We’ve utilised a ‘new-old-stock’ Valjoux 7734 movement from the 1960s in our limited edition Revival 1969 chronograph. Here are some interesting facts about this historic movement: 01. As the name of the watch suggests, the Valjoux 7734 was first produced 45 years ago, in 1969. 02. The name ‘Valjoux’ comes from the mountainous region in Switzerland called ‘Valley de Joux’ made famous for stopwatch and chronograph movements. 03. Watchmaking began in the Valley, when farmers would make clocks and watches on their farm tables in the bleak winters (When it was too cold to venture outside!). 04. The origins of the 7734 come from another chronograph manufacturer, Venus who made the ‘Venus 188’ but stopped operating in 1966. Valjoux took the designs for the 188 and adapted it into the Valjoux 7730. 05. The Valjoux 7734 is part of the series in the 7730 family. These come in different configurations, such as the 7736 with an extra hour counter. 06. Watch companies such as Breitling, Tudor and Heuer used the Valjoux 7734 during the 60s and 70s. 07. Production of the 7734 stopped after nine years in 1978 but was still continued to be used in mechanical watches into the 1980s. 08. The 7734 can also found with a rare moon phase caliber. 09. Being a handwound movement, once fully wound the 7734 will retain power for 45 hours. As it’s not automatic, there’s no rotor, so the full movement can be viewed at all times through an exhibition (glass) caseback. 10. The Valjoux 7734 operates at a slightly slower VBH (Vibrations per hour) than modern automatic movements. This means the ‘ticka ticka’ sound is pleasing and reminiscent with vintage watches and past times.
