Marathon x Jeep® 41mm Rubicon — Diver's Watch

Where the Willys field watches draw on the 1941 infantry supply history, the Rubicon series lands in a different category entirely: a full SAR-spec dive watch built to Canadian Government requirements, dressed with Jeep collaboration details. The case gets an engraved seven-slot Jeep grille on the side, a Willys star on the knurled screw-down crown, and a caseback engraved with Jeep's motto and the words "Since 1941." The dial runs the same Jeep Wrangler 1941 Limited Edition typography as the Willys, but adds a distinctive red-line indicator repurposed as a 15-minute count-up — a nod to Jeep dashboard instrumentation.  The case is 41mm 316L stainless steel, 14mm thick, 48mm lug-to-lug — the added bulk over the Willys is where the 300m water resistance and screw-down crown live. The oversized unidirectional dive bezel runs 60 minutes with 120 clicks and is fully hashed. Lighting is dual-system: tritium gas tubes for passive constant illumination and MaraGlo on the remaining handset and dial elements. Both variants include a sapphire crystal and ship with a 3-piece rubber strap kit in OD Green, with Black available as an option. The TSAR runs a Swiss-made ETA F06.412 HeavyDrive-PreciDrive quartz, rated to ±10 seconds per year — the same movement family as Marathon's standard TSAR line. The GSAR steps up to a Sellita SW200-1 automatic with Incabloc shock protection, 26 jewels, and a date complication shared across both calibers. The Incabloc is a meaningful addition here: a dive watch takes impacts, and having shock protection integrated into the movement rather than bolted on as an afterthought reflects the SAR design brief these watches are built to.
