Please carefully read the following maintenance guide about your watches.
Avoid strong impact, such as dropping it on a hard surface, because the watch is a precision instrument.
When pulling out the crown, do not put the watch in water.
Do not turn or pull out the crown when the watch is wet.
Even if the watch is waterproof, do not rinse it directly under the tap of tap water. The water pressure from the faucet is sufficient to cause the water to penetrate inside the watch.
The waterproof performance of the watch cannot be guaranteed forever. It will be affected by the deterioration of the gasket or the deformation of the watch parts due to accidental impact. We recommend that you regularly check the water resistance of your watch to ensure its functionality.
In order to maintain its waterproof performance as much as possible, after removing it from your wrist, wipe off moisture, sweat or dirt with a soft dry cloth.
Swim in the sea:
Wear a waterproof watch in sea water, wash it with clean water and dry it with a soft cloth after landing.
When pulling out the crown, do not wash the waterproof watch.
Avoid washing directly under running water. Please wash the watch in still water in a sink or container.
Bathroom or sauna:
Do not wear a watch when taking a bath or sauna. Certain ingredients in steam, soap or hot springs may accelerate the deterioration of waterproof performance.
The function of the watch is affected by extreme temperatures and extreme temperature changes.
Since the operating temperature range of each movement is different, please refer to the instructions for use of the watch movement.
Do not use solvents or chemicals (such as petroleum ether, thinner, bleach) to clean the watch. This may cause a chemical reaction and cause the watch to deteriorate or change the color of the case, strap, or strap.
Turn the crown from time to time to prevent corrosion of the crown and maintain the flexibility of the gasket.
For screw-in crowns, please tighten the crown carefully to prevent the penetration of moisture in the movement.
After removing it from your wrist, wipe off moisture, sweat or dirt with a soft cloth to improve the durability of the case back, gasket and strap.
How should I care for my watch strap?
Since the strap is in direct contact with the skin, it may be damaged or soiled by sweat or dust. Lack of maintenance may accelerate belt degradation, cause skin irritation or contaminate the edges of sleeves. Please follow the precautions below to keep the strap in its best condition for as long as possible:
Even stainless steel straps/straps rust due to corrosion/rusts/sweat accumulated in the middle of the straps. This is particularly prone to expensive solid straps, as the relatively narrow gaps between the links can easily accumulate rust/sweat. When you sweat, rust may cause yellow discoloration on the cuffs.
To prevent rust, please wipe off moisture, sweat or dirt with a soft cloth when convenient. To rinse the strap, when the surface stains are obvious, apply a neutral detergent (mixed with some water) on the metal strap/bracelet. For serious stains, please use a toothbrush to remove the stains accumulated in the gap between the strap/bangle link. Use plastic wrap, etc. to wrap the watch head to prevent moisture from entering the watch head. After cleaning, please use a towel to wipe the gap between the strap/bangle link carefully and dry the entire watch thoroughly.
*Some titanium watchbands use stainless steel needles, which are more durable than titanium. Therefore, even if your watch band is made of titanium, rust will form in stainless steel parts. If the corrosion spreads, the nails may protrude or fall off, the case may fall off the strap, or the buckle may not be able to be opened. If the pin protrudes, it may hurt the user. If this happens, do not use the watch and contact a Seiko authorized service center for repair.
Compared with metal straps/bracelets, leather straps are more susceptible to discoloration and deterioration due to moisture, sweat and direct sunlight. The leather strap may tear or the strap color may fade. Frequent maintenance is required, which includes the case of wearing a watch. Even if the watch itself is waterproof, do not wear a watch with a leather strap when bathing, swimming, and working with water. In addition, pay special attention when wearing a light-colored strap watch, because stains will be more obvious.
Wipe gently with a soft dry cloth to wipe off moisture and sweat as soon as possible, then remove it from your wrist and place it in a well-ventilated area. Do not expose the watch to the sun for a long time (such as on the dashboard of a car), as this may cause discoloration/deformation/breakage of the leather strap of the watch.
*Some straps are made of synthetic leather on the back (or even the entire strap), which is more resistant to sweat than leather straps. However, in any case, it is important to keep an eye on the strap.
The urethane strap is susceptible to discoloration by light, and may deteriorate due to contact with solvents or moisture in the atmosphere. If the strap is kept damp and in a location with high humidity or exposed to the sun for a long time, the deterioration rate may be accelerated and some cracks may appear on the surface of the strap. In addition, translucent, white or light-colored straps tend to absorb other colors, causing color stains or discoloration. Special attention should be paid to the condition of the urethane strap, which is usually worn for marine sports or outdoor activities.
Use water to wash off any dirt, and then wipe it thoroughly with a dry cloth (wrap the meter with plastic wrap to prevent it from getting wet).
*When the strap loses its elasticity, please contact Seiko Authorized Service Center to replace it with a new strap. If you continue to use the strap, it may crack or brittle over time.
What should I do when I have an allergic reaction to the watch?
Like eyeglass frames or accessories, skin irritation may be caused by sweat extracting metal ions from the metal part of the watch. This reaction is classified as allergic dermatitis caused by metals such as nickel, cobalt or chromium. These metals are not only contained in the metal watchband, but also in the belt (chrome is used in the tanning process).
If you experience an allergic reaction, stop wearing your watch immediately and consult a dermatologist. With the assistance of a doctor, clarify which metal causes allergic reactions, and try to avoid choosing products containing that metal. For those who are allergic to nickel or to stainless steel, we recommend that you use a titanium watch. For information about Seiko titanium products, please contact Seiko Authorized Service Center.
How does magnetism affect the watch?
The watch may be adversely affected by magnetism, so it may increase or lose time. It is important not to keep the watch close to magnetic objects for a long time, especially mobile phones, TV and PC speakers, magnetic necklaces, handbag buckles, hair dryers, electric razors, magnetic parts of refrigerators, etc. are all magnetic objects. Since the affected watch is still magnetized even after the magnetic source is removed, please contact the nearest Seiko authorized service center and we will demagnetize your watch.
Analog quartz watch:
Analog quartz watches use magnetic power to drive a stepping motor to move the rotating wheel. These stepping motors are very tiny and are easily affected by magnetic forces, which may affect the runner. Therefore, the watch may stop or fail to maintain the correct time.
Spring Drive watch:
Magnetism affects the internal parts of the movement, which may result in the inability to maintain the correct time.
A mechanical watch that is affected by magnetism remains magnetic even after being removed from the magnetic source. This may result in increased or lost time. The watch can maintain magnetic charging for a long time, so it is recommended that you perform demagnetization to improve accuracy.
Digital display quartz watch:
Generally speaking, the magnetic force has no effect because there is no motor in the digital quartz watch.
