In the third lesson of his watch repair series, Alex Hamilton provides a comprehensive walkthrough of the keyless works using an ST-36 movement. He demonstrates the complete disassembly and reassembly of critical components, including the setting lever, winding pinion, and sliding pinion, while explaining their roles in winding and setting the watch. The tutorial offers practical advice on handling high-tension springs, identifying reverse-threaded screws, and using a “controlled release” to safely let down mainspring power. This lesson is a vital technical resource for understanding how the crown’s force is translated through the movement to control timekeeping functions.
