Casio F105W-1A Illuminator Watch

Product Information

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.

The ATM of a watch is short for Atmospheres and is a measure of the level of water pressure a watch is designed to withhold. If you believe that there is any damage to your watch, it is best to get it assessed by a watch maker who can check the water resistance is intact. 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. 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.

Overall you'd be receiving relatively similar watch made almost entirely of resin while the back is still stainless steel yet again. Casio watches are recognized for their ruggedness, precision, and reliability, making them suitable for various activities such as sports, outdoor adventures, and daily wear. Also please note deliveries will only take place during business hours during the week between (8-30am and 5pm).

Illuminator watches like my W-800H and B640W both have even sharper digits and a diffuser layer that spreads the light more evenly - making the display fully readable in the dark. People for a long time lived with the reduced contrast because they liked the way that the illumination looked.The company is known for its innovative and functional watches that are popular among both casual users and professionals. I've had one of these watches for some years and wear it everywhere - office, working on cars, yard work, so on.

If there is weak spot it is the bands get old and break probably from the solvents mine are exposed to.

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. Now that so many people are born with 1000 nit TFTs, 18 hours a day of screen time, 4K displays, and are generally so obsessive-compulsive about everything, they are switching to LEDs.

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. Viewing angles of both are about the same with other segments of the display not showing up at a larger viewing angle of incidence. The F-91 appeared in 1990 and was very much a homage to similar watches of the 70's and 80's that pretty much all featured a virtually useless LED bulb. If you watch any episode of ELR you will see one button on the right side of the watch during closeups. I agree with the other reviewers that this is a top choice for a basic functioning, dependable, and efficiently programmed watch.A common issue is when the crown has come loose and the seal has been damaged, which allows moisture to get in. Anyway when it comes to the display crispness, and ease of reading in a slightly less lit environment, the F91W seems be very superior. For example, their G-Shock line of watches is known for its shock-resistant and water-resistant features, making them popular among outdoor enthusiasts and adventurers. It feels super comfortable in long periods of wear, to the point where I almost forget that it's on my wrist because of the slimness from the quartz movements you don't have to worry about banging into a wall as you walk by.
