Vacheron Constantin · Automatic

1120 AT/1

Vacheron Constantin's name for the Jaeger-LeCoultre 920, developed in 1967 and still the thinnest full-rotor automatic ever built at 2.45 mm. The same movement drove the three watches that created the luxury steel sports category — Vacheron's own 222, the Royal Oak and the Nautilus. Vacheron finishes it to Hallmark of Geneva standard and fits a 22-carat gold rotor.
