Barrel Complete Service Replacement Swiss Made Part For BREILTING Watch Movement Cal. B01 – Brand New & Sealed

Brand new and sealed for Breitling watch movement caliber B01. Comes complete barrel with lid, arbor and mainspring. If you are having your watch serviced, do yourself a favour and change this as part of the service; it is 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. Please note that I do not accept returns for such parts. Feel free to contact me for whatever questions you might have.
