TAG Heuer goes all-in on the Monaco at Watches & Wonders 2026 — with two distinct takes on the iconic square case, one a refined evolution, the other a genuine mechanical revolution. Tim Mosso goes hands-on with both.

The Monaco Evergraph is the headline. Four years in the making at the TAG Heuer Lab, it introduces an entirely new chronograph control mechanism — the first genuinely new architecture since watchmakers chose between the column wheel and the lever-cam system in the 19th century. Traditional levers and springs are gone. In their place, two flexible bi-stable components produced via high-precision LIGA technology handle start, stop, and reset — delivering identical tactile feel from the first press to the ten-thousandth. The open-worked dial puts the new TH80-00 caliber — with its TH-Carbonspring oscillator — fully on display. Available in natural titanium with blue accents (a nod to Steve McQueen's 1133B) and black DLC with racing red highlights. COSC-certified, 70-hour power reserve.

The new Monaco Chronograph is the other side of the story — a return to the sharp, angular geometry of the original 1969 reference, now in a 40mm Grade 5 titanium case with the updated in-house TH20-11 caliber delivering 80 hours of power reserve. Available in Monaco blue, British racing green, and a two-tone titanium and 18k rose gold.
