Well, it’s useful for commercial divers only; that too, only them doing very deep saturation diving. You need to live underwater for that, in habitats filled with a mixture of breathing gases, one of which is helium. The helium molecules are small enough to pass through the water\/humidity protection of the watch and expand as it surfaces due to dropping pressure. This damages the watch. The valve, when opened, lets the helium escape.","brand":"Ratio","offers":[{"title":"Default Title","offer_id":48610668183880,"sku":"1066KE20-33VA-BLK-var-NATO1","price":210.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0828\/8288\/8008\/files\/1066KE20-33VA-BLK-var-NATO1.jpg?v=1718350125","url":"https:\/\/www.citywatches.co.uk\/products\/ratio-free-diver-helium-safe-nylon-automatic-divers-1066ke20-33va-blk-var-nato1-1000m-mens-watch","provider":"CityWatches.co.uk","version":"1.0","type":"link"}
