TOMSGUIDE - Mar 12 - Most smartwatches act as companions for your mobile devices. Exetech's XS-3 can work without a linked smartphone, and joins the likes of the Neptune Pine, the Goophone watch and the Watchphone as an independent wrist-worn computer. You can get the XS-3 in Black (White available in the future) for $480 on Exetech's website. Both the XS-3 and the Neptune Pine are much chunkier than Galaxy Gear 2 and the Pebble Steel but they offer more functionality with access to the Google Play store for apps. Both also offer SIM card slots and 3G radios.
