The Tissot PRX Chrono combines a historic 1978 case aesthetic with modern watchmaking technology. It features a distinct 42 mm 316L stainless steel case housing a blue gradient dial with contrasting sub-dials and a white date window.

Powered by the Swiss automatic Valjoux A05.H31 caliber, the watch delivers a classic 3, 6, and 9 chronograph layout and a power reserve of up to 68 hours. It incorporates a patented Nivachron balance spring for enhanced magnetic field resistance and Super-LumiNova coated hands and indices for low-light visibility.

A sapphire crystal with an anti-reflective bottom coating protects the dial, while a see-through case back reveals the movement inside. The watch is fitted with an interchangeable quick-release stainless steel bracelet secured by a butterfly clasp with push-buttons.
