I am about to purchase this watch http://www.chrono24.nl/longines/flagship-chronograph--l47568--id3772320.htm According to buyer around 5 year old --> so i think I need service in the somewhat shirt future. Is a watch only sale no box and papers. IS there something I can use in the buying phase to lower the price a bit? Or is the price already correct. It retails for 6750 but I can find it on different places for around € 3750 new.
