Production of these models began with the Cal. 27-70 Q bearing the serial number 875 000. This calibre was produced until 2009. Initially, this new chronograph model with perpetual calendar – the successor to Ref. 2499 / 100 – was marketed under two separate references: • Ref. 3970, supplied with a snap-on solid case-back. • Ref. 3971, supplied with a snap-on glass case-back featuring a sapphire-crystal for viewing the watch movement. Production of 100 watches is planned for each of these references. Production is scheduled to take around two years. The manufacture then upgraded these two models by fitting them with screwed case-backs, giving the watch a degree of water-resistance. It should also be noted that the inside of the subsidiary dial at 3 o’clock, which indicates day and night time, is now two-tone. The reference numbers for these models were soon standardised into a single number, reference 3970. The watch is offered to customers with one or two screwed case-backs: the first of these is the screwed solid case-back, while the second, which is not compulsory, is the screwed sapphire-crystal case-back. With the events surrounding the 150th anniversary of the manufacture in 1989, Patek Philippe experienced considerable growth. Annual production rose from around 9 000 watches to 14 000 orders. Among these, the reference 3970 was highly prized by enthusiasts. Around 1 000 watches were produced until the model was discontinued around 2004. Today, specialists categorise this model as follows: Reference 3970 • 1st series, with snap-on solid case-back (+/- 100 watches produced in 1986-1987) • 2nd series, with screwed solid case-back (watches produced in 1988-1989) • 3rd series, with screwed solid case-back and possibly a screwed glass case-back with sapphire-crystal (watches produced from the end of 1989) Reference 3971 • 1st series, with snap-on glass case-back with sapphire-crystal (+/- 100 watches produced in 1986-1987) • 2nd series, with screwed glass case-back with sapphire crystal and possibly a screwed solid case-back (watches produced in 1988-1989) As a result, very few watches bear the reference 3971, and those with a solid case-back bearing this reference are extremely rare. -- Bibliography • Huber, Martin, & Banbery, Alan, Patek Philippe Wristwatches, 1998, p. 305. • Nael, Ali, Patek Philippe, My Dream Collection, 2021, pp. 376-377. Patek Philippe, Master of all Horological Complication Patek Philippe is a prestigious Swiss watch manufacturer, renowned for its luxury watches and exceptional craftsmanship. Founded in 1839 in Geneva by Antoine Norbert de Patek (1812-1877) and François Czapek (1811-after 1869), the company quickly established its reputation as a manufacturer of superior watches. In 1844, following the National Exhibition of French Industrial Products in Paris, Antoine Norbert de Patek met Jean-Adrien Philippe (1814-1894), a young French watchmaker. In 1845, after Czapek’s departure, the two men concluded a commercial agreement and introduced numerous innovations in the field of watchmaking, notably a keyless-winding and time-setting system for which Philippe received a Bronze medal. In 1851, the company was renamed “Patek, Philippe & Cie – Fabricants à Genève”, and over the decades became synonymous with exclusivity, precision and technical perfection as evidenced by the wristwatch made for the countess Hungarian Koscowicz (1868), patents for a precision regulator (1881), a perpetual calendar mechanism (1889), a double chronograph (1902) and all the brand’s creations, whether pocket watches or watches. bracelets with horological complications. From the early 1900s until 1927, Patek Philippe introduced a unique business model. The house’s main distributor based in Rio de Janeiro in Brazil, “Gondolo & Labouriau” sold more than a third of the production at the time thanks to a cleverly orchestrated sales system. These timepieces, known as “Chronometro Gondolo”, are collector’s items famous both for their very high technical quality and for their unique history. The watches were sold at the time, exclusively to members of a very select clubs called the “Gondolo Gang” which have 180 members. Being part of these collector’s clubs was, at the beginning of the 20th century, a distinctive sign of success in Brazilian society. According to an ingenious raffle system, each member of the club agrees to buy a watch for the amount of 790 Swiss francs divided into 79 weekly instalments of 10 francs. During these 79 weeks of repayment, a weekly draw is organized where the winner is released from the balance of his debt. The first winner pays 10 francs for their watch, the second 20 francs, etc. The earlier you buy your watch, the cheaper it costs, provided you win this lottery. Echoing this episode in its history, the “Gondolo” collection was reinterpreted in 1993 with shaped watches. In 1932, Patek Philippe became a family business when the Stern family, already involved in the production of dials for the brand, bought the company. It is also the year of the launch of a model that will become the brand’s flagship collection: the “Calatrava”. Even today, it contributes to the success and reputation of the company. Among the emblematic models of Patek Philippe, we can also mention the “Ellipse” (1968) with its elliptical-shaped case, at the crossroads of the circle and the rectangle which is inspired by the “golden ratio”; the “Nautilus” (1976), a sporty and luxurious watch whose case is inspired by a porthole; or watches for women, such as the “Twenty-4” collection (1999), which combines feminine elegance with horological precision. Since its creation, the brand has been driven by a spirit of innovation. In 1989, Patek Philippe released a very complex model to celebrate its 150th anniversary. Named “Calibre 89”, the watch is equipped with 33 horological complications and its calibre is made up of 1 728 parts. Eleven years later, in order to celebrate the second millennium, the brand released the “Star Calibre 2000” model, a double-sided pocket watch with 21 horological complications. Finally, the year 2002 saw the launch of the “Sky Moon Tourbillon” model, the most complicated double-sided wristwatch ever produced by the house. Benchmark precision instruments, Patek Philippe watches are also recognized by collectors for being objects of art whose beauty reflects perfection. For many years, Patek Philippe has strived to preserve all the high craftsmanship professions linked for more than four centuries to the decoration of timepieces. This is how exceptional contemporary creations come into being – pocket watches, wristwatches, or clocks –, most often unique pieces, which highlight all these skills that are threatened with disappearance. This transmission value is essential for the brand. Patek Philippe can be proud of having filed more than 70 patents since its creation, notably for a Gyromax balance-wheel (1949), mechanical watches with time zones (1959), a mechanical movement with peripheral rotor (1964), an indicator mechanism of the date of Easter (1985), an annual calendar (1996) or even an astronomical representation mechanism (2000). These technical innovations have largely contributed to advancing the horological industry while contributing to the brand’s reputation for excellence. Today, Patek Philippe is a watch brand that continues to produce superior quality watches that are admired by watch enthusiasts around the world. -- Key Dates • 1839: foundation of “Patek, Czapek & Cie2 by Antoine Norbert de Patek and François Czapek in Geneva. • 1845: following the departure of Czapek, the company becomes “Patek & Cie”.
