Accompanied by a Patek Philippe Extract from the Archives confirming production of the present watch with diamond hour markers in 1952 and its subsequent sale on January 28th of the following year.
Production of this model, reference 2443, was introduced in 1948. Only a few hundred were made in gold and very few examples were produced in platinum.
To the best of our knowledge this watch has never before been offered in public.
Reference 2443 is illustrated in Patek Philippe Wristwatches by Martin Huber & Alan Banberry, 1998 edition, page 134. Calibre 9'''90 is illustrated in the same edition on page 129.
