Remove the four knurled knobs, the cover and the sight glass
Fill the chamber with distilled water about halfway
Screw in (tighten) the pressure wheel fully until it stops to expel air from the system
Unscrew (loosen) the pressure knob fully
Repeat steps 3 & 4 to ensure that all air is expelled from the system

Pressure Testing A Watch
Insert the watch in
the pressure chamber.
Unscrew/retract the
pressure wheel completely until it stops.
Using the supplied
water bottle fully fill the pressure chamber
to the lip of the top with distilled water.
Replace the sight
glass eliminating as much of the air as possible.
Tilting the chamber slightly to the left while
installing the site glass may aid in eliminating
the air from the chamber. Replace top and
the four knurled knobs. DO NOT OVERTIGHTEN
THE KNOBS, as they will be difficult to remove
after the pressure test. Tighten the knobs
gently but evenly.
Tighten (clockwise)
the pressure wheel to the required test pressure
After the required
test time period, release the pressure by
unscrewing the pressure wheel until the gauge
reads "0".
Remove the four knurled
knobs, the cover and the sight glass. If the
sight glass is difficult to remove, apply
slight pressure to the system by turning the
pressure wheel clockwise until the glass is
free.
Remove the water using
the water bottle (by drawing the water up
into the bottle).
Remove the watch from
the tester. Warm the watch using
your preferred method and apply a drop of
cold water to the center of the crystal to
check for condensation inside the watch, per
standard industry practice.
