Lost the manual and can't find it online! Thank you!** A: http://ftp.casio.co.jp/pub/world_manual/wat/en/qw2575.pdf Hello, this is the manual. Alarm always turns to default 12:00 **Q: Is the band one piece? Does it slip through behind the watch back? Skin sensitivity to metal contact.** A: The back of the watch is stainless steel and it will be touching your skin once on your wrist. **Q: Ok...this might be a silly question. I know it says running watch. My question is will it count steps while I walk?** A: No... It lets you time laps, or miles, or times between two points. Step counters are just "estimaters" usually not accurate. So, say you measure out a mile and you run that in 10 minutes. If you measure your running stride (say for example 8 strides in 20 feet running at your normal pace) that would be 30 inches. With 15,360 inches in a mile you would have 512 "steps" or "paces." You also will have to correct for walking, shorter strides, and step counters treat all steps the same even if you move 10 inches, shorter than a walking stride. **Q: Is there an option to remove the year from the display? Or to add a P or A (for pm or am)?** A: Yes, you can remove the date, however you cannot add 'am' or 'pm'. You do have an option to set it to military time, though. ## Frequently Bought Together - Casio Watch with Movement Japanese Quartz Movement Woman STR-300 – 1C 48.0 mm. - 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.pt/products/831402-str300-series-classic-dive-style-50m-wr-1-100-sec](https://www.desertcart.pt/products/831402-str300-series-classic-dive-style-50m-wr-1-100-sec) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-10*
