About depth readings
1. After switching to the Diving Mode, depth readings
will commence automatically when diving begins.
2. The depth will be measured and displayed in
1 metre (2.5ft) increments up to 50 metres (125ft).
Display in the Diving Mode
Please refer to the fold-out watch diagram located
on the opening page of this manual.
A – Depth indicator hand (function hand)
B – Points to DV
C – Minute hand
E – Hour hand
G – 24-hour time hand
F – Second hand
*If the hands A, B do not point to the correct position,
please readjust them according to the “ALL RESET”
instructions.
Reading the Depth
While diving, the number indicated by the depth
indicator hand A (the function hand) is the present
diving depth. The depth indicator hand begins to
function at a depth of 1 metre (2.5ft). It registers
depths of less than 1 metre (2.5ft) as 0. At depths of
over 50 metres (125ft), the hand stops on the over
Zone Mark (53 minutes) and remains there until
returning to depths less than 50 metres (125ft).
Measurements and Range
Display range: 0m (0ft) to 50m (125ft)
Display increment: 1 metre (2.5ft)
Measurement internal: Once/second
[Maximum depth memo function]
This watch automatically records the maximum
depth reached during a dive (in 1 metre (2.5ft)
increments). This memo is retained until the watch
is set to the Diving Mode again of 1 metre (2.5ft) or
more is reached.
Calling the maximum depth memo
1. While in the Time Mode or Diving
Mode (a depth of 0 is displayed)
press button
2
. The function hand A
will display the maximum depth.
2. Pressing button
2
a second time or leaving the
memo displayed continuously for 30 seconds will
release the maximum depth memo display.
Note:
1. A depth less than 1 metre (2.5ft) is not recorded.
2. The data in the maximum depth memo will be
cleared when the battery reaches the end of its life.
Be sure to record necessary memo information in
a log book.
3. The first time this function is used, it may display
data that was used in product testing.
4. Depths over 50 metres (125ft) will be recorded as
the Over Zone Mark.
Additional functions
<Auto return system>
The watch automatically returns to the Time Mode
if the function hand remains at 0 metre (0ft) for
longer than 30 minutes in the Diving Mode.
<Abnormal activation prevention function>
If the depth meter is functioning abnormally for
some reason, the function hand will point to the
Over Zone Mark when the watch is switched to
the Diving Mode, and depth measurement will
not be possible. In such a case, switch back to
the Time Mode.
[Making accurate depth readings]
1. Switch the watch to the Diving Mode shortly
before diving.
2. When there is a great difference between the
air and temperature, immerse the watch in the
water for 2-3 minutes before switching it to the
diving mode.
3. Confirm that the mode hand points to the DV
and the function hand points to 0 when the
watch is switched to the Diving Mode. If the
hands are in the wrong position please refer to
ALL RESET on page 23.
4. Avoid too rapid descents and ascents when
diving. The function hand will not adjust quickly
enough during descents or ascents faster than
about 1 metre (2.5ft) per minute. Slowdown or
stop in order to obtain an accurate depth
reading.
*Never pull out or turn the crown or press the
buttons while diving. Doing so may cause
water to penetrate the case.
[High altitude and freshwater diving]
When the Diving Mode is activated, the depth is
calibrated at 0 metre (0ft) based on the
surrounding air pressure. This enables the watch
to be used while diving at high-altitudes and/or in
lakes, as long as the Diving Mode is activated, at
that altitude.
However, an accurate measurement is not
possible at altitudes over 4,000 metres (13,124ft).
Do not use this watch when diving in such places.
Further, this watch displays changes in depth
based on a standard of seawater (density 1.025).
Depths indicated in fresh water will actually be
about 2.5% over indicated.
Be sure to complete appropriate safety training
before in fresh water or at high altitudes.
(Example) 20 metres (50ft) (indicated depth) x
1.025 = 20.5 metres (51.25ft) (actual depth).
