PRESSURE TESTING WITH A WATCH
1.
Place the watch (with the crystal facing upwards) into the pressure chamber.
2.
Unscrew (loosen) the pressure wheel completely until it locks.
3.
Using the supplied water bottle, fully fill the pressure chamber to the top with distilled water until the water overflows through the trunking.
4.
- Replace the sight glass by eliminating the air as much as possible.
- Tilting the chamber slightly to the left while installing the sight glass, may help to expel air from the chamber.
- Replace the cover and screw in the 4 knurled knobs.
- Tighten the knobs firmly (opposite corners simultaneously).
- If the knobs are not tightened properly, they will be MORE difficult to remove after the test.
5.
- Tighten the pressure wheel (clockwise) to the required test pressure.
- The pressure should begin to rise almost immediately.
- If there is an air bubble in the chamber, it will be compressed as the pressure starts to rise.
- If the knurled knobs are not sufficiently or evenly tightened, water will leak from the pressure chamber.
- This will prevent the system from achieving the required pressure.
6.
After the test time required, release the pressure by unscrewing (loosening) the pressure wheel until the pressure gauge reads "0".
7.
- Remove the 4 knurled knobs, cover and sight glass.
- If the sight glass is difficult to remove, apply slight pressure into the system by turning the pressure wheel to the right until the glass is completely
free.
8.
Remove the water using the supplied water bottle : apply pressure to the empty bottle and insert the tube into the pressure chamber. Releasing
the pressure on the bottle, the water will be sucked in.
9.
Dry the watch using a dryer device and place a drop of water on the watch glass to check for condensation inside the watch, in accordance
with standard watchmaking industry practice.
