The A-5 UDT was made to address a longstanding challenge faced by divers: dependable timekeeping underwater. Inspired by the original USN BUSHIPS design, this rugged dive watch stands out with its oversized crown and durable steel case. During WWII, Underwater Demolition Teams relied on this design as the only reliable way to ensure their watches remained water-resistant on prolonged missions. Praesidus has introduced a fresh take on the classic black dial with a striking sunray blue dial, which shimmers in the light to reveal a rich blue hue. The standard white indices have been updated to a light blue, which is luminous for visibility, giving the watch a unique and contemporary flair. The A-5UDT Blue Sunray comes with a blue tropic rubber strap that features a vintage criss-cross texture for extra comfort on the wrist and perforated holes for breathability. It dries instantly and is resistant to all types of liquids, maintaining the rugged vintage look while enhancing comfort. Or with a choice of a stainless steel beads of rice bracelet.
