Watchmakers you need parts to be able to work, let the FTC know it now. Consumers you must be able to have your watch service/repair by the watchmaker of your choice at competitive price let the FTC know that immediately. Monopoly is against the law. Making you believe that only the restricting company is able to service/repair your watch is deceitful.

The FTC wants to hear from you, restricting companies are now entered in their computer system and will act when a pattern is detected. That will be achieve by sending your complaints, and let all people around you know about this.

Sent your complaint to:

Federal Trade Commission
Consumer Response Center
600 Pennsylvania Ave. NW
Washington, DC 20580.

Do you really Own your Watch?
This site represent personal opinion. When you purchased your watch, along with the warranty document was there a disclosure? A disclosure telling you that periodic service or any repair needed for the proper working of your watch can only be performed by that brand Service Center(s). That Service Center(s) reserve the right to decide for you what your watch needs and how much that Service/Repair will be. An estimate will be given to you with your choice to pay or pick-up your watch as is?

No, no such disclosure was given to you; however you will be subjected to the described policies. Companies by restricting the sale of the necessary replacement parts needed for the proper service/repair of your watch successfully monopolized the Service/Repair of their watches.Depending of the brand you purchased, you may not really own your watch. You are now at the mercy of that company and they didn’t even have the courtesy to let you know that!!
