Carrera Chronograph Tourbillon Extreme Sport TH-Carbonspring

The TAG Heuer Carrera Chronograph Tourbillon Extreme Sport TH-Carbonspring CBU5091.FT6305 debuted in 2025 as a limited edition of 50 pieces. It showcases the TH-Carbonspring, the brand’s proprietary monobloc carbon hairspring designed to enhance chronometric stability through resistance to shocks, magnetic fields, and temperature changes. The case is forged carbon, 44mm in diameter and 15.4mm thick, paired with a black forged carbon tachymeter bezel. It is fitted with a domed sapphire crystal and a DLC-coated titanium case back with commemorative engraving. Water resistance is 100 meters. The dial is forged carbon with spiral engraving to echo the hairspring technology. Chronograph counters are placed at 3 and 9 o’clock, while the flying tourbillon is positioned at 6 o’clock within a black-gold ring. Black-gold faceted hands with Super-LumiNova indicate the time, with a central white lacquered chronograph seconds hand. The watch is powered by the automatic caliber TH20-61, a COSC-certified chronograph movement with tourbillon and the TH-Carbonspring. It beats at 28,800 vph and offers a 65-hour power reserve. Functions include hours, minutes, central chronograph seconds, 30-minute counter, 12-hour counter, and tourbillon. The strap is black rubber, fastened by a DLC-coated grade 2 titanium folding clasp.
