  Otherwise, the pressure inside the watch will increase, and parts (crystal, crown, push button, etc.) may come off.

CAUTION When Wearing Your Watch

• Leather bands and rubber (urethane) bands will deteriorate over time due to perspiration or dirt. In addition, they are made of natural material and will be worn, deformed, and discolored over time. It is recommended to replace the band periodically.

• The durability of a leather band may be affected when wet (fading, peeling of adhesive), owing to the properties of the material. Moreover, wet leather may cause a rash.

• Do not stain a leather band with substances containing volatile materials, bleach, or alcohol (including cosmetics). Discoloration and premature aging may occur. Ultraviolet light such as direct sunlight may cause discoloration or deformation.

• It is recommended to take off the watch if it gets wet, even if the watch itself is water-resistant.

• Do not wear the band too tightly. Try to leave enough space between the band and your skin to allow adequate ventilation.

• The rubber (urethane) band may be stained by dyes or soil present in or on clothing or other accessories. Since these stains may not be removable, caution is required when wearing your watch with items that tend to easily transfer color (articles of clothing, purses, etc.). In addition, the band may be deteriorated by solvents or moisture in the air. Replace with a new one when it has lost elasticity or become cracked.

• Please request adjustment or repair of the band in the following cases:
  –You notice an abnormality with the band due to corrosion.

If paint thinner, benzene or other solvents or products containing these solvents (including gasoline, nail polish remover, cresol, bathroom cleaners and adhesives, water repellent, etc.) are allowed to come into contact with the watch, they may discolor, dissolve or crack the materials. Be careful when handling these chemicals. Contact with mercury such as that used in thermometers may also cause discoloration of the band and case.

< 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.

CAUTION Always Keep Your Watch Clean

• Rotate the crown while it is pressed in fully and press the buttons periodically so they do not become stuck due to accumulations of foreign matter.
• The case and the band of the watch come into direct contact with the skin. Corrosion of the metal or accumulated foreign matter may result in black residue coming from the bracelet when exposed to moisture or perspiration unnoticed soiling such as that caused by perspiration. Be sure to keep your watch clean at all times.
