WINDING THE MOVEMENT
To power up an automatic movement, flick the timepiece sideways to swing the rotor. When the timepiece is on your wrist, your arm movements will automatically wind the movement. Audible spinning of the rotor is normal.
Manual winding is usually not necessary but if you have to, unfasten crown to winding position and give it a few turns clockwise until the timepiece starts running.
OPERATING THE CROWN
If your timepiece has a screw-down crown, to unfasten, turn crown anticlockwise until it pops out. To fasten, turn it clockwise while pressing it against the case. If crown feels stuck, don't use force. Roll back slightly by turning anticlockwise, engage screw threads and try again.
Don't over-tighten the crown. There's no need to, and you risk damaging it if you do.
SETTING TIME & DATE
If your timepiece has an automatic movement other than the Miyota 9039, pull crown out to the second position to set the time. Otherwise, or If it has a manual winding movement, pull crown out to the first position to set the time.
Always pull gently. Don't pull too hard or jerk the crown, as you may damage the mechanism. If you have difficulty pulling it out it's probably because you haven't completely unfastened it; turn it further anticlockwise.
Don't set the date when your timepiece displays a time between 9 PM and 3 AM, to avoid unnecessary wear on the mechanism.
To set date, pull crown to the first position, turn it until the previous day's date appears, then pull it to the second position and advance the time until the date changes over.
REMOVING & INSTALLING STRAP
The strap is fitted to your timepiece using spring bars. To remove strap, use a blunt pin tool to push and compress the bar from one side of the lug, then pull out the strap gently. Be careful not to lose or break the spring bars, as you would need to buy replacement bars.
To install strap, compress one side of the bar using a spring bar tool, then gently squeeze it in between the lugs.
Don't wear or store your timepiece with the crown unfastened, and don't operate the crown when your timepiece is wet. After swimming, rinse it in fresh water.
Don't expose your timepiece to extremes of temperature or corrosive chemicals/ vapours, or wear it in hot soapy water, in hot pools, or around solvents such as petrol, as steam and vapour can penetrate the case and damage the internals.
Using any form of metal cleaner or polish on any part of your timepiece may remove a thin layer from its surface, and it wouldn't be possible to restore the surface to its original condition.
Don't place timepiece near loudspeakers, computers, mobile phones or refrigerators as these generate strong magnetic fields that may affect its precision.
REGULATION & SERVICING
You can allow your timepiece to gain or lose several seconds per day by placing in different positions when it's running. To lose several seconds, place it vertically with crown facing down or, to lose even more, with crown facing up. To gain seconds, place it flat with dial facing up.
The movement in your timepiece is capable of running for decades without too much maintenance. To ensure optimal condition, you can visit any watchmaker to have the movement serviced and gaskets changed every 5 years.
