Armand Schwob & Frère AS & F. is a Swiss company that produces watches and is also known as Draper Watch Co. and AS & F. Macolin Watch Co.
Armand Schwob & Frère, located at 14 Avenue Leopold Robert in La Chaux-de-Fonds, was established on November 1, 1881. The company registered on January 27, 1883, as a manufacturer of metal watches in La Chaux-de-Fonds. The owners, Armand Schwob and Abrabam Schwob, originally from Basel but residing in Paris, also operated a watch and jewellery store at 19 Boulevard Bonne-Nouvelle in Paris.

In 1883, Armand Schwob & Frère participated in the Amsterdam exhibition, showcasing watches under the AS & F. brand and the name Patek Cie. However, an unfortunate incident occurred during the Antwerp World Exhibition on July 9, 1885. The jury, accompanied by Adrien Philippe, discovered a pocket watch with the serial number 26291 and the signature Patek & Cie in the window of the Armand Schwob & Frère establishment in Geneva, causing a scandal. In 1886, another watch bearing the initials AS & F. was brought to Patek Philippe for repair. The final piece of evidence emerged in 1890 when Georges Roulet testified that he had engraved the name Pateck & Cie, Geneva, upon the formal written request of the Armand Schwob & Frère company.

The Schwob company faced legal action in 1890 for infringing on naming rights and was found guilty. As a result, they were fined 15,000 francs and prohibited from using the names Pateck or Patek. During the trial, a witness testified that Schwob had used Patek Cie for their watches since 1833. The conviction was published in five newspapers selected by Patek Philippe & Cie, and all legal costs were added. In 1892, the company in Paris and La Chaux-de-Fonds was declared bankrupt.
