Automatic ETA Calibers Are Listed Separately In The Store
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 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 complete mainsprings for ETA manual-wind calibers, Swiss made. Choose from the list of calibers in the listing. Please note that I do not accept returns for parts.
