With Patek Philippe Certificate of Origin and Extract from the Archives confirming production of the movement of the present watch in 1931. It was encased in 1964 and sold on 25 June 1968.
The present watch is one of the greatest post war designs for complicated pocket watches and is not only fascinating through its complex calendar and repeating mechanism but captivates also with its wearable size. Research reveals that this watch is the only example of reference 844 known with the prestigious "Tiffany & Co." retailer signature and probably one of only three watches of this reference still retaining its original certificate.
Reference 844 is not only appealing to the pocket watch collectors but also to the wristwatch collectors who recognize the DNA of reference 3448 such as the edged bezel, the dauphine hands and the baton hour markers, rendering this model a typical "child" of the 1960's.
A similar watch is illustrated in Patek Philippe by Martin Huber & Alan Banbery, p. 228, pl. 211.
