This unassuming Grana military issue c.1945 forms part of the so-called ‘Dirty Dozen’ wristwatches made by 12 Swiss manufacturers for the British army. It was consigned for sale at Trevanion & Dean on May 19 by a lady whose husband had been given it to keep good time while working on a building site 60 years ago.
The Grana is considered the hardest to find of the Dozen, with perhaps as few as 1500 made by this otherwise routine maker.
