Housed in a round 43mm stainless steel case measuring 12.4mm thick, this Tag Heuer Formula 1 reference CAZ101AC.BA0842 centers on a black carbon fiber textured dial framed by a yellow flange marked with a 60-second/minute scale. The fixed ceramic bezel carries a tachymeter scale, while scratch-resistant sapphire crystal protects the dial beneath. Luminescent hands and index hour markers ensure legibility, with a yellow-tipped central seconds hand adding a motorsport-inspired accent.
The quartz chronograph movement drives a full suite of complications: a 1/10th-of-a-second counter sub-dial at 6 o'clock, a 30-minute counter sub-dial at 9 o'clock, and a small seconds sub-dial at 3 o'clock. A date window sits at the 4 o'clock position, and an end-of-battery-life indicator causes the seconds hand to jump every four seconds as a low-power alert.
The stainless steel bracelet secures with a folding clasp and complements the case finish throughout. This example is presented complete with its original box and original papers, making it a complete package for the collector or enthusiast drawn to Tag Heuer's Formula 1 lineup.
