TAG Heuer Formula 1 Solargraph 38 Zandvoort Ref. WBY111H.FT8128

The TAG Heuer Formula 1 Solargraph Zandvoort WBY111H.FT8128 was introduced in 2026 as a limited edition of 1,500 pieces created to mark the final Dutch Grand Prix at Circuit Zandvoort. Its grey opaline dial is paired with orange and red accents, an orange TH-Polylight bezel and a matching rubber strap, referencing the orange color closely associated with the event and its spectators. The sandblasted stainless steel case measures 38 mm in diameter and is fitted with a flat sapphire crystal with anti-reflective treatment. An orange bidirectional bezel made from TH-Polylight carries a 60-minute scale, while a steel crown and screw-down case back complete the construction. Water resistance is rated to 100 meters. The grey opaline dial is surrounded by an orange and red minutes track. Red-lacquered applied markers are filled with eggshell-colored Super-LumiNova that emits green light in the dark. The hour and minute hands use the same red lacquer and luminous treatment, accompanied by a red central seconds hand. Shield-shaped markers at 6, 9 and 12 o’clock reference the design language of the original TAG Heuer Formula 1, while the date is positioned at 3 o’clock in a red-framed aperture. Power comes from TAG Heuer Calibre TH50-00, a solar quartz movement charged by natural or artificial light. One minute of direct sunlight provides approximately one day of operation, while a full charge, reached after less than 40 hours of light exposure, offers up to ten months of autonomy in darkness. If the movement stops, approximately ten seconds of light is sufficient to restart it. TAG Heuer states an accumulator lifespan of up to 15 years. The watch is fitted with an orange rubber strap and a steel pin buckle.
