Drawing inspiration from the revered design of DELMA’s Shell Star collection, the Shell Star Decompression Timer is a masterclass in innovation and style. Marrying a blend of state-of-the-art diving technology with time-honored aesthetics, this timepiece strikes a rare balance between functionality, resilience, and elegance. One can’t help but notice its hallmark features: the spade central seconds hand, the signature railway track, and the vivid orange and white indexes that offer clarity at a glance.

Delving deeper into the Shell Star Decompression functions, the decompression timer functionality is a nod to the groundbreaking Swiss research carried out during the 1950s and 60s. This feature plays a pivotal role in diver safety, as it provides clear visual cues for when decompression stops are essential. Designed for optimal performance, the watch excels in conditions ranging from 0 to 700 meters above sea level. Complementing this is the coordinating blue unidirectional bezel, allowing divers to meticulously track their dive durations.

At the 12 o’clock position, the vertical scale signifies the dive depth, and the stark white markings on the rings offer an unmistakable indication of when decompression stops are needed. Beyond its sophisticated features, the watch boasts an impressive robust construction, paired with a helium escape valve, ensuring it can effortlessly handle water pressure up to 500 meters or approximately 1650 feet. Elevating its stature further is the solid stainless steel bracelet, making this timepiece not just an essential diving tool but a style statement in its own right. For those intrigued by the intricacies of horology, the automatic movement can be admired through the watch’s transparent case back. This watch, undoubtedly, is a testament to DELMA’s commitment to craftsmanship, innovation, and style.
