In 1888 Cartier created the first ladies' wristwatches. It took until 1911 until the first gents’ watch, the Santos Dumont, came onto the market. The early Cartier wristwatches were all handmade in France. Cartier had a substantial influence in persuading the Parisian aristocracy to accept the idea of wristwatches for men; the classic pocket watch was considered the only timepiece a gentleman should carry. Louis Cartier undeniably laid the foundations of a new concept in luxury goods. The Tank is one of the most famous models in the Cartier line-up – the original Tank entered full production in 1919 and is still in production to this day. It was inspired by the new Renault tanks seen on the Western Front in WW1. Over the years is has graced the wrists of many notable individuals, among them JFK, Mohammed Ali, Princess Diana and Andy Warhol.
