Watchville
Setting the time on your watch is simple enough — after all, your phone is probably showing a pretty close approximation right now. But if your timepiece demands more accuracy or features than your phone offers by default, take a look at Watchville. Designed as a must-download for watch aficionados, this handy app offers a number of time-focused tools, including an atomic clock, a leap year indicator, UTC time, and moon-phase setting tools. In addition, it shows aggregated news from a number of watch blogs, so if you're really into timepiece collecting, it'll keep you up to speed.
