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 ### ⭐⭐⭐⭐⭐ It is what i like to gift *by on Reviewed in the United Arab Emirates 17 May 2026* Original good color ### ⭐⭐⭐⭐⭐ Bon materiel *by on Reviewed in Belgium 13 January 2026* Magnifique ### ⭐⭐⭐⭐⭐ Calidad de un Casio *by on Reviewed in Mexico 16 June 2026* Esta precioso me encanto 😍 lo comprare en más colores sin duda ## Frequently Bought Together - Casio F91W Series | Digital Watch | Water Resistant | LED Light | 1/100 SEC Stopwatch | Regular Time Keeping (HR, Min, SEC, PM, Date, Day) | Daily Alarm | Lightweight | 7 Year Battery - Casio AE1200WH Series | Men’s Digital Watch | 100M WR | Multi Alarms | 100 SEC Stopwatch | Countdown Timer | World Map for World Time | LED Light | LC Analog Display | 10 Year Battery - Casio A158WA Series | Unisex Digital Watch | Vintage | WR | 100 SEC Stop Watch | Daily Alarm | Regular Time Keeping: Hour, Minute, Second, PM, Date, Day | Led Light | 7 Yr Battery --- ## 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/255894349-f91w-series-digital-watch-water-resistant-led-light-1-100](https://www.desertcart.tn/products/255894349-f91w-series-digital-watch-water-resistant-led-light-1-100) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-09*
