How about a tourbillon made by one of the most famous tourbillon makers of all time? This pocket watch has a movement made by non other than Ernest Guinand, of Le Locle, who was after Breguet the most famous maker of tourbillons in the 19th century. His work included the creation of what was at the time, the smallest tourbillon anyone had ever made – a 14‴ (ligne) caliber (about 31.9mm) produced in 1876-1877, which would hold the record until 1927, when it was finally broken by the equally legendary James Pellaton (who subsequently had his record broken by one of his own apprentices, Fritz-Robert Charrue, in 1945, with a movement just 19.7mm in diameter). Guinand’s output of tourbillons included no. 1060 (his first) which was sold to Girard-Perregaux, and which when subsequently tested at the observatory at Neuchâtel, showed a daily gain on its rate of only 0.15 seconds and, rather miraculously, a temperature variation of zero seconds over the course of the testing period. In addition to GP, Guinand made tourbillons for other high-end clients as well, including Patek Philippe (whose first tourbillon ever, according to the lot notes, was made by Guinand).
