Most Wear OS smartwatches are fundamentally quite similar, but Mobvoi - the company behind the TicWatch S and TicWatch E - has just announced one that could stand out, as it has two screens.

Called the TicWatch Pro, this wearable has both a standard circular OLED display and an FSTN LCD screen. The LCD display is a low power black and white one that sits on top of the OLED screen and when it’s not on it’s transparent, so you can fully see the OLED display underneath it.
