Frequently Asked Questions
Can I swim and shower with it?
It is rated to 20 bar (200 metres), which suits splashes, rain, showers and swimming. It is not intended for scuba diving. Do not press the buttons when the watch is wet, and rinse it in fresh water after the sea or a pool.
Is it shock resistant?
Yes. It uses Casio’s shock-resistant construction, designed to withstand the knocks of everyday wear and active use.
What does hand shift do?
When the analog hands overlap the digital display, they move aside so the digital readout stays clear.
Does it have world time?
Yes. It covers 31 time zones (48 cities and UTC), with daylight saving time that can be switched on or off and one-touch access to UTC.
How long does the battery last?
Approximately 7 years on a CR2016 battery. When the battery runs out, have it replaced as soon as possible to prevent any malfunction.
