A smartphone app, an internet search or even some quick calculations are all effective enough ways of working out the time in other locations around the world, but perhaps aren't as elegant as the World Clock from Korean design firm Elevenplus. This stylish timepiece can quickly show you the time in 24 different time zones, needing only a little push in the right direction.
Powered by a single AA battery, the pocket-sized World Clock measures 85 mm (3.3 in) in diameter and weighs 144 g (5 oz), so was seemingly designed with the country-hopping traveler in mind. In and of itself, it's an impressive enough device, but it a nifty built-in rolling mechanism is what gives the World Clock a point of difference.

Engraved at intervals around its cylindrical body are 24 different time zones. With the time set for the user's current location, a user can roll the clock so that the time zone they seek aligns with the traditional 12 o'clock position. But because the hands spin freely of the clock face, they remain in the same position while the numbers rotate with the body, displaying the time in that particular location. Releasing the clock will see it roll back to your time zone.
Technologically sophisticated? Not overly. Clever, tasteful and kind of practical? We reckon so. You can nab your own World Clock over at online retailer Leibal for US$50. It is available in grey, blue and orange.
