This video of a watchmaker in action is mesmerising

Seriously. We could 'watch' this all day (sorry).

German timepiece maestros Nomos Glasshuette - who specialise in traditional mechanical watches - have become surprise internet stars after a clever video of their craftsmen in action went viral.

The video, entitled 'Look over the watchmaker's shoulders' is a mesmerising glimpse into an almost-lost art, the precision of which is mind-boggling.
