Casio WSD-F30

The Japanese brand Casio is known for its wide range of wristwatches. The G-Shock series of shock-resistant and waterproof chronographs enjoys great popularity among the public. Its logical evolution is the “wiser” Pro Tek Smart WSD-F30 watch, addressed to travelers and adherents of an active lifestyle.

All-protected execution

The wearable gadget is made in the best canons of the all-protective watch genre. The massive body of the model withstands diving to a depth of 50 m and is not afraid of falling on hard surfaces, which is confirmed by compliance with the American military standard MIL-STD-810G. According to the classification of the degree of protection, smartwatches are marked with the designation IP68.

"Sandwich" of two screens

Perhaps the key feature of the Casio Pro Tek Smart WSD-F30 is the "sandwich" of two displays put into service: the first based on an OLED matrix with a diagonal of 1.2" and a resolution of 390x390 pixels, the picture on which is displayed in colour, and the second monochrome. The latter serves to display the current time along with the readings of the built-in sensors: altimeter, barometer and compass. The gadget stays afloat for 30 days when using an exclusively monochrome screen and 2-3 days when two displays work together.

Activity measurements

The operating system on board the model is represented by Google's Wear OS system, which is famous for its user-friendly approach. In addition to the standard functions for duplicating alerts from a linked smartphone, the watch has carefully approached the issue of registering numerous physical activity parameters(running, fishing, cycling, climbing, hiking, etc.). However, they do not have a heart rate monitor, as well as an NFC chip. As moral compensation, the user is provided with support for GPS navigation on colour maps directly from the watch screen, which will help not to get lost in unfamiliar terrain.
