🔧 What it does & how to use

This is a quick diagnostic tool for anyone servicing quartz watches, from hobbyists to working watchmakers.

• Line release: switch this function on and the tester spins the watch hands at high speed. This confirms the gear train is turning freely and, on many stalled quartz watches, is enough on its own to clear trapped particles or gumming that's stopping the movement from running.
• Pulse test: checks that the electronic circuit board inside the movement is sending out a working pulse, helping you confirm the circuit itself is functioning before you look elsewhere.
• Cell test: touch the tester to a battery to quickly check whether it still holds power or needs replacing.
• ECB circuit test: a dedicated function for testing the circuit board.
• Demagnetiser: built into the same unit, for demagnetising movements and tools affected by stray magnetism.

Simply apply the relevant test function to the watch or component in question and read the result — a fast, practical way to narrow down why a quartz watch has stopped running before committing to a full service.
