I'd like to buy one, can someone tell me which factory produces the most accurate version? The annual calendar works as on the gen? Does it need resetting only once per year (at the end of February)? How big is the power reserve without winding the watch? What if I manually wind the watch, can I have a real 7 days power reserve? Someone can explain me this aspect? What about the movement, is it prone to breaking or is it durable enough? Thanks.
