Found: The Patek Philippe Observatory Tourbillon Worn As The Personal Watch Of Retired President Philippe Stern

The development has a long history. It was completed in 1945, and was planned by the expert watchmaker André Bornand. Bornand (1892-1967) was an educator at the Geneva School of Watchmaking and quite possibly the most renowned tourbillon experts of the twentieth century. 

The development – no. 861,115 – was uniquely adapted to the Geneva Observatory preliminaries by André Zibach (who changed the development on seven separate events, somewhere in the range of 1948 and 1959) and again in 1963, by Max Studer (per the Patek Philippe Museum). The explanation I’m referencing these names is on the grounds that these folks were the geniuses of the Swiss watch industry in their time – changing even a customary watch to keep a nearby rate, under the requesting examination of an observatory competition, was very troublesome and changing a tourbillon, considerably more so. The development has a bimetallic Guillaume equilibrium and steel Breguet overcoil (the Guillaume balance was by a long shot the most complex of bimetallic temperature compensating balances; they were utilized by Rolex in its renowned “Kew A” chronometers ) and vibrates at 21,600 vph.

Patek observatory tourbillon wristwatches from the twentieth century were made in exceptionally little numbers, and planning and changing them was a lot of a dark workmanship, yet as the years passed by the company aggregated impressive ability. Above is another such development, likewise planned by André Bornand, and with an abnormal 50 second tourbillon. Development no. 866,503/type 34T was changed by René Mathey for the competitions, and it has various intriguing highlights – like no. 861,115, it has a Guillaume compensating equilibrium and steel Breguet balance spring, yet it additionally has an enclosure made of beryllium bronze, which is amagnetic and furthermore less monstrous than steel, making it ideal for a tourbillon carriage. 

Caliber 34T is a Bornand change of the rectangular Patek type 34S; it has a 57-hour power save. As per the Patek Museum, there were an aggregate of five worked somewhere in the range of 1958 and 1966, and “… all got top of the line chronometry notices and two won the primary prize in their classification in the Geneva Observatory competition.” This specific development was granted a “Announcement de Première Classe” with First Prize notice at Geneva, in 1958. It was not cased until 1983 and is currently in the Patek Philippe Museum.

Mr. Phillipe Stern, privileged leader of Patek Philippe.

Some time in the mid 1980s, the round development you see up top got the attention of Patek President Philippe Stern, and at his solicitation, it was put for a situation for him to wear in 1987, accepting the assignment ref. 3699.

Everyone has their own thoughts of what a definitive wristwatch may be, and obviously, what a definitive Patek Philippe may be. (Actually I have around 10 unique contender for both consistently.) But there is something bracingly unadulterated about ref. 3699. It’s outright in its determined commitment, in origination and development, to something substantially more than some dull thought of extravagance – an outflow of a combination of best in class timekeeping innovation of now is the right time, with a degree of expertise in assembling and adjusting that has become practically wiped out in Switzerland or elsewhere. It may very well be, in case you’re interested by the combination of exactness and high art that marks watchmaking at its most elevated level, quite possibly the most delightful watches ever made.
