Patek Philippe Calatrava 3417

Wow!! When was the last time you saw one of these pieces come up for sale. 93% Near Mint condition Patek Philippe Ref 3417. Calibre 27 AM 400 amagnetic; manual winding; date of mfg: 1964; 35mm Stainless Steel case with screwdown caseback. This particular piece was purchased by me from a reputable source.

All Patek service paperwork will be provided, along with the Extract from the Archives. There is absolutely no risk here. You get to own/wear a vintage, rare timepiece that has been completely serviced and inspected by Patek Philippe. Watch will come with 90% shiny black alligator hand-made strap 18/14 120/75 from John Allen Woodward, with ss Patek tang buckle. Plain and simple - the movement is what makes this piece. The Ref 3417 was developed to withstand strong magnetic fields in laboratory settings. Along with Rolex, Omega, IWC, and Jaeger-LeCoultre, the Patek Ref 3417 were true scientist tool timepieces. "The reference 3417 is an anomaly of sorts for Patek. This anti-magnetic timepiece resembles a simple dress watch, of which Patek has made thousands in precious metals, but this one is cased in stainless steel. The watch itself was launched with an existing, manually wound caliber 12-400 in 1958, but by 1960, Patek had conceived what many believe to be the greatest movement ever made, the 27AM-400. This manually wound movement was shielded from electro- magnetic influence, due to an intermediary steel case back and an escapement made of nonmagnetic materials. Because of this, the reference 3417, with a stainless steel case more desirable and valuable than a Patek in a precious metal, and an elegant and innovative 27AM- 400 caliber, is one of the most interesting and sought- after watches to astute collectors today: It's an example of Patek's rare forays into the purpose-built tool watch category". - "Hodinkee" Asking $23,500, includes USPS Registered Mail with insurance.
