Knot PX82 Auto Charge Sport Watch
User Guide
The watch continues to work simply by wearing and using it normally (wrist
movement). It can store up to six months of charge,which is used to power the
watch. The watch can therefore be used without having to worry about battery
replacement.
It is recommended to wear the watch on your wrist for a constant and stable
charge.
Using the Power Reserve Indicator
You can check the level of residual charge by pressing the button at the two o’clock position and looking at the second hand. Look at the second hand’s current position, then press the button. The second hand will accelerate forwards, and you can see how much power remains by how far it moves.
- The charge level can be checked twice in a row, with two accelerations. When performing this check, only take one of the accelerations into account. To check the charge level a third time, press the button after the second hand has returned to its normal operating position.
- If the charge level is checked immediately after shaking the watch, the indicated level may be a little high. In this case, please check again after 10-15 minutes.
Charge Levels
Residual charge conservation
In order to conserve power, the hands may stop moving automatically if the
watch is left unattended for a certain period of time, even if there is
residual charge.
The amount of time before the hand stops moving depends on the amount of
residual charge. For more information, please refer to the table below.
Quick Start
The residual charge conservation function means that it remains possible to
perform a Quick Start (1-2 shakes to start normal operation) for approximately
180 days.
Theoretical values when left completely unattended from 100% residual charge
(reference values).
Caution
- If the second hand is moving at 2-second intervals, it means the charge is low. Once 180 days have elapsed after this signal, the charge will be exhausted and it will no longer be possible to perform a Quick Start.
- In the following cases, the repair will be subject to payment even if it is within the warranty period and the part is covered by the warranty.
- Malfunction or damage due to misuse or negligence.
- Malfunction or damage due to fire, flood, earthquake, or other natural disasters.
- Malfunction or damage due to improper repair or modification.
- Change in appearance that occurs during use (case, glass, minor scratches on the crown, etc.).
- The warranty card does not contain the dealer’s stamp and date of purchase, or it has been re-written.
- The warranty card is not presented.
- When repairing the watch, it may be necessary to replace the movement or use alternative parts for the case, dial, hands, glass, strap, etc.
- We promise to repair the product free of charge within the period and under the conditions specified in this document. This warranty does not affect your statutory rights.
How to Operate
Names of parts
Screw-locking crown
To prevent malfunction and improve water resistance, the crown can be screwed
in and locked when not in use.
- Unlock the crown to operate it.
- Lock the crown again when finished.
How to unlock the crown
Turn the crown counterclockwise.
This will loosen the crown, allowing it to be operated.
How to lock the crown
Turn the crown clockwise while lightly pressing it against the watch body,
until it stops.
Setting the time
Pull out the crown to position and rotate it to set the hours and minutes.
After the hours and minutes are set, push the crown back into its original
position to start the watch.
Setting the date
- Pull out the crown to position and rotate it to set the date.
- After the date is set, push the crown back into its original position to finish.
- Since the date changes between 21:00 and 01:00, the date should not be set during this timeframe.
Unidirectional bezel
In the diagram below, 30 minutes have elapsed since the bezel mark ( ) was
moved to the 10:10 position.
Measuring elapsed time
Rotate the bezel so that the mark ( ) is aligned with the minute hand.
After some time, the number that the minute hand points to on t he bezel will
indicate how much time has elapsed since the bezel was set.
Since the bezel is unidirectional, it can only be rotated counterclockwise.
Please do not try to force it to rotate in the clockwise direction.
Charging the Capacitor
There are two suggested ways to generate enough power for one day (24 hours).
- Shake the watch around 250 times
- Wear the watch for around 8 hours per day
Shaking the watch
To start the watch after it has stopped, shake the watch to generate power.
Shake the watch in the directions shown in the diagram. The sec ond hand will
start to move at 2-second intervals. After about 250 shakes back and forth,
there will be enough power for about 24 hours.
The charging is most effective if you swing the watch back and forth about twice per second at a width of about 20cm. Extremely fast and vigorous shaking will not result in efficient charging. You may be able to hear the sound of the generator running inside the watch; this is normal. An overcharge protection function means it is safe to continue to generate power even once it is fully charged.
Wearing the watch
By wearing the watch on your wrist as you move during daily life, power will
be generated naturally without having to deliberately shake the watch. To keep
the watch running continuously over a long period of time, it is recommended
to wear the watch five days per week (8 hours per day), as a guide.
Straps
Two-piece Type
The strap is fitted with an Easy Lever (see image below).Attach the short half
of the strap at the 12 o’clock side and the long half at the 6 o’clock side.
Turn the watch and strap upside down, then insert the strap into the watch
starting at the opposite side from the lever ①.
Push the lever inwards with your fingernail and slide the lever side of the strap (2) into he watch body too. Ensure the lever is properly inserted into the hole on both sides, then insert the other half of the strap in the same way. Take care not to damage the watch body when inserting the EasyLever into the hole.
Pull-through Type

Battery
This watch uses a special rechargeable battery which is different from
ordinary silver oxide batteries.Unlike disposable batteries such as dry cell
or button cell batteries, rechargeable batteries can be used repeatedly while
being charged and discharged. Depending on the operating environment, the
charging efficiency of the rechargeable battery may decrease over a long
period of time. In addition, with long-term use, the battery duration may
become shorter due to wear and dirt on the mechanical parts, and deterioration
of the lubricating oil. If there is a decline in performance, the watch should
be sent for repair.
Automatic overcharging prevention
Charging the battery beyond the time required for a full charge will not cause
any damage. When the rechargeable battery is fully charged, it is
automatically prevented from being overcharged.
Warning
- Do not remove the rechargeable battery.
- Replacing the rechargeable battery requires specialist expertise. Please refer to your watch dealer for assistance.
- If an ordinary silver oxide battery is used, it may rupture, overheat, or catch fire.
- When charging, do not place the watch too close to photographic lights, spotlights, incandescent lights etc., as this may cause the watch to become hot and damage the internal components.
- When charging using sunlight, do not place the watch on a car dashboard, as this may cause the watch to become very hot and lead to a malfunction.
- Do not allow the watch to exceed a temperature of 50°C.
Warranty
This watch is covered by the following warranty.
- For one year after purchase, if any fault should arise under normal use in accordance with the manual, the watch will be repaired or adjusted free of charge.
The part covered by the warranty is the watch body itself (the movement).
The rest of the watch is not covered by the warranty.
Magnetization
The watch uses a magnet in its ultra-compact step motor. If magnetized by a
cell phone, computer, television, hi-fi, speaker, electronic Mah Jongg table
or other electrical appliance or magnet, the watch may temporarily stop, lose
or gain time.
If this happens, the watch should be thoroughly inspected, adjusted and de-
magnetized. Magnetization is not covered by the warranty.
Original Knot Box
Please keep the original Knot box for your watch and strap in a safe place, so that it can be used when sending the watch for repair. The warranty will not cover any damage or malfunction that may arise when the watch is sent in a box other than the original Knot box. Thank you for your understanding.
