Apple Watch and Android Wear is cool and everything, but the best wrist wearables are often made from Arduino boards and some tinkering, much like this super great Enigma watch.
Although known notoriously as the uncrackable cryptography tool used by Germany during World War II, the Enigma Machine was eventually undone by the father of artificial intelligence, Alan Turing And ever since last year’s The Imitation Game, Turing has enjoyed some much-deserved popularity, even the CIA loves him.
