Our history & watchmaking

HISTORY & DESIGN

The history and details behind this watch.

Our Royal Army W-10 recreates a lasting classic associated with Britain’s Army, Navy and Air Force.

Its curved case is a tonneau design—“tonneau” is French for “barrel.” This distinctive form was produced by Hamilton and CWC. The watch was designated W10 for the Army and carried a 6B reference in Royal Air Force service. It is a design used by the British military over many years.

H.S. dial

This case-and-dial combination did not exist as a historical original. We have combined the W-10 case with a dial inspired by a Longines watch used by the Royal Navy during World War I.

“H.S.” stands for “Hydrographic Survey.” The dial carries a broad arrow, the maker’s mark “C,” and the naval control number “103” above 6 o’clock. Together, these coded markings give the design its distinctive depth of character.

Five strap choices

Choose from grey nylon NATO, olive fabric, brown Crazy Horse leather, stainless-steel Bamboo, or holeless green fabric. See the selector above for prices and available photographs.

Bamboo bracelet

This traditional British military-style bracelet is made from stainless steel yet remains light and strong. Worn directly on the wrist or over a jacket, it allows the time to be checked quickly—an appealing choice for motorcyclists, too. It can be attached to the watch and adjusted without tools.
