Damasko Watch DSub1 Leather Rubber Yellow. Functional reliability under water pressure of up to 300 metres, good readability even in adverse visual conditions and accuracy are indispensable features of a reliable divers watch. The DSub from Damasko watches 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, special material flexibility under load. The unidirectional rotating bezel with integrated ceramic ball raster elements and coloured diving scale allows the elapsed diving time to be read reliably, which enables exact planning of the vital decompression phases. The patented Damasko watches crown system can be used under water without any problem.
