About this watch

Band: Blue Leather Clasp: Steel Pin Buckle (OEM) Glass: Sapphire crystal Water Resistant: 20 Bar (200 m) The connection between Heuer (TAG Heuer since 1985) and motorsport cannot be disputed. As the current timing partner for the 2026 Formula One season, Heuer’s racing association goes back even further to the early 1970s, when the legendary racer Jo Siffert gifted Steve McQueen racing overalls with a Heuer patch stitched on them. This account, however, varies depending on whom you ask. Don Nunley, the property master for the film Le Mans, suggested that Steve McQueen had already chosen a Heuer-patched white Nomex racing suit. Either way, a Heuer was worn in the 1971 commercial flop Le Mans, which later became a cult movie classic. The brushed and polished stainless-steel case measures 43 mm with a lug-to-lug of 48 mm, a lug width of 21 mm, and a depth of just 12 mm. Rated to a pressure of 20 bar, the watch is capable of immersion on paper. Due to the chronograph (stopwatch) pushers at 2 and 4, the watch has additional points of water ingress that can lead to a costly overhaul. The dial features a tri-compax layout in the Gulf Oil colourway: powder blue and orange. There is a running seconds subdial at 3, a 12-hour totalizer at 9, and a tenth-of-a-second subdial at 6, allowing for extremely accurate timing. There is a date aperture at 4 and a printed TAG Heuer logo at 12. The sword-shaped steel hands and faceted steel hour markers are filled with Super-LumiNova, a phosphorescent material that glows green, aiding low-light legibility. Protecting the hands is a scratch- and glare-resistant, man-made sapphire crystal offering durability and clarity thanks to sapphire’s inherent strength and an anti-reflective (AR) treatment.
