TO PRESERVE THE QUALITY OF YOUR WATCH

Daily Care

The watch requires good daily care.

• Wipe away moisture, sweat or dirt with a soft cloth.
• After soaking the watch in seawater, be sure to wash the watch in clean pure water and wipe it dry carefully.
  • If your watch is rated as “Non-water resistant” or “water resistant for everyday life,” do not wash the watch. Do not pour running water directly from faucet onto the watch. Put some water into a bowl first, and them soak the watch in the water to wash it. → “Performance and Type” on P. 21 → “Water Resistance” on P. 22

Performance and Type

The case back shows the caliber No. and performance of your watch.

Water Resistance

Refer to the table below for the water resistant performance of your watch before use. (Refer to P. 21.)

Indication on the Case Back| Water Resistant Performance| Condition of Use
---|---|---
No indication| Non-water resistance| Avoid drops of water or sweat
WATER RESISTANT| Water resistance for everyday life| The watch withstands accidental contact with water in everyday life.| WARNING Not suitable for swimming
WATER RESISTANT

5 BAR

| Water resistance for everyday life at 5 barometric pressures| The watch is suitable for sports such as swimming.
WATER RESISTANT

10 (20) BAR

| Water resistance for everyday life at 10 (20) barometric pressures| The watch is suitable for diving not using an air cylinder.

Band

The band touches the skin directly and becomes dirty with sweat or dust. Therefore, lack of care may accelerate deterioration of the band or cause skin irritation or stain on the sleeve edge. The watch requires a lot of attention for longer use.

Metallic band

• Moisture, sweat or soil will cause rust even on a stainless steel band if they are left for a long time.
• Lack of care may cause a yellowish or gold stain on the lower sleeve edge of shirts.
• Wipe off moisture, sweat or soil with a soft cloth as soon as possible.
•  To clean the soil around the joint gaps of the band, wipe it out in water and then brush it off with a soft toothbrush. （Protect the watch body from water splashes by wrapping it up in plastic wrap etc.）
• Because some titan bracelets use pins made of stainless steel, which has outstanding strength, rust may form in the stainless steel parts.
• If rust advances, pins may poke out or drop out, and the watch case may fall off the bracelet, or the clasp may not open.
• If a pin is poking out, personal injury may result. In such a case, refrain from using the watch and request repair.

Leather band

•  A leather band is susceptible to discoloration and deterioration from moisture, sweat and direct sunlight.
• Wipe off moisture and sweat as soon as possible by gently blotting them up with a dry cloth.
• Do not expose the watch to direct sunlight for a long time.
• Please take care when wearing a watch with light-colored band, as dirt is likely to show up.
• Refrain from wearing a leather band watch other than Aqua Free bands while bathing, swimming, and when working with water even if the watch itself is water-resistant enforced for daily use （10- or 20- BAR water resistant)

Silicone band

• As for material characteristics, the band is easily dirtied, and may be stained and discolored. Wipe off dirt with a wet cloth or cleaning tissue.
• Unlike bands of other materials, cracks may result in the band being cut. Take care not to damage the band with an edged tool.

Polyurethane band

• A polyurethane band is susceptible to discoloration from light, and may be deteriorated by solvent or atmospheric humidity.
• Especially a translucent, white, or pale colored band easily adsorb other colors, resulting in color smears or discoloration.
• Wash out dirt in water and clean it off with a dry cloth. （Protect the watch body from water splashes by wrapping it up in plastic wrap etc.）
• When the band becomes less flexible, have the band replaced with a new one. If you continue to use the band as it is, the band may develop cracks or become brittle over time.

Remarks on Battery

Notes on the battery

1. Battery life
   This watch keeps operating for approximately 4 years if a new normal battery is inserted in it.

   • If the time synchronization via the Bluetooth communication is used more than once a day, however, the watch may run down in less than 4 years.

2. Monitor battery
   The battery in your watch is a monitor battery which is inserted at the factory to check the function and performance of the watch. Its actual life once in your possession may be less than the specified period.

3. Battery replacement

   • For battery replacement, be sure to have the battery replaced with a new one at the retailer from whom the watch was purchased, specifying a genuine SEIKO battery.

   • If the old battery is left in the watch for a long time, a malfunction may be caused due to battery leakage, etc. Have it replaced with a new one as soon as possible.

   • Battery replacement is made at cost even if it runs down within the guarantee period.

   • Once the case back is opened for battery replacement or other purposes, the original water resistant quality designed for the watch may deteriorate when it is closed. When you have the battery
     replaced with a new one, also request the water resistance test  suitable for the water resistant quality of your watch. If your watch has 10-bar or higher water resistant quality, be sure to have such test performed on the watch every time the battery is replaced. Please note that it takes several days to check the water resistant quality of your watch. When requesting the checking, therefore, please confirm the period required for it.

   • If the watch stops operating soon after the battery is replaced with a new one, it needs to be overhauled. (Refer to P. 25.)
