Keychain Pocket Watch

Everybody carries at least a set of keys with them, be it car, office, or house keys. 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. Kudos to Francisco Cubides for this concept – now will someone work on a commercial product already?
