help Casio F-91W FAQ

What functions does the Casio F-91W actually include?

The F-91W includes a digital time display, daily alarm, hourly signal, stopwatch, calendar, and small LED light. Its controls are operated through three side buttons rather than a crown or touchscreen.

Can you swim while wearing a Casio F-91W?

Casio labels the F-91W water resistant, but it is not presented as a serious diving watch with a high depth rating. Owners commonly treat it as suitable for splashes and everyday exposure rather than deliberate swimming or underwater button use.

How long does the Casio F-91W battery last?

Casio specifies roughly seven years of battery life under its standard usage assumptions. The watch uses a replaceable CR2016 battery, although real endurance varies with alarm and light use.

How can I avoid buying a counterfeit F-91W?

Check the printing, case-back engraving, module behavior, and seller rather than relying on one supposed secret button test. Because the genuine F-91W is inexpensive and produced in very large numbers, counterfeits can imitate familiar markings surprisingly closely.
