Усны хамгаалалт (100М)

This watch is rated for 100-meter (330 feet) water resistance. This means it is suitable for swimming, showering, and recreational water activities. It is not suitable for scuba diving or high-impact water sports.

Засвар үйлчилгээ

Цэвэрлэгээ

  • Wipe the watch case and band with a soft, dry cloth regularly to remove dirt and moisture.
  • For resin bands, a mild soap solution and a soft brush can be used, followed by thorough rinsing and drying.
  • Химийн цэвэрлэгч, уусгагч эсвэл зүлгүүрийн материал хэрэглэхээс зайлсхий, учир нь эдгээр нь цагны өнгөлгөөг гэмтээж болзошгүй.

Зай солих

The watch is powered by one SR920SW battery, which has an approximate lifespan of 3 years. When the watch stops or the second hand moves erratically, it indicates a low battery. Battery replacement should be performed by a qualified watch technician to ensure proper sealing and water resistance.

Усны эсэргүүцэлтэй холбоотой урьдчилан сэргийлэх арга хэмжээ

  • Have the water resistance gaskets checked and replaced every 2-3 years, especially if the watch is frequently exposed to water.
  • Avoid exposing the watch to extreme temperature changes, which can affect the water resistance seals.

Алдааг олж засварлах

  • Цаг ажиллахгүй байна: Титэм бүрэн шахагдсан эсэхийг шалгана уу. Хэрэв байгаа бол батерейг солих шаардлагатай.
  • Цаг хугацаа буруу байна: Ensure the crown is fully pushed in. If the time continues to be inaccurate, the watch may require servicing.
  • Date does not change: Manually advance the date to ensure it is not stuck. If the issue persists, consult a service center.
  • Fogging inside the crystal: This may indicate a loss of water resistance. Avoid further water exposure and have the watch inspected by a technician immediately.
