The TAG Heuer Formula 1 line has been the brand's sportiest and most accessible expression since its 1986 launch alongside the F1 World Championship sponsorship. Reference CAZ1011 is the classic quartz chronograph variant — a 43mm steel watch built for daily wear with motorsport-inspired styling.

The 43mm case is crafted from brushed stainless steel with polished bevels and carries a fixed black aluminium tachymeter bezel around a scratch-resistant sapphire crystal. A screw-down crown and chronograph pushers secure water resistance to 200 metres.

The anthracite dial displays three chronograph sub-dials — a 1/10-second counter at two o'clock, a running small seconds at six, and a 30-minute totaliser at ten — beneath applied luminous hour markers and baton hands filled with Super-LumiNova. A date aperture sits between four and five o'clock.

The Calibre Ronda 5040 is a high-accuracy Swiss quartz chronograph movement, offering 1/10-second resolution on the chronograph, a 30-minute cumulative timer, and a battery life of approximately four years.

Presented on a brushed stainless steel bracelet with polished centre links and a folding butterfly clasp with double security pushers.

Very good condition from 2025 means around a year of wear — expect moderate scratching on polished surfaces, dulling on brushed components, possible desk-diving marks on clasp, no significant damage. Complete as a full set with original box and papers dated October 2025. The two-year TAG Heuer manufacturer's warranty remains active until October 2027.

The Formula 1 Chronograph pairs TAG Heuer's motorsport heritage with Swiss quartz reliability — a sports watch built to be worn hard.
