TO PRESERVE THE QUALITY OF YOUR WATCH
If "WATER RESISTANT" is not inscribed on the case back, your watch is not water resistant, and care should be taken not to get it wet as water may damage the movement. If the watch becomes wet, we suggest that you have it checked by an AUTHORISED SEIKO DEALER or SERVICE CENTRE.
Water resistance (3 bar)
If "WATER RESISTANT" is inscribed on the case back, your watch is designed and manufactured to withstand up to 3 bar, such as accidental contact with splashes of water or rain, but it is not designed for wearing while swimming or diving.
Water resistance (5 bar)*
If "WATER RESISTANT 5 BAR" is inscribed on the case back, your watch is designed and manufactured to withstand up to 5 bar and is suitable for wearing while swimming, yachting and taking a shower.
Water resistance (10 bar/15 bar /20 bar)*
If "WATER RESISTANT 10 BAR", "WATER RESISTANT 15 BAR" or "WATER RESISTANT 20 BAR" is inscribed on the case back, your watch is designed and manufactured to withstand up to 10 bar/15 bar/20 bar, respectively, and is suitable for wearing while taking a bath or shallow diving, but not for scuba diving.
We recommend that you wear a SEIKO Diver's watch while scuba diving.
* Before using a water resistant 5, 10, 15 or 20 bar watch in water, make sure the crown is pushed in completely. Do not operate the crown when the watch is wet or in water. If used in sea water, rinse the watch in fresh water and dry it completely.
* When taking a shower while wearing a water resistant 5 bar watch, or taking a bath while wearing a water resistant 10,15 or 20 bar watch, make sure to observe the following:
- Do not operate the crown when the watch is wet with soapy water or shampoo.
- If the watch is left in warm water, a slight time loss or gain may be caused.
This condition, however, will be corrected when the watch returns to normal temperature.
NOTE: Pressure in bar is a test pressure and should not be considered as corresponding to an actual diving depth since swimming movements tend to increase the pressure at a given depth. Care should also be taken when wearing and diving into water.
TEMPERATURE RANGE [for analogue quartz watches only]
Your watch works with stable accuracy in a temperature range of 5°C and 35°C (41°F and 95°F). Temperatures over 60°C or 140°F (50°C or 122°F for some calibres) may cause battery leakage or shorten the battery life. Do not leave your watch in very low temperatures below -10°C or +14°F (-5°C or +23°F for some calibres) for a long time since the cold may cause a slight time loss or gain. However, the above conditions will be corrected when the watch returns to normal temperature.
SHOCKS & VIBRATION
General light activities will not affect your watch, but be careful not to drop your watch or hit it against hard surfaces, as this may cause damage.
The watch will be adversely affected by strong magnetism. Keep the watch away from close contact with magnetic objects. (In the case of a quartz watch, normal accuracy will return if the watch is moved away from the magnetic field.)
It is recommended that the watch be checked once every 2 to 3 years. Have your watch checked by an AUTHORISED SEIKO DEALER or SERVICE CENTRE to ensure that the case, crown, gasket and crystal seal remain intact.
CARE OF CASE AND BRACELET
To prevent possible rusting of the case and bracelet caused by dust, moisture and perspiration, wipe them periodically with a soft dry cloth.
Be careful not to expose the watch to solvents (e.g., alcohol and gasoline), mercury (e.g., from a broken thermometer), cosmetic sprays, detergents, adhesives or paints, as the case, bracelet, etc. may become discoloured, deteriorate or damaged.
PRECAUTION REGARDING CASE BACK PROTECTIVE FILM
If your watch has a protective film and/or a sticker on the case back, please remove it before use.
