The RN81

Refining Britain's next generation of military dive watch

Following the successful introduction of the original 1980 Royal Navy Diver, the 1981 model refined the design, revising the dial, hands and movement. For the Royal Navy, evolution was never about changing the character of the watch, it was about improving reliability, serviceability and long-term operational performance of a proven military instrument.

The 1981 Automatic Diver preserved the qualities that mattered most while remaining faithful to the Ministry of Defence requirement that established CWC as the Royal Navy's professional dive watch supplier.

Not a reinvention.

A refinement of a proven military design.

This RN81 model is a faithful recreation of that issued watch, remaining true to the original military specification, combining proven design with modern Swiss manufacturing, sapphire crystal and contemporary luminous materials. The robust and durable Sellita SW200-1 top grade movement ensures accurate timekeeping.

While materials, manufacturing and technology have evolved, its purpose has not.

This is not an homage.

It is a recreation of a watch with a genuine place in British military history.
