The Delma Shell Star Decompression Timer merges heritage diving aesthetics with advanced technical capability. This automatic timepiece draws from DELMA's iconic Shell Star lineage, featuring signature design elements including a spade seconds hand, railway track indices, and contrasting orange and white markers. The standout decompression timer function—rooted in Swiss diving research from the 1950s-60s—provides essential safety information for divers, with depth readings at 12 o'clock and clear decompression stop indicators via the dial's white ring markings. The unidirectional rotating bezel enables precise dive timing, whilst the helium escape valve and robust stainless steel construction deliver 500m water resistance. Optimised for depths up to 700 metres above sea level, this instrument combines professional-grade functionality with refined watchmaking, completed by a solid steel bracelet and exhibition caseback revealing the automatic movement within.
