5 test samples

The test samples used in this test are. a) Comply with the travel time quality requirements in QB/T 1249 (real daily spread, instantaneous daily spread, temperature coefficient, continued travel time, comprehensive indicators, 6H swing, etc.) mechanical watch movement; b) Analog quartz watches that meet the travel time quality requirements of GB/T 6044 (average instantaneous daily difference, temperature coefficient, voltage coefficient, etc.) movement; c) Liquid crystal quartz watches that meet the travel time quality requirements (instantaneous daily difference, temperature coefficient, voltage coefficient, etc.) in GB/T 22780 movement. The watch movement should be fixed in a closed watch case similar to the final product for testing. The watch movement should be fixed on the watch through a fixed machine ring or other methods. on the casing, and ensure that there is a gap between the movement and the back cover in the direction of its axis. ......
