TAG Heuer Formula 1 Solargraph 38 Stainless Steel / White / Bracelet Ref. WBY111E.BA0042

The TAG Heuer Formula 1 Solargraph WBY111E.BA0042 is a 38 mm solar-powered quartz watch combining a sandblasted stainless steel case and bracelet with a white opaline dial and green TH-Polylight bezel. The case measures 38 mm in diameter and 9.9 mm in thickness, with a lug width of 18.5 mm. It is fitted with a rotating green bezel made from TH-Polylight, a polyamide-based material used by TAG Heuer. A steel crown and solid steel case back complete the construction, while water resistance is rated to 100 meters. The white opaline dial features applied hour markers and a central display for the hours, minutes and seconds. A date aperture is incorporated into the layout. Power comes from TAG Heuer Calibre TH50-00, a solar quartz movement charged by natural or artificial light. A full charge provides up to ten months of autonomy, while brief exposure to light can generate sufficient energy for approximately one day of operation. TAG Heuer states a battery lifespan of up to 15 years. The sandblasted stainless steel bracelet is secured by a folding clasp with a double-safety system.
