Gear Review | Casio F-91W | Outdoor Instructor

The 'Classic Casio' is used by most of our instructors.

We've always paid full price for our Casio Watches, we've never even had a discount (we don't really need one when they cost less than £10).

No other piece of equipment is so universally used within Land & Wave. 

Our staff use a real variety of clothing and equipment but almost everyone has a Casio F91 attached to their wrist or buoyancy aid.

We love these tough, inexpensive, functional little watches.

Why do we use them?

We can't remember when we all started wearing Casio Classic watches at work.

We can't remember a time when we didn't all wear Casio Classic watches at work.

Sam has had her Casio Classic for 7 years, since she first started Outdoor Instructor Training with Land & Wave. In that time, her watch has (at least) been coasteering 600 times, kayaking  300 times, rock climbing 250 times, days in the woods, days stomping up mountains and paddling down rivers.

Her watch has been submerged (most of the time), smashed into rocks and dropped into sand and is still going strong.

Sam's watch cost £7. The picture below is Sam's Watch, it's a bit battered, a little scratched but still going strong after 7 years of abuse.

What Casio Say...

A tried and true style great for casual wear. With its daily alarm, hourly time signal and auto calendar, you’ll never need to worry about missing an appointment again. Casual Classic watch with a Resin Band.

The Casio F91W is a quartz digital watch that was introduced in 1989, it's still in production and demand, 30 years later.

Key Features (so they say)

  • Includes alarm, stop watch and back light
  • Shatter-resistant acrylic window lens
  • Square high-performance and durable resin case with digital display
  • Durable and strong resin 15mm wide bracelet with buckle
  • Reliable quartz crystal movement technology for precise and accurate time keeping

Technical Specification...

The watch has a reliable rubber seal between its steel back and case but does not have any seals for its buttons, they fit tightly but at a certain point any pressure will avail, hence the watch is marked 'water resistant'. The watch case measures 37.5 × 33.5 × 8.5 mm and weighs 21 g.

What we've found - The F91W can be submerged, very often, with no ill effects

The watch is powered by a single CR2016 3-volt lithium button cell, which will last at least seven years, assuming 20 seconds of alarm and one second of light usage per day, however it is not uncommon that the battery would last even longer.

What we've found - The oldest Casio (we think) at Land & Wave is 11 years old and going strong.

5 Awesome Casio Facts...

  1. Holding down the right button for 5 seconds displays ‘CASIo'
  2. If you press all the buttons at once, all the digits display simultaneously
  3. Guantánamo Bay analysts say that wearing a Casio F91 is evidence of being in al-Qaida (really!)
  4. The lowest possible time to get if you 'double tap' the stopwatch is 00:00 15. The lowest we can get is 00:00 19
  5. Stopping the stop watch on exactly one second is physically impossible

Should you buy a Casio F91 if you work as an Outdoor Instructor 

Yes you should.

The Classic F91 costs very, very little money and will last you a long, long time.

Even if you smash your Casio into a rock one to many times and it dies an honourable death after many years of service it'll cost you less than £10 to replace it.

The Casio F91 is compact, robust and functional.

Land & Wave help people have incredible adventures in Dorset, the UK and Europe.

Every winter we run an Outdoor Instructor Training Course that we’re really proud of.
