Accompanied by Patek Philippe Certificate of Origin & Warranty and Extract from the Archives confirming production of the present watch with inlaid platinum initials W.J.K. in 1917 and its subsequent sale on 17 December 1918. Furthermore delivered with the original fitted brown leather presentation box.
To the best of our knowledge, the present watch is the only Patek Philippe carillon minute repeating split seconds chronograph watch ever offered publicly.
Its unusual split seconds chronograph mechanism is operated by three buttons instead of the, more common, two.
The carillon repeating mechanism is more complicated than the better known quarter or minute repeating function and is more frequently found in clockwatches. It features three or four gongs instead of only two. The quarter hours of the present watch are stroke on three hammers onto three gongs.
