Manual Mechanical Design
Designed as a precision analog stop-clock (also called stop‑clock), it operates with manual wind-up mechanisms featuring separate start/stop and reset functions.

Clear Analog Dial
Features a large circular dial (approximately 100 mm in diameter) with graduations in seconds and numbered at every five-second mark. Dual hands indicate seconds and minutes.

Simple and Reliable Operation
A start/stop lever allows precise control over timing, while a reset lever (or fly-back function) returns the hands instantly to zero for fast measurement cycles.
