Weishi Timegrapher 1000 1900 Watch Tester Calibrator

Experience precise timekeeping with the Weishi Timegrapher 1000/1900 — a compact, multifunctional watch tester and calibrator designed for professional use by watchmakers and technicians. This dual-model instrument delivers real-time data to help you evaluate rate deviation, amplitude, and beat error across multiple testing positions, making accurate calibration faster and easier.

This unit is available in two variants: No.1900 and No.1000. The No.1900 version features an LCD color display with automatic signal level adjustment for optimal testing across different movements, while the No.1000 version provides a robust metal build with precise numeric readouts. Please note that a regional logo variation may occur due to regulations, but the product remains 100% new and original apart from the logo.

Benefits & Tips

• Quickly verify mechanical watch accuracy by measuring rate deviation, amplitude, and beat error, with real-time data on a clear LCD or numeric readouts.
• Rely on automatic signal level optimization for various watches, and switch to manual beat adjustment when testing special beat conditions.
• Choose an appropriate sampling period (2–60 seconds) to balance speed and precision; averaging over longer periods yields the most stable results.
