Today we have a treat for you in the form of an extremely rare Patek Philippe split seconds chronograph. This is the reference 1563, of which only three known examples exist, the most famous of which once belonged to Duke Ellington and now resides in the Patek Philippe museum in Geneva. This 1563 has a few features that set it apart from the other two as well, further upping the ante. If you couldnt tell, this is one were pretty excited to share.
