TAG Heuer Monaco Evergraph Titanium / Blue Ref. CEW5181.FT8123

The TAG Heuer Monaco Evergraph CEW5181.FT8123 debuted in 2026 as a 40mm grade 5 titanium chronograph built around the new Calibre TH80-00. Within the Monaco line, this reference combines the collection’s revised square case profile with an open display architecture and a chronograph movement based on a compliant mechanism rather than the conventional system of levers and springs. Its case measures 40mm in diameter, 14.51mm in thickness, and 22.59mm between the lugs. The construction is executed in grade 5 titanium with fine-brushed, polished, and sand-blasted surfaces, and the fixed bezel is likewise in titanium. The watch is fitted with a beveled, domed sapphire crystal and a square sapphire caseback framed in grade 5 titanium. Water resistance is rated to 100 metres. The dial is transparent and built around the inverted architecture of the movement, with the barrel, gear train, balance, and escapement placed on the dial side. Blue opaline counters at 3 and 9 o’clock display the 30-minute chronograph register and running seconds respectively. The bridges are fine-brushed and sandblasted, while the applied indexes are filled with white Super-LumiNova. Open-worked rhodium-plated hour and minute hands are also filled with white Super-LumiNova and tipped in red lacquer, matched by a red lacquered central chronograph hand. Inside is the TAG Heuer Calibre TH80-00, an automatic chronograph movement with 47 jewels, operating at 36,000 vibrations per hour, or 5Hz, with a power reserve of 70 hours. It is COSC-certified and equipped with the TH-Carbonspring oscillator. Its chronograph mechanism is built around two flexible bistable components, one for start and stop and one for reset, produced using LIGA technology. This layout replaces the conventional lever-and-spring arrangement and forms the defining technical feature of the calibre. This reference is fitted on a blue rubber strap with a textile pattern and grey stitching, secured by a grade 5 titanium folding clasp with push-buttons.
