dirt and foreign matter. In rare circumstances, accumulated dirt, foreign matter may cause
irritation with the skin. If you notice this, discontinue wearing the watch and consult your
physician.

synthetic rubber strap (polyurethane) and/or metal case using a soft brush and mild soap. Be
careful not to allow moisture on the case if your watch is not water resistant.
