Back in 1990 gas was $1.16/gal. The average home price was under $150000. As time moves on prices go up. **Q: Does the count down timer be set to seconds?** A: No countdown timer. Look at Model F201WA-1A for that feature. **Q: how far in depth is the water resist** A: If you want to be absolutely safe, get the Casio MRW200 dive watch which is good for 100 m. Casio F91W is water resistant and you could take it in shower, swimming, etc. **Q: The rubber band broke after 2 years of use. I love this watch and don't want to get a new one. Any tips for a replacement band? Maybe a nylone one?** A: Aliexpress or ebay you'll find almost exact generic replacements for a couple bucks shipped. Search for words like F91W strap, 18mm watch band. You can also use normal 18mm spring bars instead of the pins that are stock with the F91W. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Classic Watch and She Loves It! *by M***R on July 22, 2026* A classic, simple, and reliable watch. My wife loves it! Lightweight, comfortable, and easy to use with a timeless design. Great value for the price and a perfect everyday watch. ### ⭐⭐⭐⭐⭐ Great product great price *by A***N on July 15, 2026* Great color and style, the light is a little dim but it’s nice at night to check the time and not be blinded by your watch ### ⭐⭐⭐⭐⭐ Amazing Watch, except a few things. *by B***N on August 19, 2025* This watch is absolutely AMAZING! It looks very unique with its own design but still manages to look nice no matter the occasion. The features are nice, I like the stopwatch but the alarm personally isn't loud enough for me, but that doesn't matter because most people don't use their watch for alarms. I haven't worn it enough for durability yet but it with stands scratches pretty well. The band is also very comfortable and easy to adjust. It's the perfect watch if you just want a watch not nice enough to be a rolex, but not smart enough to be an apple watch. Just time! And time is does incredibly well, it's very reliable, looks nice, and I forget I'm even wearing it. Okay here are the not-so-good parts, (this watch is perfect but here's what the picky people should look out for) The few times I need to click the buttons they feel weirdly uncomfortable to press and hard. Also, the backlight is VERY dim, I know it's too small to but a full backlight but atleast more than one LED. I have to squint to see it and the oppisite side you can't see anything. Doesn't come in clutch the few times I need to use the light. ## Frequently Bought Together - Casio - Casio Classic F91W Series Quartz Watch | Water Resistant |1/100 Second Stopwatch | Daily Alarm | Hourly Time Signal |Auto Calendar |SS Caseback |12/24-Hour Format - CASIO STANDARD DIGITAL WATCH WITH LED-LIGHT F-91W-1JF --- ## 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.tn/products/39743796-f91w-series-digital-watch-water-resistant-led-light-1-100](https://www.desertcart.tn/products/39743796-f91w-series-digital-watch-water-resistant-led-light-1-100) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-24*
