DELMA Shell Star Decompression Timer

The Shell Star Decompression Timer presents sophisticated diving technology built upon the collections’ cherished design. Based on research of the 1950s and 60s by Swiss dive pioneers Hannes Keller and Albert Bühlmann, it uniquely takes into account the need for multiple decompression stops for deeper and longer dives at different altitudes. The decompression timer is complimented by essential features of the Shell Star collection such as a spade central seconds hand, the railway track and vibrant orange and white indexes. It is offered with a black, blue or orange unidirectional bezel with either a stainless steel bracelet or rubber strap.
