The PRT-B50 is a new PRO TREK model that can connect to a smartphone app via Bluetooth. Unlike some other Casio watches with this ability, however, this new product has a non-digital watchface. Its physical hands can be used to do things such as point to a saved location.
Deirdre O Donnell,

The PRT-B50 is Casio's latest PRO TREK model that can also use Smartphone Link, by which some of its functions can be controlled or co-ordinated using the brand's Connected app. This is done via a Bluetooth module. However, rather than having a full LED display or a digital face like most similar watches, the PRT-B50 is an analog watch. It has physical hands, as well as a small LCD display along the bottom of the face.

This new Casio also comes with a compass-bearing sensor, a barometric pressure sensor for altitude and a  temperature sensor. This allows for such features as Route log, which incorporates the PRT-B50's altitude data and GPS data from a connected phone.

Location Indicator is activated when the watch's buttons are pressed to save its current position using the PRO TREK Connected app. Thereafter, this location is accessed when the new PRO TREK'S second hand swivels around to point to it, while the distance back to it is shown on the LCD.

The PRT-B50 also uses Smartphone Link to automatically adjust its time and altitude 4 times a day. It can also activate a phone-finding tone in a connected device. Like many other Casios, it also offers world time in 39 cities, water resistance up to 100 meters, a full LED backlight, a 1/100th second stopwatch, a countdown timer and a full auto calendar.

This PRO TREK is mostly directed at men (clearly those who enjoy hiking or similar pursuits) and comes with black, blue or orange casings. It will be sold at a recommended price of US$200 through select stores throughout the US later in 2019.

I became a professional writer and editor shortly after graduation. My degrees are in biomedical sciences; however, they led to some experience in the biotech area, which convinced me of its potential to revolutionize our health, environment and lives in general. This developed into an all-consuming interest in more aspects of tech over time: I can never write enough on the latest electronics, gadgets and innovations. My other interests include imaging, astronomy, and streaming all the things. Oh, and coffee.
