Pearl Apparatus Water Tightness Testing Machine
- The use of this tester is to put pressure on the watch to see if it can withstand it.
- The air will flow from high pressure areas to low pressure areas.
- When the chamber is pressurized if there are any leaks in the watch case the air will be drawn to this and you will be able to see these problematic areas when the machine is depressurized.
- A great mechanical addition for watchmakers repairs.
