Even when the watch falls into such condition, it still displays the time but the EL light, thermometer and alarm will not function.

  • Page 29: All Reset

    All reset After replacement of the battery, be sure to perform the all reset operation as shown below. If the watch malfunctions or shows an abnormal display as a result of an excessive shock or static electricity (for example, the watch indicates nothing, continuously sounds alarm, etc.).

  • Page 30: Using The Bezel

    Using the bezel Some watches do not have the following bezel functions because of differences in type or design. 1. Compass function 2. Yachting function 1. Compass function (in the northern hemisphere) Compass direction can be approximated by this function, based on the direction of the sun.
  • Page 31 Using the bezel 2. Yachting function <Background knowledge> Wind Windward mark In general yacht racing, such markings as shown in the figure are set in the course. Yachtsmen compete in how fast they can sail the course in the specified order. Sailing directions are specified by angles such as north Side mark = 0°, east = 90°, south = 180°, west = 270°.
  • Page 32 Using the bezel (2) The course toward the side mark from the windward mark (starboard reach) is in the direction of the green “ ▲ ” mark located in the lower left side. Therefore, sail in this direction so that the yacht reaches the side mark even when the mark is hard to find because of bad weather.
  • Page 33 Using the bezel <Using bezel-2> The yacht can sail in the windward direction Wind at an angle of 45° (high performance yacht can sail 40°). If the yacht is sailed in the windward direction before race and the obtained angle at the red or green mark (upper right or upper left) is set, the wind shift can be read during the race.
  • Page 34 Using the bezel <Using bezel-3> The bezel can be used to find the angle of the start Direction of wind line to the wind direction. The start line is generally set to the wind at an angle of 90°. However, it seldom is the real right angle because the wind direction changes frequently.

  • Page 35: Water Resistance

    Water resistance WARNING Water Resistance • Non-water resistant models are not designed to come into contact with any moisture. Take care not to expose a watch with this rating to any type of moisture. • Water resistance for daily use (to 3 atmospheres) means the watch is water resistant for occasional accidental splashing.
  • Page 36 Water resistance • Refer to the watch dial and the case back for the indication of the water resistance of your watch. The following chart provides examples of use for reference to ensure that your watch is used properly. (The unit “1bar” is roughly equal to 1 atmosphere.) •...

  • Page 38: Precautionary Items And Usage Limitations

    Precautionary items and usage limitations CAUTION To Avoid Injury • Be particularly careful when wearing your watch while holding a small child, to avoid injury. • Be particularly careful when engaged in strenuous exercise or work, to avoid injury to yourself and others.
  • Page 39 Precautionary items and usage limitations • Even if your watch has a high level of water resistance, please be careful of the following. • If your watch is immersed in sea water, rinse thoroughly with fresh water and wipe with a dry cloth.
  • Page 40 For band adjustment, we recommend you consult the retailer from where the watch was purchased or your nearest Authorized Citizen Service Center. Some repair shops may charge a nominal fee for adjustment if the watch was not purchased directly from them.

  • Page 41: Static Electricity

    Precautionary items and usage limitations <Magnetism> • Analog quartz watches are powered by a step motor that uses a magnet. Subjecting the watch to strong magnetism from the outside can cause the motor to operate improperly and prevent the watch from keeping time accurately.
  • Page 42 Precautionary items and usage limitations <Protective Stickers> • Be sure to remove any protective stickers that may be on your watch (case back, band, clasp, etc.). Otherwise, perspiration or moisture may enter the gaps between the protective stickers and the parts, which may result in a skin rash and/or corrosion of the metal parts.

  • Page 43: Caring For Your Watch

    Precautionary items and usage limitations Caring for Your Watch • Wipe any dirt or moisture such as perspiration from the case and crystal with a soft cloth. • For a metallic, plastic or rubber (urethane) watchband, wash any dirt off with water. Remove the small amounts of dirt trapped between the crevices of the metallic band with a soft brush.
