What are the two things that you never leave your house without? It’s your keychain (with the keys obviously) and your watch, but my question is why carry two things when you can have both in one. Actually it’s not my question it’s the brainchild of Francisco Cubides. While many do not pay attention to the type of keychain they use, some are rather more conscious, which is why this elegant concept of a Keychain Pocket Watch is guaranteed to turn heads. It looks like an ordinary cube at first glance, but pulling the cord will display the current time even when blanketed in darkness.

The semi-transparent cube measures 20mm square and is powered by a couple of cell batteries.
