1950S Longines Greenlander made for the British army part of the "Dirty Dozen"

| | | mm

The Longines WWW (Waterproof Wrist Watch) is widely considered the most refined of the "Dirty Dozen"—the twelve watches commissioned by the British MoD during WWII. Known to collectors as the "Greenlander," it features a larger-than-average 38mm stepped case and the superb in-house Calibre 12.68Z. With its Broad Arrow marking and patinated radium dial, it is an authentic piece of military history that remains incredibly wearable by modern standards.
