The test in water is passed.
PS! The ring fell off (where the letters N, S …) in six months! Lost in the woods in winter, in spring, this ring found in the grass by chance)) This ring is kept as a double-sided scotch, i.e. very not reliable. Be sure to glue this ring on the new watch until the ring is lost.
