🔧 What it does & how to use

This tester runs a quartz movement's line release function, driving the hands round at speed far beyond normal running. It's a quick way to check the gear train is intact and to physically clear any trapped particles or gumming that's preventing the watch from running — often enough on its own to get a dead quartz watch going again, making it a handy first-check tool for hobbyists and a time-saver for busy workshops.

• Prepare the watch: take the case back off the watch first — the movement needs to sit exposed on the machine, not inside the closed case.
• Load the movement: place the watch (case back removed) onto the tester as intended for the machine.
• Run line release: activate the line release function and let the hands spin at speed.
• Check the result: a smooth, fast spin confirms the gear train is free; if hands were stuck or sluggish before, this often clears the fault.
• Reassemble: once testing is done, refit the case back before returning the watch to normal use.
