Among the slew of smartwatches making its way to this week’s Baselworld show is the Casio PRO TREK Smart WSD-F20S watch. This is a limited-edition model based on the PRO TREK Smart WSD-F20, now featuring a black and blue design that adds a scratch-resistant sapphire crystal, as well as ion plating on the buttons, screws and buckle hardware. The core features remain the same, which include a 1.32-inch dual layer LCD 320 x 300 touchscreen display, Bluetooth 4.1 and Wi-Fi connectivity, and low-power GPS. Powered by Android Wear 2.0, the watch is water resistant down to five meters, with a battery that lasts more than one day through normal use. The WSD-F20S will be packaged in a special case with a triangular lid and will be limited to 500 units.
