Barometric Pressure Stability Testing for collectible watches

In the field of watchmaking, barometric pressure testing is an important indicator of a watch's stability and accuracy. Among them, the barometric pressure change test can simulate the effect of altitude change on watches, which is an essential part of watch quality inspection. In the watch market, in order to ensure the quality of collectible watches, it is also necessary to carry out strict air pressure change test.

Impact of air pressure

Barometric pressure is the force of atmospheric pressure per unit area, and therefore has a pressure difference between high pressure areas relative to low pressure areas. And the change of altitude will directly affect the change of air pressure, for example, for every 1,000 meters rise in altitude, the air pressure will drop about 10%. If the sealing of the watch can not be guaranteed, the change of air pressure will lead to the ingress of water, the entry of fog inside the watch, the loss of grease inside the watch and so on, which will make the watch's accuracy and stability decrease.

Air Pressure Change Test

Testing for changes in air pressure is usually done by placing the watch in an airtightness tester. The tester simulates an increase in altitude by reducing the ambient air pressure, and the difference in pressure inside the watch is measured. In the actual test, the watch is subjected to 12 hours of testing, during which time the air pressure changes eight times. After the watch passes the tester's airtightness test, if there are no abnormalities such as floating time or deceleration phenomena, the watch is well sealed and stable.

And collectible watches need to undergo a more stringent air pressure change test. It is tested in the same way as the genuine watches, which requires that the watches not only need to be stabilized in terms of airtightness, but also need to be close to the level of genuine watches in terms of time accuracy. Usually, collectible watches will undergo several air pressure change tests before passing the quality inspection.

concluding remarks

Barometric pressure change test is an essential part of watch manufacturing and quality inspection. In the collectible watches market, collectible watches ensure that the quality of the watches really meets the original standards through strict air pressure change tests. For consumers, choosing collectible watches can not only enjoy the wearing experience similar to that of the genuine ones, but also get a more affordable price.
