Upon close observation one can immediately notice the unusual high quality finish of this watch school watch by the double Geneva hallmark stamped on the movement. This combined with the fact that the waterproof case is made by Freres Borgel known to supply their waterproof cases to Patek Philippe. The caliber appears to be from the Patek 565 reference known as 12-120. The dial is stamped by Stern on the reverse (881 3). As it was often the case major watch manufacturers such as Rolex and Patek Philippe supplied some cases and movements to provide to the Geneva watch making schools for their final project. This watch made by Daniel Gras was most likely made using the same case and movement as the famous reference 565 by Patek Philippe. It is the third time Antiquorum has sold a Geneva watch school watch with a Borgel case and a Patek Philippe ebauche (see the Art of Patek Philippe, November 14, 1999, lot 586 and Exceptional Collectors Timepiece, May 15, 2005, lot 165)
