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. ## Features - Micro Light, Hourly Time Signal, Auto Calendar - 12/24 Hour Formats - Dial Code: Digital - Water Resistant - Daily Alarm ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00006I551 | | Additional Features | Alarm | | Age Range Description | Adult | | Band Color | Black | | Band Material Type | Resin | | Band Width | 20 Millimeters | | Bands | 1 | | Best Sellers Rank | #739,942 in Clothing, Shoes & Jewelry ( See Top 100 in Clothing, Shoes & Jewelry ) #2,139 in Women's Wrist Watches #3,618 in Men's Wrist Watches | | Brand Name | Casio | | Case Diameter | 38.2 Millimeters | | Case Material Type | Resin | | Case Thickness | 8.5 Millimeters | | Clasp Type | Buckle | | Closure Type | Buckle | | Crystal | Crystal | | Customer Reviews | 4.6 out of 5 stars 7,173 Reviews | | Dial Color | Black | | Display | Digital | | Embellishment Feature | Crystal | | Face Style | Black | | Item Weight | 0.19 Pounds | | Manufacturer | Casio | | Manufacturer Part Number | F-91W-1 | | Manufacturer Warranty Description | 1 year warranty | | Model Name | F-91W-1 | | Model Number | F-91W-1DG | | Pattern | Solid | | Power Source | Battery Powered | | Series Number | 178 | | Shape | Rectangular | | Sport Type | Walking | | Strap Type | Two Piece Strap | | Style Name | Chronograph,Digital | | Theme | Sports | | UPC | 079767299248 079767246280 | | Warranty Type | Casio 1 year warranty | | Watch Movement Type | Quartz | | Water Resistance Depth | 200 Meters | | Water Resistance Level | Water Resistant | ## Images ![F91W-1 Casual Sport Watch - Image 1](https://m.media-amazon.com/images/I/61ywHRkBhyL.jpg) ## 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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ A Timeless Classic Every Collector Should Own *by A***S on July 22, 2025* Just received my Casio F91W-1 and I absolutely love it.

Unless you really like banging your watch into the frame of every doorway you walk through. *by S***R on May 13, 2016* Anything I could say about this watch has already been said here. This is the number one selling watch in the world. Total production of the F91W since 1991 certainly adds up to more than all of the other digital watches made in the world... combined. If you eliminated one or two of the runners-up, there have probably been more F91Ws produced than all other wristwatches in the history of the planet added together. You don't achieve this sort of ubiquity by producing anything short of a design masterpiece. Yes, it's small. If you like to go around looking like you've got a cat food can duct-taped to your wrist, you will not like this watch. During the first Gulf War, I was so impressed at how enormous the 5600 G-Shocks that the Navy SEALs on board my ship were wearing in comparison to my dinky little F91W. The main complaint about the 5600 Series G-Shocks today is that they are too small. Go figure. Yes, the strap is short. I've got a pretty average-sized wrist and I'm buckling on the last couple of holes. There are remedies to this problem but a new band will probably double the cost of wearing this watch. If you've got Popeye forearms, you may want to look elsewhere. Other than that, I can't think of anything less than glowing to say about this watch. I've owned several over the years and, while I've followed the trends and have a few cat food cans myself, my newest F91W is getting a lot of wrist time recently. There is a lot to be said for a rugged little watch that costs less than $10, doesn't interfere with the cuff of your shirt, weighs almost nothing and doesn't make it impossible to fasten the velcro closure on my work gloves. ## Frequently Bought Together - CASIO F91W-1 Casual Sport Watch - Casio F91WG-9 Men's Retro Black Band Gold Face Alarm Chronograph Digital Watch - Casio Men's Vintage F105W-1A Illuminator Water Resistant Sport Watch --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/811181-f91w-1-casual-sport-watch](https://www.desertcart.co.th/products/811181-f91w-1-casual-sport-watch) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-06-11*
