The RJ 21 nano timepiece doubles up as a time capsule.

Holding the world record for the smallest micro-engraving ever done, this timepiece is able to store the information equivalent of 400,000 paperbacks on one side of an A4 page.

Hence, the size of each word is approximately ten times smaller than a hair diameter.

The stored data can be viewed under an optical microscope and can be kept for up to an impressive 2 million years.
