"Vintage" has become common parlance when describing horological production today. According to some sources, the word originates in the Old French vendange (grape harvest) which came to refer to an exceptional year for wine. Others claim its etymology lies in the locution vingt ans d'âge which watchmakers use to refer to any timepiece older than two decades (twenty years of age). Given most Manufactures' venerable age, many of their iconic timepieces fall within this category of vintage, and bringing the past up-to-speed with the present has emerged as a major trend in watchmaking.
