A fine British WW1 MK V Invicta aircraft - pilots cockpit watch.
Circa - 1916 / 17.
Dial - 30hr - Non luminous - Mark V
B D 1578.
In original condition, having a perfect black enamel dial with clear earlier font.
The Swiss movement is well signed - Invicta Mfg Co. La Chaux De Fonds Switzerland.
The outer case is in good condition, with some small imperfections. There are some
scratches where the outer cover has been historically removed.
Unusually - the extended stem has not been drilled for a bow, as many WW1 watches
were - post war.
The watch is in working order, keeping good time.
