M & I is a reliable outfit. To date, only battery replacement service has been necessary, but we do have an eclectic mix of quartz watches from Seiko, G-Shock and Timex. M & I has done a swell job in every case, and the cost of battery service is entirely fair--why not visit a specialist for this type of operation? When my Seiko pilot watch suddenly failed to operate a day after I visited M & I to have its battery replaced, the watchmaker patiently took it apart, installed another new battery and got it going again, no questions asked. I trust this shop to follow through professionally.
