1947 - Patek Philippe 1461

這張印有「& Co.」的格式保單是非常稀有的收藏，保單左下角的草寫清楚標示：「Sold 16th June 1947」。 在百達翡麗的歷史中，1947 年至 1948 年正是公司從「合夥制」（& Co.）轉向「股份制」（SA，Société Anonyme）的轉折點。雖然內部決策已在 1947 年逐步推動更名，但舊有的實體保單、信箋以及行政用印，並不會在決議通過的那一天立刻作廢，通常會延續使用直到庫存消耗完畢。

THIS CERTIFICATE OF ORIGIN PRINTED WITH "& CO." IS AN EXTREMELY RARE COLLECTIBLE. THE CURSIVE SCRIPT IN THE LOWER-LEFT CORNER CLEARLY INDICATES: "SOLD 16TH JUNE 1947." IN THE HISTORY OF PATEK PHILIPPE, THE YEARS 1947 TO 1948 MARKED THE CRITICAL TRANSITION FROM A PARTNERSHIP (& CO.) TO A JOINT-STOCK COMPANY (SA, SOCIÉTÉ ANONYME). ALTHOUGH THE INTERNAL DECISION TO CHANGE THE NAME WAS GRADUALLY IMPLEMENTED STARTING IN 1947, EXISTING PHYSICAL DOCUMENTS—INCLUDING CERTIFICATES, STATIONERY, AND ADMINISTRATIVE SEALS—WERE NOT IMMEDIATELY RENDERED VOID. INSTEAD, THEY CONTINUED TO BE UTILIZED UNTIL THE EXISTING STOCK WAS EXHAUSTED.
