WeiShi Timegrapher 1000 1900 Watch Testing Tool Repairers

The WeiShi Timegrapher 1000/1900 Watch Testing Tool is a precision mechanical watch testing instrument designed for professional watchmakers and repair technicians. Originating from Mainland China, it supports robust multi-testing to diagnose timing issues quickly and accurately. The No.1900/No.1000 models display the watch’s frequency diagram on a color LCD, automatically adjust signal levels for different watches, and compute rate deviation, amplitude, and beat error in real time. With six adjustable testing positions, selectable sampling periods from 2 to 60 seconds, and an optional be-at setup for conventional or special beat, this versatile tester helps you fine-tune timekeeping with confidence.

Key benefits

• Accurate timekeeping diagnostics: real-time rate deviation (up to ±999 s/d or ±99.9 s/d with 0.1 s/d resolution), amplitude (100°–360°, 1° resolution), and beat error (0.0–9.9 ms, 0.1 ms) for mechanical watches.
• Automated and flexible testing: automatic signal level adjustment, auto or manual beat handling, and multiple sampling periods (2/4/6/8/12/20/30/60 s) for precise results across different watch models.
• Comprehensive testing positions: six adjustable positions plus the option to simulate wear with either audible beeper or mute, ideal for both production and service environments.
