Damasko Watch DSub3 Rubber Strap Sport. Functional reliability under water pressure of up to 300m, good readability even in adverse visual conditions and accuracy are indispensable features of a reliable divers watch. The DSub from DAMASKO goes even further. The sporty, masculine series is made using special submarine steel. This material is characterised not just by extreme solidity and its non magnetic quality, but additionally by its unique corrosion resistance even when used in sea water for long periods. At the same time, submarine steel is extremely crack resistant due to its ductility. The unidirectional rotating bezel with integrated ceramic ball raster elements and a white orange coloured diving scale allows the elapsed diving time to be read reliably, which enables exact planning of the vital decompression phases. The patented DAMASKO crown system can be used under water without any problem.
