Casio just announced a beefier version of its Pro Trek WSD F20 smartwatch. The Pro Trek WSD F20S adds a sapphire glass display, ion plating on the buttons, screws and buckle, and a new black case with blue details and a glossier surface.
This goes on top of an already rugged Android Wear 2.0 Pro Trek WSD F20 with GPS, MIL-STD-810G military rating and a waterproof capability of 50 meters.
The Casio Pro Trek F20 is a limited edition and will come in only 500 units with a likely price tag of $500.
The design could use a bit of help, but Casio makes the most reliable watches IMO. I just gave away my last expensive watch, a relatively new middle-range Omega, which was the least reliable watch I've ever had.
500 $ Casio, lol. it looks like a childs watch.
