How Long Do Casio F-91W Watches Last?

The lifespan of a Casio F-91W largely depends on how well it is taken care of and how often it is used. With proper care it can last for several years, if not decades.

One of the reasons why the Casio F-91W is known for its durability is its design. It is made with high-quality materials that are resistant to wear and tear. The watch’s resin case and band are tough and can withstand everyday use, while the mineral glass crystal is scratch-resistant.

Furthermore it’s also water-resistant, which helps to protect it from damage due to exposure to water or moisture. However, it is essential to note that the watch is only water-resistant up to 30 meters, which means it is not suitable for activities like swimming or diving.

In terms of battery life, the Casio F-91W uses a CR2016 battery, which can last up to seven years, depending on usage. It is essential to replace the battery when it runs out to avoid damage to the watch’s internal components.

How Many Casio F-91W Watches Are Sold Each Year?

How Do I Check If My Casio F-91W Is Original?

There are several ways to check if your Casio is original or not. Here are some of my tips:

Check the Packaging

An authentic Casio F-91W will come in a Casio-branded box with the watch’s model number and other information printed on it. The box should also have a holographic sticker that guarantees the watch’s authenticity.

Check the Watch Face

The watch face of an authentic Casio F-91W should have clear and crisp printing, with no spelling errors or smudging. The font should also be consistent throughout the watch, and the digital display should be evenly lit.

Check the Back of the Watch

The back of the watch should have the Casio logo and the watch’s model number engraved into it. The back plate should also be flat and flush with the watch case, with no visible gaps or seams.

Check the Functions

An authentic Casio F-91W should have all of its functions working correctly, including the timekeeping, alarm, timer, and stopwatch features. If any of these functions are not working or do not function correctly, the watch may be a fake.

Check the Price

While this is an affordable watch, if the price seems too good to be true, it may be a fake. Be wary of heavily discounted watches or sellers who are not authorized Casio dealers.

Overall, it is always best to purchase a Casio F-91W from a reputable dealer or directly from Casio to ensure that you are getting an authentic watch. If you are unsure about the authenticity of a watch, it is always best to have it checked by an authorized Casio dealer or watchmaker.
