About 10 years ago we presented the AQUAMATIC 1 to our audience. The success was overwhelming and we would like to do it again with our new AQM 4. The AQM 4 is equipped with all requirements needed for a professional diver watch. The matt steel case withstands water pressure up to 800 meters. For gaining maximum security we certified the case with only 500 bar per 500 meters. Before delivery every diver watch case is tested up to 80 bar at Schaumburg Watch.
