## Description

A reliable digital watch for the casual sportster CasioWith the launch of its first watch in November 1974, Casio entered the wristwatch market at a time when the watch industry had just discovered digital technology. As a company with cutting-edge electronic technology developed for pocket calculators, Casio entered this field confident that it could develop timepieces that would lead the market.Today, Casio is focusing its efforts on solar-powered radio-controlled watches: the built-in solar battery eliminates the nuisance of replacing batteries, atomic timekeeping means the users never have to reset the time. Recently, Casio launched a series of Bluetooth watches that sync to the users cell phone to automatically update the time. Casio is always moving time forward.

Review: A Timeless Classic Every Collector Should Own - Just received my Casio F91W-1 and I absolutely love it. Lightweight, super comfortable, and packed with useful features like alarm, stopwatch, backlight, and calendar. The battery lasts up to 7 years (according to the watch tag) and the timekeeping is incredibly accurate. It may be simple, but that’s the charm. It’s iconic, reliable, and extremely affordable, every watch collector should have one in their collection. A true classic that never goes out of style. Highly recommended!
Review: Solid watch - Several months ago,I picked up the Casio A158wa-1jf for just under $20 dollars, and was pleasantly surprised at the stylish yet functional watch I’d received. Unfortunately, I lost it, so after perusing desertcart I decided to go for the classic F91W-1. It’s hard to get excited about a $15 dollar watch, but this watch delivers in too many ways not to get excited about it. First and foremost, it keeps good time and is easy to read. The watch is easy and intuitive to set (I just glanced at the manual), and the functions that it comes equipped with do their job well. My only complaint would be that the strap could use a little extra length. I have an 8 inch wrist, so a little extra real estate would be nice. The lume function also isn’t phenomenal, but it does the job on a dark night. In terms of water resistance (something that was fairly important to me) this watch appears impervious to any normal person’s needs. Washing hands, showering, or getting caught in rain pose no issue to the watch. I’ve also jumped off of a 33 foot bridge while wearing this watch, which would expose it to all kinds of pressures and stresses it’s not designed to take. The watch was fine. No fog under the dial or any apparent damage. If you’re looking for a watch that is under $20, does its job well, and packs respectable water resistance, id recommend this watch.

## Questions & Answers

**Q: Does this watch have a backlight?**
A: Yes, but it is dim and primarily lights up the left side of the watch. It can be difficult to read while lit and must be pressed down to keep lit. Also, the button for the backlight has several other functions, and so you cannot keep the watch lit while performing those other functions.

**Q: Can it be set for military time?**
A: Yes

**Q: How is the backlight?**
A: The backlight is fine.  In my opinion, this watch is the best watch on the market, except for it's band which breaks too soon.

**Q: is it authentic or replicate? How is your package?**
A: hi 
thank you for your interest in our watch 
THIS WATCH IS AUTHENTIC  NEW IN THE ORIGINAL BOX 
thank you for your trust

### ⭐⭐⭐⭐⭐ Great watch
*by G***Y on February 1, 2024*

This is a great watch just like I had years ago. I haven't been wearing a watch for a long time but get tired of digging my phone out of my pocket or purse, especially when I'm out walking or shopping. I'm setting it up now and then going for a walk. The instructions are in extremely fine print and multiple languages. I scanned the English into my computer and enlarged it, saved as a PDF file and put on my phone in case I need to refer to them when I'm out and about. You may need a magnifying glass if you don't have that capability. I ordered it last evening and it came today already! Great job, Amazon! UPDATE: The alarm works well because it beeps and keeps beeping until you turn it off. However, the hourly chime is not so great. The chime is not as loud as the alarm and only goes "beep-beep" once. So if I'm not paying attention, the watch is under a sweater sleeve, or there's other background noise, I miss it. The whole purpose for me was to have an audible reminder every hour so I would get up and walk around, but I miss it more than I catch it.
