Actually, the helium valve is useful for divers that goes at great depths for long period. Before reaching surface they have to spend long period in decompression bells which use a mixture like trimix, which contains helium. Because the helium molecules are very small, they go through the gaskets of the watch and increase pressure inside. To avoid damage like crystal pop out, you unscrew the valve to release pressure. Hope it helps. Last edited on Sun Jul 5th, 2009 02:43 pm by DM71 |
