Interesting article over at Wired today http://www.wired.co.uk/article/omega-watch-headquarters-making-design-biel-switzerland All the parts are kept at 15% oxygen levels and collected by robots!
Now I want a Mission Impossible film where Tom cruise needs to survive in a 15% O2 room to steal a rare watch part
Totally do able as it says it's more O2 than Everest'base camp . You need a bigger plot... Motion sensors? Because why not
