HYQNG Watch Tester Waterproof 35x20x17 Tool 2 Watches Case Resistance Pressure Machine

Principle of Accurate Testing: This watch pressure tester simulates an environment of several dozen metres underwater by pressurising a sealed chamber; once the chamber is depressurised, a pressure differential forms between the inside and outside of the watch. If the watch is leaking, clearly visible bubbles will appear, enabling an accurate test of its water resistance. Simple and Intuitive Operation: Easy to use; during testing, if the pressure drops, observe whether bubbles form on the watch: the presence of bubbles indicates a poor seal, whilst the absence of bubbles indicates a good seal; once testing is complete, simply pull the lever to remove the watch – efficient and effortless. Wide Range of Applications: This tool efficiently tests a watch’s water resistance and is suitable for various settings, including homes and shops. Whether for routine self-checks by watch enthusiasts or professional testing in watch repair shops, it meets all usage requirements, making it a practical tool for water resistance testing. Transparent Cylinder for Easy Observation: The device features a transparent cylinder, allowing you to clearly see exactly which part of the watch is leaking during the test. This intuitive design enables rapid identification of leak points, enhancing both the efficiency and accuracy of the test. Thoughtful Design, Practical and Convenient:The overall design is tailored to user needs. The transparent cylinder facilitates observation, and the operating steps are simple and straightforward, requiring no complex calibration. Whether you are a novice or a professional, you can easily get to grips with it and efficiently complete the watch water resistance test.
