การใช้งานนาฬิกาของคุณ
การเคลื่อนไหวอัตโนมัติ
Your Laco 861749 watch is powered by an automatic mechanical movement. This means it does not require a battery. The movement is wound by the natural motion of your wrist. When worn regularly, the watch will maintain its power reserve. If the watch is not worn for an extended period, it may stop. To restart it, gently shake the watch for a few seconds or manually wind it by turning the crown clockwise in its innermost position (before pulling it out for time setting) about 20-30 times. Then, set the time as described in the Setup section.
ความต้านทานต่อน้ำ
The Laco 861749 watch is water-resistant up to 5 ATM (50 meters or 165 feet). This rating means the watch is suitable for everyday use, including splashes, rain, and brief immersion in water. It is ไม่ suitable for swimming, showering, diving, or any water sports where the watch might be subjected to high-velocity water or prolonged immersion. Always ensure the crown is fully pushed in before any contact with water.
