Maintenance
Battery Replacement
The Casio DW-291HX-5AV is equipped with a 10-year battery. When the watch display becomes dim or functions become erratic, the battery may require replacement. It is highly recommended to have the battery replaced by a qualified watch technician to ensure the watch's water resistance and proper functionality are maintained.
Water Resistance (200M)
This watch is rated for 200 meters of water resistance, making it suitable for swimming, showering, and snorkeling. To prevent damage, do not operate any buttons while the watch is submerged in water. Avoid exposing the watch to hot water or steam, as high temperatures can compromise the integrity of the watch's seals.
