If you travel, a world timer watch is a very handy complication. Switch cities, and you can easily switch time zones on your watch. But what if you want it done for you? That is where GPS watches come into play. Not GPS as in tracking watches, but GPS watches that update their clocks based on where they are in the world. Since they only update every other day (or on command), the receiver part uses little energy, so these are not power hogging watches like a GPS tracker would be. Now on Kickstarter is a new brand hoping to get into this technology with the first four Artstate GPS Solar Watch models (OK, only 2 are solar, but they are all GPS). This new brand is significantly less expensive than the other mainstream brands that are available.
