The Shell Star collection traces its origins back to 1975, when DELMA introduced its first professional dive watch under this iconic name. This pioneering timepiece set a benchmark for the brand, inspiring a legacy of robust and reliable divers’ watches. The latest Shell Star Big Date stays true to its heritage while integrating modern advancements. Built for the toughest conditions, its brushed stainless steel case features a screw-down crown for enhanced durability, a helium escape valve, and an impressive water resistance of 500 m / 1650 ft. The bold, applied luminous orange indexes and a black unidirectional bezel ensure optimal readability in any environment. A striking blue gradient dial is complemented by an orange-framed big date display at 12 o’clock, balancing functionality with a distinctive aesthetic. Designed for both everyday wear and professional diving, the Shell Star Big Date comes fitted with a resilient stainless steel bracelet. Meanwhile, the automatic movement, visible through the transparent case back, underscores its precision and craftsmanship making it a true companion for underwater adventures and beyond.
