Delma 41501.670.6.044 Shell Star Decompression Timer Automatic Watch

The Delma Shell Star Decompression Timer merges precision engineering with professional diving capability. This automatic timepiece draws from DELMA's storied heritage, featuring signature design elements including a spade seconds hand, railway track indices, and contrasting orange and white markers. The integrated decompression timer-rooted in Swiss diving research from the 1950s-60s-provides essential safety information at a glance, displaying when decompression stops are required during ascent. The unidirectional blue bezel facilitates accurate dive timing, whilst the dial's vertical depth scale and ring markings offer critical decompression guidance. Built for depths to 500m with a helium escape valve and robust construction, this instrument delivers genuine technical functionality. The transparent case back reveals the automatic movement, whilst a blue rubber strap completes this sophisticated diving tool designed for serious underwater exploration.
