Accompanied by Patek Philippe Extract from the Archives confirming production of the present watch in 1964 and its subsequent sale with enamel painting "The Mosque" by S. Rohr on 21 November 1974.
This watch is the only example of a reference 864 known to exist. Besides featuring an incredibly fine enamel scene on the back, it is important to mention that it is fitted with a impressively small 16''' lignes movement. To the best of our knowledge, no other watch of post war production with the present complications has left the manufactury with such a small caliber.
Mrs. Suzanne Rohr is one of the last artists able to perpetuate the supremely exacting art of miniature painting on enamel. Mrs. Rohr, who celebrated 35 years of collaboration with Patek Philippe in 2002, reserves her talent for the company. Since the 1960s, when Patek Philippe re-launched the production of watches with enamel miniatures, Mrs. Rohr has been entrusted with the creation of only three pocket watches a year. In her hands, the secret alchemy of the colored enamels offers a second life, of unequalled depth and finesse, to some of the world's greatest art treasures.
These rare Patek Philippe timepieces are, in general, made to special order with the subject matter to be represented chosen by the client. They often include celebrities, landscapes or famous buildings.
The present watch and its illustration of the Mosque adjacent to the College at Wattayah, Oman, was most probably ordered by or for a dignitary of the Sultanat of Oman.
Oman has been ruled since 1970 by Sultan Qaboos bin Said Al Said whose extensive modernization program opened the country to the outside world.
One of his first priority was to set up educational establishments which spread dramatically across the Sultanat. By 1975, there were 262 schools and institutions, certainly including the College at Wattayah and its mosque depicted on the present watch.
