This is a Casio "Cheapo Casio" wristwatch. It arrived today, but it didn't feel right when I tried it on, so I'm putting it up for sale. I've only worn it once, so it's practically new. It comes with the box and instruction manual. The CASIO F-91W is a waterproof digital watch with alarm and stopwatch functions. - Brand: CASIO - Model Name: F-91W - Functions: Alarm, Stopwatch, Date display - Water Resistance: WR (Water Resistant) Thank you for looking.
