Mechanical Watch Characteristics (Hand-Wound, Auto-Wound) - Seiko 6R20 Instructions Manual

1
Please note that there is a risk of minor injury or material damage if the following safety
regulations are not strictly observed.
Avoid the following places for wearing or keeping the watch:
○ Places where volatile agents (cosmetics such as polish remover, bug repellent, thinners etc.) are
vaporizing
○ Places where the temperature drops below
5°C or rises above 35°C for a long time
○ Places affected by strong magnetism or static
electricity
If you observe any allergic symptoms or skin irritation
Stop wearing the watch immediately and consult a specialist such as a dermatologist or an allergist.
Other cautions
○ For adjusting the length of the metallic band, specialized knowledge and expertise are necessary.
Therefore, in such a case, contact the retailer from whom the watch was purchased. If you attempt
to adjust the metallic band, injury may occur to your hand or fingers, or parts of the band may be
lost.
○ Do not disassemble or tamper with the watch.
○ Keep the watch out of the reach of babies and children. Extra care should be taken to avoid risks
of any injury or allergic rash or itching that may be caused when you touch the watch.
○ If your watch is of the fob or pendant type, the strap or chain attached to the watch may damage
your clothes, or injure the hand, neck, or other parts of your body.

Please note that there is a risk of minor injury or material damage if the following safety
regulations are not strictly observed.
Do not turn or pull out the crown when the watch is wet.
Water may get inside of the watch.
* If the inner surface of the glass is clouded with condensation or water droplets appear
inside of the watch for a long time, the water resistant performance of the watch is
deteriorated. Immediately consult the retailer from whom the watch was purchased or
SEIKO CUSTOMER SERVICE CENTER.
Do not leave moisture, sweat and dirt on the watch for a long time.
Be aware of a risk that a water resistant watch may lessen its water resistant
performance because of deterioration of the adhesive on the glass or gasket, or
the development of rust on stainless steel.
Do not wear the watch while taking a bath or a sauna.
Steam, soap or some components of a hot spring may accelerate the
deterioration of water resistant performance of the watch.

b CAUTION
○ Places affected by strong vibrations
○ Places of high humidity
○ Dusty places
b CAUTION
b WARNING
Do not use the watch in scuba diving or saturation diving.
The various tightened inspections under simulated harsh environment, which are
usually required for watches designed for scuba diving or saturation diving, have
not been conducted on the water resistant watch with the BAR (barometric
pressure) display. For diving, use watches specifically designed for diving.
b CAUTION
Do not pour running water directly from faucet.
The water pressure of tap water from a faucet is high enough to degrade the water
resistant performance of a water resistant watch for everyday life.

Mechanical watch characteristics (Hand-wound, auto-wound)

• This is a mechanical watch powered by a spring.
• To use it from a stopped state, turn the crown 20 turns by hand to wind up the spring before starting the
watch.
• Although the accuracy of quartz watches is measured in differences over months or years, in mechanical
watches it is measured in differences per day (i.e., the amount the watch speeds up or slows down in a
single day).
• Additionally, mechanical watches are subtly affected by the conditions in which they are used (e.g.,
duration worn, temperature, arm movement, the amount wound, etc.) ; thus, the amount of error is not
constant.
• When affected by a strong magnetism from outside, a mechanical watch may lose/gain time temporarily.
The parts of the watch may become magnetized depending on the extent of the effect. In such a case,
consult the retailer from whom the watch was purchased since the watch requires repair including
demagnetizing.
