Rolandc's 2019 post captures the excitement and deliberation of acquiring a Patek Philippe 3940J, a perpetual calendar reference highly esteemed by collectors. His detailed inquiry into the watch's condition and potential servicing costs provides a valuable real-world case study for anyone considering a pre-owned Patek Philippe, highlighting the importance of due diligence and expert consultation.
The Patek Philippe Reference 3940 is a perpetual calendar wristwatch that was introduced in 1985, succeeding the Reference 3450. It is notable for its relatively slim profile and the integration of a perpetual calendar complication in a refined case. This reference became a cornerstone of Patek Philippe's complicated watch offerings for nearly two decades, establishing a design language for subsequent perpetual calendar models. It represents a significant period in the brand's modern history of complicated timepieces.
The watch features a 36mm case, typically crafted from yellow gold, rose gold, white gold, or platinum. It houses the self-winding Caliber 240 Q movement, which is known for its micro-rotor construction, contributing to the movement's thinness and allowing for a slimmer case profile. The movement provides a power reserve of approximately 48 hours. The dial is protected by a sapphire crystal, often accompanied by an interchangeable solid case back and a sapphire display back.
Reference 3940 is highly regarded by collectors for its classic proportions and the enduring appeal of its perpetual calendar display, which includes day, date, month, leap year cycle, and moon phases. It was produced in several series, with subtle variations in dial layout and typography, making early series examples particularly sought after. The reference is considered a benchmark for perpetual calendar watches and remains a significant piece for those appreciating traditional horological complications.
Patek could probably make it look at good a new. Interesting proposition.
On the 2 sub dials, the one on the left the top hand seems corroded, probably because the 2 hands are made of different metals. The one on the right will eventually become corroded too, not sure if this is a common problem with this series 3. The price is quite attractive for such a beautiful watch, very well balanced.
Have been wearing one extensively for 10 years. Patek Philippe made thousands of these watches for a couple of decades. If you can get into this piece at a price that makes you comfortable,then do it. Wear it , enjoy it and revel in the excellence that is the 3940. If you want to spend the money down the line, Patek can pretty-well return that watch to nearly 100%. It will cost thousands of dollars and take half a year or ( very likely) more. Ultimately you will get what you paid for. My beloved
I am going to check with Patek on the cost for the replacement for the corroded dial hands. Use a loupe to check earlier, the corrosion only limited to the dial hands. The solid case back is in great condition, sticker still in place. After I get a quote from Patek, will do a final negotiation with the shop.
But why not? Ask how much it will cost for a full service at Patek before taking any decision. Best, Nicolas
but that rust spot(if it is really that) between 6-12 a bit worrisome.
