Has Doxa's US Patent N. 3505808 expired? Reason I ask they like advertising this on there watches. "DOXA’s patented no-decompression dive table bezel (US patent N. 3505808)." I did some research I think it has but i'm not sure. I would like to see this feature on other brands or probably my own watch design one of these days. I went with the worst case scenerio 20 years.   source: http://www.google.com/patents?id=IztlAAAAEBAJ&printsec=abstract&zoom=4&source=gbs_overview_r&cad=0#v=onepage&q&f=false
