The new TAG Heuer Formula 1 has grown from its original 35mm case size into a refined 38mm case that measures 45.2mm lug-to-lug, but is only 9.9mm thick.

At $1,800 (£1,650), the Formula 1 Solargraph is more than $1,000 cheaper than the basic Aquaracer Solargraph, and now by some distance the most affordable watch in TAG Heuer’s lineup.
