelet $3,000 USD, listed October 7, 2026
Rubber strap WW194006BK-0130 Three-piece rubber strap kit with anthracite hardware $2,500 USD, listed October 7, 2026

These are the prices shown on Marathon’s North American product pages when accessed on October 7, 2026, not a guarantee of current price or availability. Both pages summarized two years of protection plus an extra year after registration; consult the current regional warranty terms and registration conditions for coverage details.

How large is the 41 mm Marathon GSAR?

Marathon lists the bracelet model at 41 mm in diameter, 14 mm thick, and 48 mm from lug to lug, with 20 mm between the lugs. The 48 mm span and 14 mm height are important alongside the headline diameter when estimating how the case may sit on your wrist. These are manufacturer dimensions, not a fit assessment for a particular wearer.

The 20 mm lug width allows consideration of other 20 mm straps, but width alone does not confirm a particular strap will fit well. Check its thickness, spring-bar compatibility, and hardware before buying. Marathon lists an anthracite three-piece rubber strap kit, nylon straps, and a Marathon x Bergeon spring-bar tool as extras on the bracelet page.

What movement is in the Anthracite GSAR, and how long is its power reserve?

Marathon specifies an Anthracite Sellita SW200-1 automatic movement with an Incabloc shock absorber and 26 jewels. It lists the watch’s date function but does not give a reserve figure on its product page. Authorized Australian dealer Suvretta describes the Sellita-based Marathon M2 automatic as beating at 28,800 beats per hour (4 Hz), with a typical 38-hour power reserve, hacking seconds, manual winding, and rapid date adjustment. Those are dealer-stated movement details, not independent measurements of this watch’s accuracy or reserve. The dealer places the date at 4:30 and describes both 12-hour and 24-hour dial markers. Suvretta’s listing provides its supplementary description.

What are the GSAR’s lighting and dive-watch specifications?

Marathon’s bracelet listing specifies tritium gas tubes and MaraGlo, a sapphire crystal, a screw-down crown, a unidirectional 60-minute bezel, and 30 ATM submersibility. The Australian dealer expresses the rating as 300 m / 1,000 ft and says the tritium tubes illuminate without needing to be charged by external light. A depth rating is a published specification, not a guarantee for every dive or operating condition; follow the manufacturer’s guidance for intended use.

The manufacturer’s origin account says the Anthracite GSAR was first issued in 2018 for stealth during tactical night missions. Marathon also says its broader Search and Rescue series was developed to Canadian Government requirements for professional SAR operations, introduced in the early 1990s, and used by members of Canadian and U.S. militaries. Those are company statements about the model and series, not independent confirmation of this specific watch’s deployment history.

Is the Marathon Anthracite GSAR worth it?

The bracelet package’s $3,000 USD North American listing places the decision on whether its particular specification and package match your needs. The case dimensions, automatic movement, tritium-and-MaraGlo lighting, and bracelet are the concrete points to weigh against your fit and budget preferences. The rubber package was listed at $2,500 USD, but it is a distinct reference with different included hardware, so compare the exact package rather than treating the prices as strap options on one SKU.

  • Exchangeable X Design: Take control of your style with our professional marine quartz watch featuring the revolutionary EXD (Exchangeable Lug Design) system – a reinforced 2.0 mm quick-change spring-pin mechanism with unmatched tensile strength of 400-500N (40-50kg), allowing effortless strap changes. Inspired by professional diving watches, but engineered for 21st-century versatility.
  • VH31 Sweep Second Quartz Movement: The VH31 movement delivers 4 pulses per second (ips), compared to only 1 pulse for standard quartz (60% smoother than Miyota 1L45). Furthermore, accuracy remains within ±15 seconds per month (far better than mechanical watches). More durable than delicate mechanical movements.
  • Sapphire Crystal Watch: Equipped with a flat sapphire crystal and a high-clarity AR coating for superior scratch protection and clarity. The anti-reflective coating improves readability in all lighting conditions, making it both functional and stylish.
  • BGW-9 Blue Super Luminous: The EXD men's watch features BGW-9 super luminous material on the dial, hands, and hour markers. The long-lasting blue glow ensures clear time readings in the dark—perfect for nighttime use, diving, or low-light environments.
  • 200-meter (20 ATM) water resistant: Our marine quartz watch is built to military standards for professional diving, water sports, and extreme conditions. Unlike ordinary "waterproof" watches, this model undergoes rigorous pressure testing to ensure flawless performance at depth—a true companion for divers.

The published specifications do not establish measured accuracy, wrist comfort, bezel feel, comparative lume brightness, durability, or tested underwater performance. If those qualities are decisive, seek evidence specific to the configuration and conditions you care about rather than inferring them from the specification sheet.
