Brand New Mainspring Or Barrel Complete Watch Service Part For Jaeger LeCoultre JLC Caliber 481, 819, 822, 846.1, 889, 900, 916, K825, etc.
If you are having your watch serviced, do yourself a favour and change the mainspring as part of the service; the mainspring is probably one of the most important parts in a mechanical movement. If your watch does not yet need a service, keep one for future use, as these are getting harder and harder to find. You WILL need it at some point and it will greatly extend the life of your watch and also its accuracy. Brand new and sealed mainsprings for Jaeger LeCoultre calibers, Swiss made. This list contains both automatic and manual wind calibers, 3-handed watches and alarms and more calibers are added frequently. Choose from the list of calibers in the listing. Please note that I do not accept returns for parts.
