Key Features Inspired by the iconic 1977 Challenge Diver, famously known as the Fujitsubo Diver, this model celebrates the 35th anniversary of the PROMASTER brand. The original watch, lost in the ocean and later found on a beach, still ticking and covered in barnacles, exemplifies durability and exceptional design. This anniversary edition captures the essence of the blue ocean and white sands of Long Reef Beach in Australia, featuring blue accents on the dial and bezel, complemented by a contrasting black aluminum ring. The case and bracelet, treated with Duratect Platinum, shine with a gleaming, almost transparent silver hue. The 35th Anniversary limited edition logo engraved on the case back adds a touch of exclusivity to this remarkable timepiece. The Cal. 9051 movement uses anti-magnetic materials for the balance spring and surrounding components, enhancing the watch's overall magnetic resistance. This new Promaster Auto Diver maintains performance even when placed just 1 centimeter from a device emitting a magnetic field of 16,000 A/m. It is also resistant to magnetic fields from everyday devices like smartphones and can be used aboard ships with magnetic compasses. In addition to its impressive magnetic resistance, this watch boasts ISO-compliant water resistance up to 200 meters. When fully wound, it runs for 42 hours with a daily accuracy of -10 to +20 seconds, showcasing solid performance for a mechanical watch. The hour hand, minute hand, and indexes feature a luminescent coating for high visibility. The case, with bold trapezoid indentations, is both stylish and functional, providing a rugged look and a secure grip when using the bezel. Constructed with a two-piece structure, it uses Super Titanium™ with CITIZEN’s proprietary Duratect surface-hardening technology, making the watch incredibly light for its size. The rugged aesthetics of this model are further enhanced by an intricate, almost stud-like pyramid pattern on the bezel and dial, with shades that shift depending on the viewing angle.
