Say goodbye to the hassle of dead watch batteries with Citizen's Eco-Drive Perpetual Calendar Watch.

Unlike other automatic watches that depend on direct sunlight, the rechargeable battery inside this stainless steel watch can revitalize itself whether you're inside or out.

The option of the indoor recharge would be a particularly useful feature if you're one of those poor fools who either works too much, or lives in some godforsaken place like Northern Greenland during the winter.

Either way, rest assured -- you'll never lose track of the time. ($319 from Bluenile.com)
