First time in my life, I can remember my meds!!! - Finding watches for a small wrist is a struggle. This one is nearly perfect and I intend to wear it until it breaks. I had a couple resin Casio watches of a similar size in the past but the straps end up breaking. ADHD related pros: - I've yet to need to charge a battery on a Casio watch during its life. No charging! Smartwatches have more features, but they can be distracting and aren't useful for anything if they're dead. - I can set an alarm for my PM medication. Morning medication is easy to remember as I have it where I eat breakfast, but I never know what I'll be up to by the afternoon. - If I'm busy when that medication alarm goes off, I can just set the timer in a few button presses, without stopping what I'm doing and getting distracted. I can bump it 1-3-5-10-15-20-30 minutes. The bar underneath blinks when it is less than that time but more than the next shortest time. -If I'm going from one room to another for something, i.e. meds, putting dishes back in the kitchen, grabbing trash bags, getting a drink, plugging something in to charge... I can I set the 1-3-5 minute timer to remind me I was in the middle of something if (when) I get distracted midway. - Setting a timer for tasks where my time blindness can be a problem- showering, knowing when I need to leave the house for an appointment, when I need to get ready for someone coming over, how long I can spend in a store or go out for a walk.... I find I can often turn off the timer before it goes off as it makes me more conscious of time in general. - Silver color matches any & all outfits. Stays clean looking. - No frills. No extra distracting functions. Just what I need. Other pros: - Perfect face size. - I don't wear it in the shower regularly as I tend to chafe under watches if they get wet every day. However I have worn it multiple days hiking in nonstop rain, when swimming in the river, and showering away from home, and I never even thought to worry about it once. Overall cons: - No backlight (could be a plus if you're an insomniac and tend to watch the clock) - Latch seems fragile, but no real problems yet. - Need a tool to adjust wrist size - Very occasionally I hit the timer button on something and it goes off randomly. Overall I can absolutely reccomend this watch if you want something simple or have a poor working memory!! Review: Dainty, lightweight, practical! - UPDATE: Clasp broke after a few weeks of using. 🥹 Very lightweight and easy to adjust. I love having the alarm, timer, and stopwatch features. I have a petite wrist, and it’s perfect for starting the new school year. ## Features - RETRO-INSPIRED DESIGN WITH DIGITAL FUNCTIONALITY: The Casio LA-670WA-1 features a classic silver-tone stainless steel band with a compact resin and chrome-plated case blending vintage aesthetics with modern digital features.

Although a different style watch, this one helped me.... https://m.youtube.com/watch?v=_sKnDS8Uz90 or **Q: Is anyone concerned about or know anything about the birth defect warning on this watch?** A: You may be seeing a warning required by Proposition 65 in California that applies to numerous chemicals and substances. I generally don't pay much attention to it because it occurs so widely that I don't see how to avoid it. From wikipedia: "Proposition 65 is administered by Cal/EPA's California Office of Environmental Health Hazard Assessment (OEHHA).[2] Proposition 65 regulates substances officially listed by California as causing cancer or birth defects or other reproductive harm, in two ways. The first statutory requirement of Proposition 65 prohibits businesses from knowingly discharging listed substances into drinking water sources, or onto land where the substances can pass into drinking water sources. The second prohibits businesses from knowingly exposing individuals to listed substances without providing a clear and reasonable warning. " **Q: Do you have a same one with the same features (e.g. timer) for man? Thanks!** A: I believe there is a men's watch that is very similar ## Customer Reviews ### ⭐⭐⭐⭐⭐ Timer is an ADHD game changer!!

I love having the alarm, timer, and stopwatch features. I have a petite wrist, and it’s perfect for starting the new school year. ### ⭐⭐⭐⭐⭐ Great small watch! *by A***. on August 24, 2026* Great watch! If you’re looking for a high-quality small watch, please get this! It’s the perfect size for women with small wrists. It looks good with almost any outfit. I also love the fact that I don’t have to take out my phone to check the date/time. One tiny, very insignificant drawback is that the interface does not glow in the dark—but I'd still take this over any watch. ## Frequently Bought Together - Casio LF20W G-Shock Series | Unisex Digital Watch | Black | WR | 1/100 SEC Stopwatch | World Time | LED Light | Full Auto Calendar | Regular Time Keeping (HR, Min, SEC, PM, Date, Day) | 3 Year Battery - Casio W218H Series | Men’s Digital Watch | 50M WR | 1/100 Second Stopwatch | 100 SEC Chronograph | LED Backlight | Countdown Timer | Daily Alarm | Hourly Time Signal | 7 Year Battery - Casio MDV106 Series | Unisex Analog Watch | 200M WR | Stainless Steel Case | Resin Band | 2 Hand Analog (HR, Min, SEC) | Date Display | Screw Down Crown/Screw Down Caseback | 3 Year 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.jp/products/1723810-lf20w-g-shock-series-unisex-digital-watch-black-wr-1](https://www.desertcart.jp/products/1723810-lf20w-g-shock-series-unisex-digital-watch-black-wr-1) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-18*
