ABOUT THE A-11 AUTOMATIC 44
The A-11 Automatic was originally developed in collaboration with members of the Swedish Submarine Flotilla. Designed to capture the essence of Swedish submarines, it draws inspiration from details and equipment found onboard, such as the periscope sight in the dial. Paying tribute to Sweden’s history of submarine manufacturing, the caseback features the silhoutte of the iconic A-11 submarine.
Based on the original Frogdiver 44, the A-11 offers a more affordable alternative to the large, ambitious model—without compromisingm quality or rugged design. By removing the analog depth gauge, the watch features a more prominent dial with improved readability. The watch is a bold and durable timepiece built to withstand tough environments.
Powered by a reliable Seiko automatic movement, the watch is wound through the screw-in crown or natural wrist motion, offering a 41-hour power reserve. The bezel is designed for easy operation, even with gloves, and
the grippers can be removed if needed. Luminous indices and hands provide excellent visibility in low-light conditions, standing out against the dark dial.

Project A-11
Sweden's submarine manufacturing dates back to the late 1800s, and by the early 1900s, the country had become a leader in modern submarine technology. During the Cold War, the demand for cutting-edge submarines grew, leading to the development of Project A-11—a mission to create five state-of-the-art submarines capable of meeting new military requirements.
The result was the Sjöormen-class (Swedish for "Sea Serpent")—a fleet of highly advanced submarines that set new standards in design and performance. These were Sweden’s first truly modern submarines, featuring a teardrop-shaped hull and pioneering the now-standard X-shaped rudder at the stern. At the time of their launch, they were considered among the most advanced non-nuclear submarines in the world.
The Sjöormen-class entered service in 1968 and remained in operation until the late 1990s, after which they were transferred to the Singapore Navy. Following modernization, they continued serving until 2024.
