The watch has a round dial,single winder and date window in the face.
The second hand appears to move twice per second.
The watch spent some time buried in the ground as it was disinterred
when a drainage ditch was being dug around a tent in the bush. After
the dirt was cleaned of and the watch wound it started and has kept
time ever since. Any info welcome.
