Rare Waltham Export “Duke” 12s Pocket Watch Movement

A very rare thing and hard to find movement, only 2000 were produced in total, you can find more information on this here.

Movement is not running, I think the mainspring has gone but the balance is good and swings freely, pallet moves and escape wheel tries to move but is stuck probably due to no mainspring power. Winds at 3 O Clock.

Measures 39.8mm at widest point.
