For its 120th anniversary, ZRC unveils the SECURICODE collection, a tribute to its heritage with three vintage-inspired models. The name evokes ZRC’s adventurous spirit and its long history in professional diving, dating back to 1958 when the brand created the iconic Grands Fonds S1 for the French Navy. The SECURICODE Diver 300 reintroduces key design elements from the original S1, including bold Magnum-type hands and a lollipop second hand, both illuminated by Super-LumiNova®. Its guilloché brass dial, protected by a sapphire crystal, shifts to marine hues in sunlight. With a 39 mm case and water resistance up to 300 meters, it combines timeless design with modern performance. The SECURICODE Diver 300 Steel features a guilloché brass dial in a stainless steel case with a brushed-finish bezel and an expansion band powered by the SW200-1 automatic movement. The Steel/Ceramic version adds a date display at 3 o’clock and a scratch-resistant ceramic bezel paired with a retro Tropic rubber strap. The limited edition Diver 300 Bronze/Ceramic celebrates the collection with a forged bronze case, Super-LumiNova® eggshell hands, and a vintage leather strap.
