Patek Philippe The Stainless Steel Observatory Tourbillon Obtaining first prize in the Observatory testing in Geneva in 1931, the present watch is the only known stainless steel tourbillon in private hands. Only one other example of a stainless steel tourbillon is known and is on display at the Patek Philippe museum. Exceptional quality, this tourbillon is further enhanced by the additional gold case, dial and hands which is prominently illustrated in Patek Philippe Stainless Steel Watches by the famed John Goldberger. Further distinguishing this incredible horological work of art, the watch was sold and cased very soon after testing, a mere four years. The majority of other tourbillon watches were tested, and the movement then remained with the firm for another 20, 30 or even 40 years and cased and sold decades after testing to their most prestigious clients. The sector dial truly finishes this magnificent watch and opens the market not only to collectors of historically important pocket watches but will draw the attention of the most astute wristwatch collectors.
