N'ah mate, I feel Casio is also quite cheeky with their pricing for what is essentially mass produced budget commodity 80's tech made in China from cheap plastics.
Here in Europe most of their basic watches (excluding the F91W) are over 40+ Euros and all they do is show time/date on a cheap LCD display with poor viewing angles in a plastic resin shell who's paint rubs off after a couple of years.
Meanwhile for that price you can get an Xiaomi smart band with OLED display, gorilla glass, Bluetooth, vibration, heart-rate sensor, and it even tells time. Casio's profits must be crazy good on those watches.
I wish they would sell more models in metal casings like in the 80's and with updated internals with more functionality.
