This TAG Heuer Formula 1 Solargraph limited edition timepiece offers a bold take on the collection's functional design. Crafted in sandblasted stainless steel, the 38 mm case and bracelet combine durability with everyday comfort. The pastel green dial is enhanced by 8 circular diamond-set indexes (0.076 ct, Color H, Clarity SI) and signature shield-shaped markers for excellent legibility. A bi-directional TH-Polylight bezel reinforces the timepiece's functional identity. Powered by the Solargraph Calibre TH50-00, it converts light into energy to deliver reliable precision and extended autonomy. The Solargraph Calibre TH50-00 is a quartz movement powered entirely by light. By converting both natural and artificial light into energy, it continuously recharges during everyday use. A full charge delivers up to 10 months of autonomy, while brief exposure to light can power the timepiece for a full day. Designed for durability, the movement offers a battery lifespan of up to 15 years, reducing maintenance while ensuring stable precision and dependable performance.
