Superb Patek Philippe Ellipse d'Or “Jumbo” Ref. 3738 Sigma – Full Set

In 1968, Patek Philippe unveiled the Golden Ellipse, inspired by the golden ratio – the first new collection in its own right since the Calatrava of 1932.
The reference 3738/100 “Jumbo,” widely regarded as the most desirable Ellipse to date, houses the famous 22-carat gold micro-rotor calibre 240, an ultra-thin automatic movement only 2.53 mm thick.
This 18-carat yellow gold example is preserved in excellent overall condition. Its sunburst blue “Sigma” dial displays a deep and even radiance, enhanced by solid gold baton hour markers and hands. The hallmarks on the case are exceptionally clear. The original black crocodile strap is complemented by the yellow gold Ellipse pin buckle. The movement, fully serviced, runs perfectly.
We are pleased to present this superb Ellipse, still accompanied by its original “Full Set” including its Patek Philippe Certificate indicating an initial sale on July 11, 1991, in Nuremberg, Germany, its octagonal burgundy presentation box, carrying pouch, label, document holder, and various accessories. A complete set of this caliber for a 3738 has become extremely rare – an exceptional opportunity for the discerning collector.

In 1968, Patek Philippe unveiled the Golden Ellipse, its first new collection since the Calatrava of 1932. The design, inspired by the “golden ratio” – the proportion 1/1.6181 that Greek mathematicians considered the very expression of harmony – broke radically with the watchmaking conventions of the time. Neither round nor rectangular, the watch's elliptical shape immediately established it as an icon of understated luxury, positioning Patek Philippe at the forefront of watch design on the cusp of the quartz crisis.

The first references (3546 and 3548) were hand-wound. In 1977, the introduction of the Calibre 240 – an ultra-thin automatic movement with an off-center micro-rotor in 22-carat gold, developed under the direction of Gérard Berret – marked a decisive turning point for the collection. At just 2.53 mm thick, the Cal. 240 beats at 21,600 vibrations per hour, has a 48-hour power reserve, and incorporates a Gyromax balance. It was precisely the reference 3738, known as the “Jumbo,” that was chosen to house this new caliber – a combination that, nearly fifty years later, remains unchanged in the collection with the current reference 5738. The Cal. 240 also serves as the basis for the manufacture's most prestigious complications: perpetual calendar, world time, and celestial chart.

Reference 3738/100 is now widely considered the most desirable in the Ellipse collection. Its proportions of 31 x 35.5 mm – generous for its time, yet perfectly balanced – combine a strong presence on the wrist with exceptional finesse thanks to the Cal. 240 movement. The 18-carat yellow gold case, with its mirror-polished bezel and solid snap-on case back with a vertical satin/brushed finish, exemplifies the mastery of goldwork so dear to the Geneva manufacture.

The example we are pleased to offer is preserved in excellent overall condition and is distinguished by the remarkable completeness of its original components. The sunburst blue “Sigma” dial – the two σ symbols framing the “SWISS” inscription at 6 o'clock certifying, according to the standards of the Swiss APRIOR (Association for the Industrial Promotion of Gold), that the hour markers and hands are solid gold – radiates a deep and even glow from the center, accentuated by applied gold baton hour markers and exquisitely slender hands. The hallmarks on the case side are exceptionally crisp. The original Patek Philippe black crocodile leather strap is paired with the yellow gold Ellipse pin buckle, which echoes the lines of the case and completes the overall harmony. The self-winding mechanical movement has been fully serviced and is in perfect working order.

The watch comes with its Patek Philippe Certificate of Origin, attesting to its initial sale on July 11, 1991, at Der Juwelier Lunk in Nuremberg, Germany; its original burgundy presentation box; its rectangular travel pouch; its original label bearing the case and movement numbers; its burgundy document holder; and various period documents and accessories. Such a complete set for a 3738 has become extremely rare – the vast majority of examples on the market are presented without papers, and even rarer are those with all the original accessories.

For the discerning Patek Philippe collector, this Ellipse d'Or/Golden Ellipse reference 3738/100 “Full Set” represents a rare opportunity: the quintessence of design according to the golden ratio, the prestige of the Cal. 240 with micro-rotor, a remarkably preserved blue Sigma dial, and all the original accessories together.
