In fact, I fully wound the stand-alone movement and observed that it ran for 125 hours before coming to a stop so we know that the watch is capable of storing enough energy and operates with sufficient efficiency to deliver the full 5-day power reserve with a little left in the tank. When manually winding this watch it takes more than 100 turns of the crown to fully wind it up, where most watches would be fully wound with about 40 turns of the crown. Before addressing this I think it is important to note that it takes a lot to fully wind a double barrel (5-day power reserve) watch. This 7-day test brought to light one of the first complaints I have heard from individuals who have purchased this watch and that is that they don’t seem to get the full 5-day power reserve as advertised by Oris.
