Wristwatch restoration, servicing and repair

Seiko 6602-9982…

A manual wind dress watch from the Sportsman range came my way, this one dating to 1968. The only signs of age being wear on the crown.

Despite its great cosmetic condition, it did have one problem. When setting the time, only the hour hand moved. Further investigation revealed a cannon pinion that had been tightened incorrectly resulting in it gradually riding up during time setting, eventually losing contact with the minute wheel.

An easy fix, the crimp in the cannon pinion is pressed out from the inside and repunched in the right place. A great looking result.
