Watch collectors have dubbed it the “Disco Volante,” or flying saucer, due to its distinctive case shape that looks like a UFO. The lot here offered has a very elegant case with fluted lugs, stepped concave bezel and screwed down the case back. The material used is the rarest one, fully in platinum that has maintained its quality throughout all these years with sharp edges and very clear crown. This model features the 12–600AT movement, an engineering marvel which made its debut at the 1953 Basel Fair. The dial is perfect with mat silver background, applied diamond-set hours indexes, silvered dauphin hands, outer minute division perlage and subsidiary seconds dial for the seconds. This very watch is accompanied by a Patek Philippe Extract from the Archives confirming its production in 1955 and its subsequent sale on 30 November 1955 and this very model in platinum is surely one of the rarest and most important automatic examples produced by Patek in the 50s and thus absolutely a real gem to purchase and add to a special collection.
