this is a beautiful vacheron constantin dresswatch, reference 7401 from the early 1970s in 18k yellowgold, that is powered by the k1120 automatic caliber. this iconic and most exclusive automatic caliber in the watchworld is a VC finished JLC 920, which is also being used by Patek Philippe and Audemars Piguet for their Nautilus and Royal Oaks. No other brand than those three has ever been allowed to use this movement. the watch is in absolute mint condition with a flawless dial and handset. the 33m case with integrated goldbracelet currently fits wrists up to a size of 17,5 cm circumference and can also easily be shortened about a level over the clasp. the caliber k1120 with seal of geneva runs exactly and is not in the need for a service.
