Note: Movement 526606 is a hunting movement in a hunting
case with the stem at 3:00 position.To my
knowledge the 940 is an openface movement & the
941 is a hunter movement.Please correct me if I am
wrong.
Curator Response: After evaluating your photos on eBay, it appears that you have an interesting conversion dial. The movement is openface. However, the dial places the seconds bit at the 9:00 position, allowing the watch to be mounted in a hunter case.
