This is a near pristine Patek Philippe ref. 3800/1 classic (not jumbo) 1998 NAUTILUS with box and papers and was just FULLY SERVICED in April 2014. The sparkling case and bracelet are beautiful. The steel case with sapphire crystal and caliber 330SC PATEK PHILIPPE gold rotor movement measures 37mm. This is not the large version of the watch, but the more subtle and lovely smaller example. The blue dial changes from bluish to black depending on the lighting and angle of view. You could not ask for a finer representation of this watch. Myself and many dealers believe this discontinued PATEK 3800/1 will dramatically rise in value in a very short period of time. You will thank me. A great investment in time @ only $12,500.
