Patek Philippe Calatrava Solid 18K Yellow Gold 33mm Watch (Ref. 3919/20) W/Extract from the Archives - This handsome, investment quality timepiece was made by one the most prestigious luxury watchmakers in the industry, Patek Philippe. This watch made its debut as part of the Calatrava line, and features: 33mm solid 18k yellow gold case with coveted hobnail bezel, porcelain white dial with applied sword-shaped hands and painted black Roman Numeral markers, small seconds sub-dial at 6 o'clock, scratch resistant sapphire crystal, mechanical manual-winding movement, and solid 18k yellow gold bracelet. Patek Phillippe watches are some of the most sought after in the world, as it is said that fewer than 1 million Patek Philippe watches have been made since 1839. The Patek production is so detailed that it takes approximately nine months to make its most basic watches, and over two years to produce some of the more complicated pieces. This watch has excellent investment potential, as Patek Philippe resale value is above that of all other makers, vintage or modern. The watch measures 7.25" in length, and will be accompanied by the Extract from the Archives (the paperwork will be delayed as it will be ordered in the winning bidder's name). It is in excellent condition, and is working. Ref. #: 3919/20.
