I was looking for an alternative for Casio F-91W and this model came up.
Good thing I chose this too, because larger models will appear comical on my wrist.
Ohhhhhhhh! I was really confused for a sec when I saw "EL BACKLIGHT" on one of the buttons. I thought it was just a really crummy translation into Spanish.
I would be in heaven if Casio would make this exact watch but with the ability to do a vibration and show a little bell icon on the display when you get a notification on your phone. No fancy pants smart watch functions just a regular old Casio that can alert you when you get a notification. I know this isn't really possible because adding Bluetooth would decimate the battery, but I'm so disillusioned with all the smart watches that have full color displays and a million features I never use when all I really want is to tell time and be alerted to notifications without hearing a sound.
Have you checked out the Xiao Mi Smart Bands? They come with the fitness thing and for notifications to work you gotta have the app and pair it to your phone (obv.) but you can disable mostly everything and the battery holds for like 2 weeks or so.
I use mine pretty much only to get wrist vibration and also for music control
Casio has a store locator online! & obv you can purchase online from many different sites! For Japanese only models, you can find reputable seller websites, like Sakura watches, or eBay.
