Övrig information
In 1951, the Manufacture released the Futurematic, the world's first 100% automatic watch, the calibre 497, Calibre 497 debuted with the Jaeger-LeCoultre Futurematic and was much more advanced than the earlier JLC 476 and JLC 481. It features a larger balance for improved accuracy and hacking seconds. One unique feature is a lock that holds the swinging weight in place when the mainspring is fully wound. It also features a special 6 hour power reserve, allowing the watch to immediately function when it is put on, rather than requiring it to be wound first.
The Calibre 497 featured a power reserve indicator along with small seconds located at the unusual position of 3:00.
