To wind the watch, release the screwed-in
crown (H) by turning it counterclockwise and
thus moving it to position 1. Then turn the
crown through approximately 40 clockwise
rotations to wind the watch up fully. Stop
winding the watch as soon as you feel any
WINDING THE WATCH
Pull the crown (H) out to position 3 to set the
time, which stops the movement. Turn the
crown in the appropriate direction so that the
hands (C and F) show the time required.
In months with fewer than 31 days, manual
adjustment of the date is necessary. To do
so, pull out the crown (H) to position 2. Set
the date (E) by turning the crown clockwise.
Then push the crown back into

The power-reserve indicator (B) shows how
far your movement is currently wound. If the
hand is pointing at 4/4, the movement is fully
wound. When the watch is running,For

hand is pointing to the shaded area between
1/4 and 0, your watch needs to be wound
manually using the crown.

FUNCTION AND USE OF THE DEPTH GAUGE
Your Raider Bathy 120 MemoDepth
can indicate a diving depth of up to 120
meters. Water enters a separate chamber
in the watch through a perforation in the
housing. Here it comes in contact with a
membrane that is temporarily deformed as
a result of the increasing water pressure. A
mechanical contact sensor inside the watch
reacts to the deformation and transmits
this information to the hands via a gear
mechanism. The depth of up to 120 m
is read off using the central pointer on a
linear scale on the outer edge of the dial. A
fine scale allows a detailed reading for the
first 30 metres of depth. Two red markings
between 3 and 6, and between 9 and 12
markings on the outer edge of the dial also
indicate to the diver the most important
decompression areas during ascent.
The precision of the depth measurement
display can vary by ±1 m and - from a depth
of 20 m - by ±5%. Changes in ambient air
pressure, temperature, general weather
conditions and altitude above sea level may
also affect the accuracy of the depth gauge.
For example:
- The blue center hand can indicate
between 11 m and 13 m when the dive
depth is 12 m.
- When diving to a depth of 40 m, the
displayed depth may be between 38 m
and 42 m.
- if you dive in Lake Titicaca situated
at 3812 m above sea level, the altitude
and surrounding air pressure results in a
difference of approximately -2 m before
the dive.
Such differences must be included in the
displayed dive depth.
* We suggest that you use the Bathy 120 MemoDepth
only as a complementary mechanical depth gauge, in
addition to your usual diving instruments.
resistance. Then screw in the crown again
by pressing and simultaneously turning it
clockwise to position 0.
Then push the crown back into position 0.
If the hour hand (C) moves past midnight
(24.00) when setting the time, the date
display (E) jumps forward by one.
position 0. You should not carry out any
quick adjustment of the date between
8.00 p.m. and 2.00 a.m., as the date is
automatically being turned on by the
movement during this time.
READING THE MAXIMUM DEPTH (MEMO DEPTH)
The Raider Bathy 120 MemoDepth has a
memory function. The sub-dial (J) shows
the maximum depth you have reached
during your dive. As the depth increases the
small blue pointer rotates in parallel to the
blue center pointer (K). A gear mechanism
designed ensures that the pointer on the
auxiliary dial (J) stops at the maximum diving
depth so that this maximum diving depth
can be reliably read off on a graduated
scale. Once the dive is completed and
the diver has resurfaced and read this
information from the auxiliary dial, the pointer
can be reset to zero by means of a screwed
pusher (I).
USE OF THE ROTATING BEZEL
Before starting a dive, set the zero marking
of the rotating bezel (G) to the position of the
minute hand (F). By doing this, you can see
how much diving time has elapsed while you
are diving. For safety reasons, the bezel
can only be rotated counterclockwise. If the
rotating bezel is turned accidentally during
a dive, this means that a longer diving time
is always shown. This reduces the risk of
accident.
