Welcome
REACTOR watches were conceived,
designed and built to withstand the real
world of sport enthusiasts. We are very
proud of what we have accomplished
and we are excited to welcome you to
our ever-growing family.
While your REACTOR watch is built for
maximum durability, it should ALWAYS be
rinsed thoroughly after use in salt water.
Designed for the Water
Your REACTOR Heavy Water watch is
specially designed for regular use in
water, and the special side wings create
an air flow channel to allow water or
perspiration to drain or evaporate from
under the watch.
ALWAYS RINSE YOUR HEAVY WATER
WATCH THOROUGHLY IN FRESH WATER
AFTER USE IN SALT WATER!

Adjusting the Temp
With the watch in normal Time mode,
press B3 to see the current air or water
temperature. The temperature sensor
is located on the right side of the watch
between B3 and B4, and reads the temp
when B3 is pressed.
Due to its location, the temp reading can
be influenced by body heat, so an offset
feature has been added to correct for
this effect. You will see the offset
function as the final step of the time
set procedure. To determine the offset,
wear the watch in a room of known
temperature for at least 15 minutes.
Press B3 to read the temp, then compare
to the known temperature of the room.
Determine the offset by subtracting the
displayed value from the known temp,
and enter the result into the offset field.
For most accurate water temp readings,
the offset value should be left at zero.

Although your watch has 100-lap
memory, this memory can only be
divided into nine segments (RUNs 1-9).
Once all nine segments are used (even
if lap memory is still free), saving an

recording the new segment as RUN 9.
