With the PRO TREK WSD-F21HR you can fully concentrate on your sporting activities - the clever Smartwatch takes care of the rest. The rugged outdoor watch is ideal for trail running, trekking and cycling, and thanks to GPS, colored offline maps, a heart rate monitor and many practical apps and functions, it gets you quickly to your destination.
Heart rate measurement
An optical sensor on the case back of the watch measures the heart rate on the wrist by means of an LED. The measured values are displayed on the watch. Use these data for your training, be it to control the pace of your activity or to increase your endurance. In addition to your current heart rate and the maximum and minimum heart rate per day, it shows your training intensity in the form of a heart rate zone over five different levels.
Leave your smartphone at home! This smartwatch is equipped with the Wear OS by Google operating system and features integrated GPS technology, allowing it to operate completely independently from your mobile phone. The smartwatch's GPS enables you to determine your location and trace the route you've travelled.
The WSD-F21 provides map data from OpenStreetMap as well as running and walking routes from Mapbox. This data can be used without a mobile phone or Internet connection — simply download a full-colour map before you begin your activity. This means that your location can also be determined when the watch is offline. There is a wide range of different map designs to choose from, such as topographic maps, maps for water sports enthusiasts etc. You can also use the Location Memory function to manually add a marker to specific locations, e.g. a good fishing spot.
Wear OS by Google
To connect the CASIO watch to a smartphone, the Wear OS by Google operating system must be installed on the device. Wear OS by Google offers a variety of pre-installed apps for outdoor activities. Additional compatible apps can be installed on the watch from the Google Play Store if desired.
Wi-Fi (IEEE 802.11 b/g/n)
If Wi-Fi is enabled on your watch, it will automatically establish a connection to a known, available Wi-Fi network (if the watch is not connected to your smartphone via Bluetooth).
The watch is equipped with energy-saving Bluetooth technology, which offers power-saving data transfer at the push of a button. The watch can connect to a smartphone wirelessly via Bluetooth, enabling access to a wide range of useful functions.
The MIL-STD-810 is a U.S. military technical standard that specifies environmental test conditions for military equipment. The standard defines tests for the compatibility of equipment and devices with extreme temperatures and air pressures, solar radiation, humidity, chemicals, acceleration forces and vibrations.
Double LCD (320 x 300)
The display consists of two overlapping, independent LCDs. The monochrome display provides an excellent level of readability, even in difficult lighting conditions. The colour display can show graphical or colourful measured data in an optimal way and provides a clear overview of the content.
Make your daily life easier using practical voice commands spoken directly into the microphone on your watch. For example, you can start a Google search by saying "OK Google" — without the need to touch the display, or even take your smartphone out of your pocket. Many actions can be performed via the microphone using voice commands.
