Phillips in Association with Bacs & Russo Announces a Full Set of Four Philippe Dufour Watches to be Offered in The Geneva Watch Auction: XIV in November 2021

A Phillips and Bacs & Russo association

Phillips in Association with Bacs & Russo has recently announced four major Philippe Dufour creations that will be offered in its upcoming sale this Fall: The Geneva Watch Auction: XIV. All fresh to the auction market, the watches are coming from a private collector who over the years has assembled these masterpieces. The group includes the Grande & Petite Sonnerie pocket watch Number 1 in yellow gold, the Grande & Petite Sonnerie wristwatch number 1 in yellow gold, the Duality in pink gold and the Simplicity (37mm) in platinum.

Rarely has a watchmaker singlehandedly so well represented a horological genre that has gone from being reserved for the cognoscenti to a category that is boxing in the heavyweight league as Philippe Dufour. Dufour exemplifies what we have collectively come to imagine as the typical Swiss watchmaker: a pipe-smoking figure working in a small workshop in the Swiss mountains making watches by hand of incomparable beauty and quality, infused with passion and love. Dufour is all the above and much more. An extremely talented and passionate watchmaker, he is an ardent defender of traditional watchmaking that he considers a dying art that needs to be transmitted. A true living legend, his watches are considered masterpieces that collectors treasure, making them extremely difficult to obtain.

 “To us and a huge community around the world, Philippe Dufour is the horological equivalent of Michelangelo, the importance of his work cannot be overstated. This “set” of four Philippe Dufour timepieces has been an epiphanous moment for us. Offering his four creations – the Grande & Petite Sonnerie pocket watch, Grande & Petite Sonnerie wristwatch, Duality and Simplicity – is truly humbling and mind boggling. Dufour is a living icon and his creations are as coveted as oeuvres by the greatest artists of our time. How awe-striking that we are offering the very first Grande & Petite Sonnerie wristwatch ever made!  We are honored to have been entrusted with this collection from an owner who had the vision and passion to patiently assemble a collection like no other. Dufour’s lifetime output is smaller than paintings by masters such as Modigliani and Mannet and for any Dufour connoisseur, this collection represents the Grand Slam of Dufour collecting.”

An independent watchmaker since the late 1970s, Dufour restored antique and vintage timepieces, which led him ten years later to develop a very small series of pocket and wrist grande sonnerie watches. These were followed by the Duality, the world’s first wristwatch incorporating a double escapement, and finally the Simplicity, featuring a movement architecture designed to demonstrate hand finish and decoration that modern horology had not yet witnessed. In the span of over 30 years since he created his eponymous brand, Dufour created only these four models under his name.

A Grande Sonnerie is a timepiece that automatically chimes the hours on every hour and hours and quarters on every quarter, and when on petite sonnerie mode the watch will only chime the passing of the quarters. Phillipe Dufour began his work on the grande sonnerie with a series of five pocket watches made for a large brand in the early 1980s. The fact that the brand never acknowledged his work led him to create his own Grand & Petite Sonnerie pocket watch in the late 1980s. The present example is number 1 and the only Dufour Grande & Petite pocket watch made that bears his name on the dial.

From 1989 to 1992, Dufour set out on the difficult task of miniaturizing his sonnerie movement to wristwatch size and the result was the present Grande & Petite Sonnerie wristwatch number 1, a world premiere that makes the present example offered at auction the world’s very first Grande & Petite Sonnerie wristwatch. This version was produced in only five examples with white enamel dials, respectively 2 cased in white gold, one in yellow and one pink gold, as well as one in platinum.

Estimate CHF1million-2 million / US$1,090,000 -2,180,000 / HK$ 8,461,000-16,922,664

Dufour’s inspiration for the Duality came from a few school watches from the Vallée de Joux watchmaking school of the 1930s – the same school that Dufour graduated from. These pocket watches had a single gear train delivering power to two balance wheels through a differential. Once again, like with his sonnerie wristwatch, Dufour set out on the task of shrinking this mechanism to wristwatch size.

In 1996, Dufour introduced his iconic Duality, the world’s first wristwatch incorporating a double escapement. Featuring two independent balance wheels compensated with a central differential gear, the mechanism improves accuracy while also countering the effects of gravity. He initially planned to produce 25 examples, however, only nine were made including an example with movement number ‘00’ (sold at Phillips New York in 2017 for close to $1 million), making the present example bearing number 8 the last one made. It is one of three pink gold examples ever produced.

Estimate CHF 800,000-1.6 million US$872,152-1,744,520 / HK$6,768,000 – 13,540,596

Simplicity (37mm) platinum number 57

After having proven his undeniable talent and expertise in creating ultra-complicated mechanisms, Dufour set out in 2000 on the challenging task to create a simple three hand watch with a movement architecture designed to demonstrate hand finish and decoration that modern horology had not yet witnessed. The gentle flow of the bridges’ curves, the bold and alluring inward and outward angles, the hand applied Geneva waves and red rubies all provide a seductive visual harmony. The facts that the decoration and assembly are done by hand explains the fact that less than a dozen Simplicities left Dufour’s workshops in the Vallée de Joux per year. The present watch bearing movement number 57 is one of the earlier models that the master produced.

Estimate CHF 250,000-500,000 / US$272,581 – 545,176 / HK$2,115,743 – 4,231,326
