The Cartier Tank is one of the most iconic and instantly recognisable wristwatches in history. Designed in 1918 with the first watch being given as a gift to General Pershing commemorating the Victory which paved the way for the end of the war, the watch was put into production in 1919. According to legend, it was designed by Louis Cartier after he witnessed a Renault Tank rearing up over a trench during the war and was inspired by it’s footprint, with the tracks translating into the famous ‘brancards’ of the watch. This example made in the early 60s is known as an ‘extra plate’ or ultra-thin, and uses a movement ebauche made by Jaeger LeCoultre. The Patina: Cartier watches during the early 60s were considered pieces of fantastic rarity and opulence. There was a far more bespoke manner to the operations of the company and their timepieces were only offered to clientele of the highest standing. Each piece was made from solid 18ct gold and movement ebauches originated from some of the best manufactures of the period such as Jaeger LeCoultre. Dials were often made from fine enamel or lacquer. Sadly, over time, these dainty dress watches were often subjected to a careless impact or accidental fall which could result in the delicate dials being cracked. The patina in this picture is believed to be evidence of just such a misfortune. The construction of the watch can put pressure on the dial surface, which when combined with temperature fluctuations and humidity can cause polygonal, interconnecting networks of cracks known as tessellations.
