My swiss Elgin watch is 40 + years old and it had never been serviced. I recently took it out of the drawer and started wearing it and after a few days realized that it was not self-winding. Sent it to MJR and explained that it probably just needed serviced. It had only been gone from my house about 18 days total and today it is back in my hands working like new again. The 18 days includes my shipping time and their shipping time to return it plus their time to repair it. All in all that is super-fast! Very happy with MJR service and will always use them from now on. Thanks a million!
