Powered by a Swiss quartz chronograph movement, the CAZ101AF.BA0637 delivers precise timekeeping with a 1/10th-second chronograph, central chronograph seconds, and a 30-minute counter. The sunray-brushed anthracite dial is accented by bold black chronograph registers and luminous hands and markers for enhanced legibility. Diagonal racing-inspired counters and contrast details evoke the speed and precision of track timekeeping. (tagheuer.com)

The 43 mm stainless steel case remains robust with a fixed tachymeter bezel and a sapphire crystal protecting the dial. Designed for an active lifestyle, the watch is rated to 200 m / 20 bar water resistance, making it suitable for swimming and most water sports. A three-row stainless steel bracelet with folding clasp completes the sporty yet refined look. This chronograph is part of the Formula 1 Senna lineup, celebrating one of racing’s most iconic figures. The reference has seen limited availability and is now discontinued on the official TAG Heuer online boutique. (tagheuer.com)
