TRITIUM GAS TUBES
CONSTANT ILLUMINATION
The JDD uses self-contained tritium gas tubes to ensure constant
visibility in low light situations. A gas tube is placed on each hour marker
and hand. These tubes are self-illuminating and contain an isotope of
hydrogen, that will not dull down over time like photo-luminescent paint.
WATER RESISTANCE
30 ATM – 300 M (1000 FT)
The JDD is made from 316L surgical-grade stainless-steel with a screw-
down crown and a synthetic sapphire crystal that allow it to operate while
submerged down to 300 meters or 1000 feet underwater.

BILINGUAL DAY INDICATOR
RAPID DAY DATE CORRECTION
The JDD is designed to display the day of the week in one of two
languages. Once the desired language has been set, the selected
language will automatically be maintained.
SWISS CRAFTMANSHIP
LA CHAUX-DE-FONDS, SWITZERLAND
Inside the JDD automatic is a Swiss-made, 26 jewels Sellita SW220
with Incabloc™Shock Absorber. These watches are hand-assembled
in La Chaux-de-Fonds, Switzerland and guarantee the highest level of
craftsmanship and accuracy.

1. Priming the movement.
Your JDD is charged via the movement of your wrist. Out of the box, gently
move your watch back and forth to charge up the movement. Avoid hand-winding
where necessary, as this could cause damage to the movement.
2. Clean watch often.
Clean regularly using rubbing alcohol, a toothbrush and a microbre cloth.
GENERAL OPERATIONS & MAINTENANCE 3. Always set it forward.
During events such as daylight-savings, you might be inclined to wind your
watch back an hour, however this can put undue stress on the movement of your
watch. Always move the hands forward to reach your desired time setting.
4. Service regularly.
Regular servicing every four to six years will help to keep your movement
running with Marathon-level precision. For servicing requests, contact our team
directly at [email protected]

1234SETTING THE TIME
1. Unscrew and pull the crown from position 1 to position 4.
2. Turn the crown clockwise to adjust the time.
3. Ensure correct AM/PM settings so that the date wheel changes
at midnight and not mid-day.

2341SETTING THE DAY & DATE
1. Unscrew and pull the crown from position 1 to position 3.
2. Turn the crown clockwise to change the date or counter-clockwise to change
the day.
CAUTION: Do not adjust the date wheel between 9pm and 3am as this may
damage the watch movement.

The crown must be screwed down in position 1 for optimal
water-resistance.
23 41LOCKING THE CROWN
From position 2, push the crown into position 1 and rotate clockwise to lock the
crown back into place.
NOTE: The JDD was designed to automatically hand-wind the watch while
screwing in the crown. Avoid hand-winding where necessary as this could cause
damage to the movement.

Rotate bezel counter-clockwise, aligning the 12 o'clock bezel
marker with the minute hand to set a starting time.
TIMING BEZEL
1. Rotate your bezel counter-clockwise and align the 12 o'clock bezel marker with
the minute hand. This will set your start time.
2. Measure the minute hand against the bezel markers to count the elapsed time.
NOTE: When diving, use your dive watch as a support device alongside the
recommended diving tools suggested by PADI or BSAC.
