Operating instructions Natator 125 Description
3.4 Operating principle
The watch under test is placed in the tank
which has been filled with water (2). Once the
lid (1) is closed, the pressure can be progres-
sively increased by turning the hand wheel (4).
The tank’s internal pressure is indicated by the
pressure gauge (3).
Warning
The tank pressure can be increased up to a value which could destroy the watch!
Attention
Using the hand wheel it is possible to obtain a pressure greater than 125 bar. Never
exceed this value (risk of damage to the mechanical elements of the Natator 125).
Warning
Roxer does not guarantee the correct functioning of the device if the maximum pressure
(125 bar) has been exceeded.

4.3.2 Purge
Before first use, it is imperative to carry out a device purge. This operation permits removal of
any residual air within internal piping.
5When delivered, the hand wheel is screwed fully home and the notched ring is positioned to
reduce the pressure.
A. Open the lid (1).
B. Fill the tank with water (2).
Instruction
Do not close the lid.
C. Unscrew (6) the hand wheel (4) as far as it will go.
5To unscrew the hand wheel, the notched ring must first be turned in a clockwise direction (7).
Warning
Do not force the hand wheel once it is fully screwed out! Risk of severely damaging the device.
D. Screw in (5) the hand wheel (4) as far as it will go. Check that there are no air bubbles in the tank (3) .
5To screw in the hand wheel, the notched ring must first be turned in a counter-clockwise direction (8).
E. If bubbles appear, restart at point C. until they have completely disappeared.
5If problems occur, screw in the hand wheel as far as it will go, empty the tank and restart the
operation at point A. To empty the water out of the tank, follow the procedure on page 24.

Operating instructions Natator 125 Use
5Use
To test a watch using the Natator 125, carry out
the following operations:
5.1 Initial operations
A. Ensure that the hand wheel (5) is completely
unscrewed (6).
B. Place a watch (1) in the basket (2) and insert in
the tank (3).
C. Adjust the water level until the tank (3) floods.
5Ensure the water spills over slightly to make
sure the tank is completely full (the dropping
cup ensures any excess water is caught (4)).
5Use demineralised water to ensure no marks
are left on the watch after testing.
Warning
Do not force the hand wheel once it is fully screwed out ! Risk of severely damaging the
device.
D. Close the lid (7), pivot and screw in the locking
handle (8) while pressing the purge push-but-
ton (9).

Use
5.2 Increasing the pressure
A. Turn the notched ring (2) in a counter-clock-
wise direction until it “clicks”.
B. Turn the hand wheel (3) in a clockwise direc-
tion to increase the pressure to the required
value (1).
5The test can be carried out at any value
between 0 and 125 bar. It is not necessary to
increase the pressure up to the maximum
device pressure.
5If the required pressure is not reached,
decrease the pressure down to zero and repeat
the purge of the tank as explained on page 17.
Attention
Using the hand wheel you can obtain a
pressure greater than 125 bar. Never
exceed this value (risk of damage to the
mechanical elements).
Warning
Roxer does not guarantee the correct func-
tioning of the device if the maximum pres-
sure (125 bar) has been exceeded.
5If the force to be applied to the hand wheel is
too great, the handle (5) can be positioned as
indicated (4) in the adjoining figure. The pres-
sure can then be increased or reduced by back
and forth motion.
Warning
Do not force the hand wheel once it is fully
screwed out! Risk of severely damaging the
device.
