My favourite watchmaker the oldest in continuous activity since 1755.
This is a full set VC patrimony 33003 from 1983 with the Cal. 1003 signed with the Geneva seal :-)! The 1003 remains the world's thinnest traditionally constructed watch movement ever produced to date at 1.64mm high and 20.80mm in diameter! The Vacheron Constantin calibre 1003 was developed by Audemars Piguet together with JLC based on the Cal. 849 but the VC has a thickness of 1.64mm versus 1.85 mm for JLC!

This is for a recase project, a beautiful Vacheron Constantin caliber K1001/2 with the Geneva seal (Poinçon de Genève) 17 jewels (based on a JLC 818) from the 1960's. This VC caliber was part of a ref. 6456 (see pictures).
Some vintage VC have no Swiss mark, this dial has a "Beyeler Geneve" mark behind which certify the authenticity.

This is a nice recased VC Phidias automatic from the 90's with a VC Cal. 1130 (Frédéric Piguet. Caliber 9.51). I owned this watch when younger, it is not anymore part of the current collection.
