This is a vintage (unused) new-old-stock 1960s Vulcain skeleton watch measuring an oversized 41mm across and 11.89mm thick, providing much wrist coverage due to its large size. The gold-plated case with see-through front and back displays the automatic winding movement, which was just cleaned and is accurately keeping time. Notice the signed original crystal and winding crown. This watch came from unused old stock that was not sold from the 1960s! Any marks on this watch are from handling over the years only. It is very uncommon to find a large vintage watch such as this.
