wildfire2004 0 Posted August 4, 2012 (edited) I am a newbie, so forgive me for any queries that seem obvious. I recently bought a rep IWC Portuguese 3714 - details are: Asian 7750 Valjoux Working Chronograph movement, 28800 bph One-piece solid pullout crown with o ring Sapphire crystal The watch is very solid - however, from time to time it stops for no reason it stops and I have read that secs at 6 and 9 is an issue with these watches. When I wear it is OK'ish and keeps time reasonably. When on the table over night - it seems to have only 4 -5 hours of power reserve. Does this need servicing ?
