When NASA's Apollo spacecraft launched to the moon, it had on board two briefcase-size computers that for their day would normally have required enough floor space to fill a couple of rooms. The compact devices were small, but had enough processing power and memory to guide the astronauts from Earth to the moon.
Fifty-five years later, the British startup Apollo Instruments has been able to shrink the Apollo Guidance Computer (AGC) even further — to the size of a wristwatch. Now, anyone can wear the display and keyboard system, or DSKY (pronounced "disk-key"), that astronauts used on the command and lunar modules.
The DSKY Moonwatch is more than just a novelty timepiece; wearers can interact with it just like the Apollo crews did and fly to the moon (rocket and spacecraft not included).
