Seiko Watches: Care & Maintenance

How does magnetism affect quartz watches?

It doesn't usually affect digital quartz watches, but it can affect analogue watches, which use a tiny electric motor to turn the hands. Powerful magnetism can affect the performance of this motor.

The good news is that although analogue watches may gain time, lose time, or even stop under the influence of powerful magnetic fields, they will usually return to normal time-keeping as soon as they leave the source of magnetism. (You may need to reset your watch, of course.)

Avoid putting your watch near medical equipment, headphones, loudspeakers, or refrigerator door magnets. Electric mixers and blenders and a wide range of other electrical equipment may also have strong enough magnetism to affect timekeeping.

What special care should I give my watch?

Shocks: Your watch is a precision measuring instrument. Treat it carefully, and it will serve you well. Avoid undue shocks (such as dropping on hard surfaces). The normal shocks caused by sports like tennis or golf present no threat, but "Twin Seiko" (extra-high precision) watches should not be worn while participating in such sports.

Perspiration: You should aim to protect your watch from heavy perspiration. Please remember to wipe it dry as soon as conveniently possible.

Temperature Extremes: Quartz watches are much less affected by extremes of temperature than mechanical watches, and are designed to keep good time if worn on the wrist for eight hours a day with ambient temperatures between -10°C and +35°C. If removed completely from the wrist, your watch may lose time during the winter, but will return to normal accuracy as soon as you start wearing it again.

If your watch is stored at temperatures outside the normal range (as low as -10°C or as high as +60°C) the electronic components may cease to function normally.

The response time of liquid crystals used in the displays on digital watches at temperatures below freezing is slow, and they tend to look very dark at high temperatures, but normal performance returns at normal temperatures.

Battery life can be significantly reduced at high temperatures (above 40°C), and battery fluid may even leak out.

Chemicals: Chemical substances, gases, mercury, etc., may change the color of cases, bracelets and straps. Mercury (for instance, from a broken thermometer) can cause particularly unsightly grey discoloration of gold plating.

How should I care for my watch case and bracelet?

Metal bracelets should be washed carefully in water. If really dirty, use a soft toothbrush with soap and water to brush away the dirt. Finally, rinse with water and dry carefully with a soft cloth. If your watch is not water resistant, be careful not to get water on the case. Cases should be wiped gently with a slightly moistened soft cloth and then dried carefully.

Leather straps should be slightly loosened in the summer, when they may absorb perspiration. A tight strap not only prevents the passage of air over the strap undersurface but can also cause a perspiration rash on the wrist.

If the strap ever becomes wet with perspiration, wipe it dry with a soft cloth.

When you take off your watch, leave it in a well-ventilated spot. Never put it in a sealed container when it is still damp with perspiration.

Avoid leaving your watch in direct sunlight. The strap color may fade.

Why does Seiko recommend servicing your watch about every three years?

Seiko watches are designed to provide accurate and reliable service over a long period. However, like any sensitive precision instrument, a watch needs periodic servicing to ensure that it functions perfectly. Frequency of such work depends on the climate and the owner’s individual care of the watch, but in general, we recommend having your watch serviced about every three years at an Authorized Seiko Service Center.

 

Worn out movement parts and aged oil inside the movement may cause a watch to lose time or stop. Therefore, our technical specialists will inspect the watch for any worn out parts that need repair or replacement, and the disassembled parts will be cleaned and oiled again. Furthermore, a watch’s water resistance is not permanently guaranteed. It is affected by the ageing of gaskets or deformation of watch parts due to an accidental shock. Since deterioration of gaskets can cause rust or moisture inside the movement, we recommend that you have the water resistance of the watch checked regularly to ensure it’s functionality.

What can I do when I experience an allergic reaction to a watch?

As with eye-glass frames or accessories, skin irritation may result from metal ions from the metal parts of a watch being extracted by perspiration. This kind of reaction is categorized as allergic skin dermatitis, which is caused by metals such as nickel, cobalt or chrome. These metals are included not only in metal bands but also in leather straps (chrome is used for tanning).

If you experience allergic reaction, stop wearing the watch immediately and consult a dermatologist. With a doctor’s assistance, clarify which metal caused the allergic reaction, and try to avoid selecting products which contain this metal. For those who are allergic to nickel or hyper-sensitive to stainless steel, we recommend that you use a titanium watch. For information on Seiko products made of titanium, please contact an Authorized Seiko Service Center.
