One of the oldest surviving watchmaking brands, Blancpain was founded by Jehan-Jacques Blancpain in Villeret, Switzerland, in 1735. It has notably produced some of the most complicated mechanical watches ever made, appropriately named the Blancpain 1735 Grande Complication. The timepiece comprises almost every complication one can imagine: a minute repeater, perpetual calendar, split-seconds chronograph, moonphase, leap year, and a tourbillon escapement. Their portfolio also accounts for the first contemporary diving watch, The Fifty Fathoms, that was introduced in 1953.
