Why it's interesting

TAG Heuer's 1986 Formula 1 was a colourful gateway into Swiss watches, and the 2025 revival keeps the spirit: the stepped 'décroché' case, shield-shaped markers and a red flange. It is now 38 mm, 9.9 mm thin and solar-powered — up to ten months on a full charge, with a battery rated for 15 years.

Watch DNA. Filled tags are editorial; outlined tags come from the specifications.
