AUTOMATED CHAMBER FOR TESTING THE WATERPROOFNESS OF THE WATCH

An automated pressure chamber for testing the waterproofness of wristwatches was designed and built. Water resistance refers to the watch’s ability to protect its internal mechanism from the ingress of water, moisture or other liquids that could cause damage or dysfunction to the watch. Smaller pressure chambers use an ordinary manual pneumatic cylinder to achieve a test pressure of up to a maximum of 6 bar, while pressure chambers in the production of luxury watches use test chambers up to 100 bar and can accommodate up to 30 watches. The manufactured device has a lower price, simpler construction and smaller dimensions than commercially available devices, and it can be used to test the waterproofness of a watch at higher pressures. On the built-in screen, the device has the option of selecting the pressure in the test chamber and the test time. The MIT App Inventor program was used to create the Android application, which uses blocks instead of coding, making it accessible to a wide range of users.
