It always amazes me that Casio can provide so much bang for the buck in throughout their collection. The Watch Factory recommends purchasing a watch of at least 20ATM if you wish to wear your watch whilst swimming, bathing or showering. Wearing a watch with a lower ATM whilst swimming, bathing or showering may not always damage the watch, however we urge on the side of caution due to the delicate nature of watches. They should be in their original condition, unworn, unused, with all tags still attached, and in the original packaging.

So someone suggested trying to swap out the F91 module with the F105 since it has the proper backlit "Illuminator" and they're very similar. I recently got into the habit of wearing a watch again after a lapse of a few years (after using a fitbit for a month and deciding to throw it away . It fits under shirt cuffs easily, the buttons are easy to understand and operate, and the band isn't an overblown look-at-me size. They are a popular choice for people who want a reliable and functional watch without breaking the bank. In Walmart for example, you'll easily find the F-91W there as well as the F108 and the recently introduced W217 (very similar styling to the F-91W but larger with notably better nightlight.Functionality: Casio watches come with a range of useful features, such as stopwatches, countdown timers, alarms, and world time. Overall you'd be receiving relatively similar watch made almost entirely of resin while the back is still stainless steel yet again. I'm not saying you can't see it completely dark at night but it's a really poor light that I believe should stay in the 1980s.

Innovation: Casio has a reputation for innovation, and their watches often feature new technologies and features that set them apart from other brands. For example, if your watch has an ATM of 5, you can safely use it when you're washing hands and if it's raining outside, but you should not take it diving, swimming, bathing or showering. But both of those models have an amber nightlight that while it does work very well, it's not the cool blue one.

If there is weak spot it is the bands get old and break probably from the solvents mine are exposed to. This does not mean that a watch can be taken 10 metres below sea level - although that is a common misconception. As such, the F-91 is the quintessential digital watch and probably the last 'new' model with the standard LED light. Please note that if you have purchased a product via a marketplace such as Takealot you will need to deal directly with them with regards to product issues or queries.

Think of the F-91 as a day time watch and the F-105 as evening wear, when you're more likely to need the backlight. If by chance you haven't seen the F91W before that is completely fine, if you purchase the watch, you'd be receiving a smaller digital watch with resin construction. Casio is a renowned brand in the world of watches that has been producing timepieces for over 70 years. The F105 with the illuminator is indeed a night-and-day difference with the other aspects (dimensions, weight almost the same) I liked the feather-like weight of the F91W (about 20g) a LOT and was a primary reason to also go for the F105W.

I've had one of these watches for some years and wear it everywhere - office, working on cars, yard work, so on.In this post I will be preparing a run down/comparison of the F91W and F105W incase if your in the market for either or.
