Winding an Automatic Movement
To power up an automatic movement, flick the timepiece sideways to swing the rotor. When the timepiece is on your wrist, you 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. Avoid hand-winding if possible.
Winding a Hand-wound Movement
Unfasten crown and turn it clockwise until it resists turning.
Genesis/ Ascent models only: for hand-wound movements, a full wind takes about 50 turns after which the crown will resist turning, so you should start fastening after 40-45 turns to ensure you can fasten the crown completely.
Fastening & Unfastening Screw Down Crown
To unfasten, turn crown anticlockwise until it pops out.
To fasten, turn crown 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.
If your timepiece has an automatic movement other than the Miyota 90S5 or STP 1-11, 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.
Strap/ Buckle Changing
To avoid scratching the lugs, place adhesive tape over the area where the screwdriver is to be inserted.
Use a 1.6 mm slotted screwdriver. Turn anticlockwise to unscrew, and clockwise to screw in.
If unscrewed lug bars can't be removed by hand, use a blunt pin to push them out from the opposite side.
If bar is stuck when screwing or unscrewing, you've cross-threaded the screws. Turn back gently, ensure threads are engaged properly and try again. Don't use excessive force.
If your timepiece is fitted with spring bars, use a blunt pin to push and compress the spring bar from one side of the lug, then pull out the strap. To attach, compress one side of the bar using a spring bar tool or fingernails, then gently squeeze it in between the lugs.
To remove buckle, use a spring bar tool or correctly sized screwdriver as appropriate.
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.
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.
