Montblanc releases the Timewalker Urban Speed e-Strap, suggesting that watch straps can be much more than a band that keeps your watch from falling off your wrist. The new watch is the luxury brand’s first foray into digital wearables. Not only can the watch itself tell time (as it should), the strap can be used with any analogue watch and track activity, control music, send and receive message and phone notifications, and can also track itself. The fact that it will be compatible with both android and iOS adds to its charm.
