Just stumbled on the Watchmaker website, sorry if someone else has posted this but the boss is around at work and I have to be covert. http://www.alfredcooney.com/

Edit. Sorry I thought the video might be on there but i can find it. :-(

Many thanks, Martin! To be sure, this is the set designer's site with some production photos. There is no XL H1 video to be downloaded there. But it's still pretty interesting nonetheless.
