This is an antique Patek Philippe EXTRA 18K gold open face pocket watch dating to circa 1911. The watch is accompanied by the original certificate issued from the Government Observatory in Geneva Switzerland. The watch was tested over a period of 44 days and received a First Class grade. Also included is a letter from the Raymond C. Yard, Inc., jewelers in New York City. The letter appears to identify the watch as a Patek Philippe Tourbillon model, but we do not believe the identification of the particular model to be accurate. The back of the case is monogrammed "ASM". The serial number is 162710. The watch is accompanied by an extract from the Patek Philippe archives. Length: 68mm. Diameter: 49.5mm. Weight: 100.0g.

Missing the crystal. The balance staff is broken, but the balance wheel and spring are good.
