Rare Vintage Universal Polerouter Painted Dial 0

The dial/watch was commissioned in the 1950's by a Maltese nobleman at Universal directly to produce this watch with the painted enamel dial image of St. Paul the Patron Saint of Malta for the Archbishop of Westminster (head of the Catholic church in England and Wales), His Eminence Cardinal William Godfrey in 1960 in recognition of Cardinal Godfrey's role during the Second World War and up to his appointment as Archbishop of Liverpool in 1953.The inscription on the rear confirms this. I have been in touch with Universal who have confirmed by email producing this special order piece in 1958 but unfortunately their records for the time are incomplete and were unable to provide information on the artist or anything else. Having seen cloisonne dials from Universal this is the first painted enamel dial I've seen. I am selling this and other watches in my collection to focus on my main interest..vintage Pateks. I would like USD $ 12,000 for this timepiece. Thanks Roni
