Brand New Mainspring or Complete Barrel For Rolex Watch Service Parts Cal. 3130 3135 & Many More.
If you are having your watch serviced, do yourself a favour and change the mainspring as part of the service. If your watch does not yet need a service, keep a mainspring 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 power reserve. Brand new and sealed mainsprings or complete barrels (includes barrel, arbor and mainspring) for several Rolex automatic calibers. Swiss made. Manufactured from inox steel and ready to use as they are already greased. Choose from the list of calibers in the listing. Please note that I do not accept returns for parts.
Feel free to contact me for whatever questions you might have.
