You know the story how Rolex patented the helium relief valve on watches? Allow me to bore you anyway…
During some early saturation experiments at the old Navy Experimental Diving Unit in Washington a couple of guys were decompressing. The chamber was small so they were sitting on a bench with their hands folded between their knees. All of a sudden the face of a Rolex watch blew out and hit a guy's inside thigh hard enough to make a serious edema, besides hurting like hell.
They did some research and found that Helium molecules will leak through all known transparent materials. The gas slowly leaked into the watch, which could easily take the external pressure but was never designed for internal pressure. They called Rolex, they put a tiny relief valve in a new watch with a deeper rating, named it the Sea Dweller, and called their Patent lawyers. The 17 year patent is long expired now.
The guy with a 1½" round scar on his leg was one of the Diving Officers when I was getting qualified, several years latter.
and the battery(s) in computers WILL fail at some point rendering your dive over. In 32+ years of diving I've seen this happen more than a few times to others and myself. My Rolex Submariner has never let me down and thus I've never had to call a dive due to battery power loss.... Sometimes a little old school redundancy is a good thing..
