This is a high end calibre I understand. However, the watch I have with it is not as accurate as some of the lower spec. Seiko calibres (if you believe what others write) 9 to 10 secs. slow a day on the wrist or a winder is not impressive in my opinion. What experience do other owners have? Can it be improved? NB: It is still under warranty so maybe I should just go back to the dealer? Thanks
