HYT watch uses sealed liquid to tell the time

Luxury Swiss watch start-up HYT is showing off its latest range. Using technology originally developed by Nasa, the watches tell the time by showing the progress of bright oils along tubes.

HYT makes fewer than 500 pieces a year, and charges up to 280,000 Swiss francs ($283,000; £191,637) for them.
