Casio is doing something cool in August by launching a modern version of one of their classic vintage watches, but upgraded with Bluetooth and even a step tracker. So far it’s only on the shelves in Japan though: https://www.amazon.co.jp/CASIO-Collection-F-B100W-1AJF

So on the surface the Casio F-B100W-1AJF watch looks just like a vintage electronic watch from the 80’s. But upon closer inspection you see that it even has Bluetooth and step tracker written on it. The LCD screen has modern LED backlight too, instead of just a small lamp, so you can use it at night.

The launch price in Japan is 8800 Yen, which converts to about 55 US Dollars by todays exchange rate.
