Vintage Vacheron Constantin Tonneau Case, Ref. 7813, Manual Wind Cal. K1014, 18K Solid Gold from 1970's

Vacheron Constantin needs no introduction - the oldest watch manufacture in continuous operation, and one of the "Holy Trinity" of Swiss watchmaking alongside Patek Philippe and Audemars Piguet. This reference 7813 is the brand at its most restrained: an 18K solid yellow gold tonneau case, 25mm x 35mm and just 7mm thick, with brushed surfaces and a softly curved profile that sits flat and discreet on the wrist.

The white dial is kept to essentials - applied gold baton markers with black inlay, doubled at twelve, slender black baton hands, and the Vacheron & Constantin Genève signature. Nothing else. The caseback carries the full set of confirmations: Swiss 18K 0.750 hallmarks, the Vacheron et Constantin signature, and reference number 7813, with case number 472037 on the outside.

Inside is the hand-wound Caliber K1014, a movement built on the Jaeger-LeCoultre 818 ébauche that was supplied exclusively to Vacheron Constantin and Audemars Piguet - and finished to the standard that implies. It is adjusted to heat, cold, isochronism, and five positions. The watch has been serviced and is running well.
