Bring professional-grade timing analysis to your workbench with the WeiShi No.1000/No.1900 timegrapher, a precise mechanical watch test instrument built for watch manufacturers, repair technicians and dedicated hobbyists. It measures how a movement actually performs, so you can regulate, diagnose and confirm results with confidence instead of guesswork.
The LCD screen displays the watch frequency diagram while the instrument automatically calculates rate deviation, amplitude and beat error, presenting everything as live data in real time. Whether you service watches daily or restore vintage pieces on weekends, this tester gives you the readings you need to fine-tune a movement accurately.

Place a running mechanical watch on the tester and let it analyse the movement. Use the readings to check timing accuracy before and after a service, to diagnose amplitude problems, or to verify a regulation adjustment. It is a practical tool for watch repair shops, restoration workshops and collectors who maintain their own mechanical timepieces.
