Round Stop Clock

This round laboratory stop clock features a stove-enamelled finish and two sweep hands: one indicating seconds and the other recording minutes. A start/stop lever is located on the left-hand side, and a zero reset lever on the right-hand side. The movement is housed in a metal case and runs for 24 hours on a single winding. The robust construction makes this stop clock suitable for laboratory timing applications in physics and chemistry classrooms where reliable, mechanical timekeeping is preferred.
