BRAND HISTORY

Grenchen


The story of Grana dates back to 1888, when Adolf and Alfred Kurth founded a small watchmaking workshop in Grenchen, Switzerland. Initially, the company produced watch movements and components before expanding into complete timepieces.

Grana is now owned by Société des Montres West End SA, an independent Swiss watchmaking company with its own workshops based in Leytron, in the Swiss Alps.

Manufactured and distributed to the British Army starting in early 1945, the WWW watches (Watch, Wrist, Waterproof) were produced by twelve Swiss manufacturers, which is why collectors often refer to them collectively as "The Dirty Dozen."


Only around 1,500 Grana WWW wristwatches were made for the British Army during World War II. As a result, the Grana WWW has become known as the "holy grail" among military watch enthusiasts, many of whom aim to complete their collection of all twelve "Dirty Dozen" timepieces.
