Before we repair your watch you will be quoted a price for the repair. If it turns out that we can not repair the watch to reasonable accuracy there will be no charge. Reasonable accuracy is within 1 to 1-1/2  minutes per day for an older mechanical watch, usually less than one minute per day, but this can vary depending on the watch movement. If you have an e-mail address please include it with your repair along with any other pertinent information about your watch.

Mail your watch to: 

Northern Partners
1017 Beechwood Dr.
Ludington, Mi 49431

If you decide not to have the watch repaired after receiving the quote there will be a $20.00 bench charge to help defray the cost of time and shipping.

Watch Notes

Most mechanical watches can be repaired with cleaning and oiling. We use the very best ultrasonic cleaner available. This machine cost nearly $1000.00. There are times when a mainspring needs replacement in addition to cleaning. When repairs go much beyond this a replacement movement is worth considering.
