Casio F105W-1A Illuminator Watch

Product Information

Given [Rotislav’s] results, we’d be far more confident getting our affordable Casio watches a little wet. Obviously, we wouldn’t expect to make a warranty claim if damage occurred from use outside the specs, but it’s clear the watch is far more capable than standards might suggest. If that’s not enough though, you can always set about modifying the watch to improve its water resistance even further. Synthetic resin is the ideal material for wrist straps thanks to its extremely durable and flexible properties. The daily alarm reminds you of events that recur every day, by emitting an audible signal at the set time. While I described the W93H as a bit of a dud for me in my last article, the F105W is a total winner in my book. I don't know exactly when this watch was introduced to market, but it definitely came shortly after Timex released watches with the the Indiglo nightlight technology in 1992. My guess is that at earliest, the F105W is probably a design from the mid-1990s. Is the F105W exactly the same as the F-91W?

Because of this, it isn’t uncommon to see individual watches exceed their rated pressures, and also to fail well below their rated pressures, even in the same make and model for cheaper watches.. For those not in the know, the F105W is like the F-91W, but with one rather important improvement. The nightlight is a million times better. This is why ILLUMINATOR is so prominent on the watch face. 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.) But both of those models have an amber nightlight that while it does work very well, it's not the cool blue one.Water resistance is an important feature of a modern watch. It makes wearing the watch far more practical in this modern world of sudden rainstorms and urban water balloon ambushes. The Casio F91W, one of the company’s most popular watches, is claimed to be water resistant to “30 meters”, which in ISO parlance, means it is suitable for splashes and rain resistance only. [Rostislav Persion] wanted to get a better idea of what this really meant, so set about investigating for himself.

and neither Walmart nor Target carry it as far as I know. Personally, I had to buy mine online just to get one. Resin is made of synthetic resin and is the ideal material for bracelets due to its extreme durability and flexibility.

Elapsed time, split time and final time are measured with 1/100-sec accuracy. The watch can measure times of up to 1 hour. Elapsed time, split time and end time are measured with an accuracy of hundredths of a second. The measuring capacity of the watch lasts up to one hour.
