For those who think a watch is just a watch, think again. Still, some would argue that a touch-screen would drain the battery life faster and that an athlete may find it annoying to operate a touch-enabled display, but, while these points are reasonably valid, considering that this is a premium device, this omission can be a deal-breaker for some.
Another type of electric watch was developed by the Bulova company that used a tuning-fork resonator instead of a traditional balance wheel to increase timekeeping accuracy, moving from a typical 2.5-4 Hz with a traditional balance wheel to 360 Hz with the tuning-fork design.
In any case, using Tizen OS, you get the Samsung Health (it provides fitness tracking, including new exercise modes for both indoors and outdoors workouts and can accurately enough detect when the user switches the exercise; it can also track your sleeping time decently well), Bixby (a voice assistant – useful to perform calls or send emails) or the SOS function (tap the Home key three times to send an emergency message to your contacts or perform an SOS call).
In terms of sensors, the Casio WSD-F30 is equipped with a magnetic sensor for direction, a pressure sensor, an accelerometer, a gyrometer and a low-powered GPS (it also is compatible with GLONASS and Michibiki) – unfortunately, Casio decided against adding a Heart rate sensor, which is inexplicable, since you can find it on less costlier smartwatches.
Though most watches of this type have exquisite movements to keep time – mechanical movements are especially popular – there are some timepieces that are classified as luxury watches” even though more attention has been paid to the design than the actual workings of the watch itself.
The battery life was one of the best features of the rugged smartwatch, because, if you disabled the GPS and the heart-rate monitor and used the device only as a watch, you could get up to 2 military watch strap with cover weeks on a single charge (with the GPS on, you would get up to 24 hours and if used in UltraTrac mode (it accesses the satellite once a minute), the battery would deplete in about 60 hours).
