About the 3LZF2
An automatic chronograph from Shanghai that follows the layout and dimensions of the Valjoux 7750: 30-minute and 12-hour counters, small seconds and day-date at 3 o’clock. It runs at 4 Hz with a 45-hour reserve, and brings the working character of a mechanical chronograph, with positive pushers and a sweeping centre seconds hand, to a Chinese-made movement.
