A 1960 Vacheron Constantin ref. 4667 in 18k rose gold is pretty much mid-century dress watchmaking at its most refined, from the era that would go on to define the modern Patrimony collection. The slim three-body case was made by Eggly & Cie, one of Geneva’s most respected casemakers, and remains sharp with crisp lines and deep mall marks. Inside beats the manually wound caliber K1001, running strong.
