Response to Sorry, but that's rubbish. ;-)
Pure water can not get colder than 0 C.
It phase changes (to ice) and then the ice gets colder, or you can make the water impure by adding ions or liquids either of which will depress the freezing temp.
As to why you want to subject a watch to this--no opinion.
