Casio G-Shock GDF100 with Altimeter

The 2011 Casio G-Shock GDF 100 comes equipped with a two-in-one front-facing pressure and temperature sensor. Although its exterior styling is light years away from something that is usually associated with a 'pilot's watch', it is (rather unsurprisingly, I would say) also way more usable for those who actually fly something more powerful than an office chair. People who prefer an active lifestyle will probably like one, too.
