Patek Philippe Golden Ellipse

The Golden Ratio Behind the Case

In 1968 Patek Philippe did something the industry was not doing: it built a watch around a number. The case of the Golden Ellipse follows the golden section — the ratio of roughly 1 to 1.6181 that ancient Greek mathematicians identified and that has governed the proportions of Western art and architecture ever since. The result is neither round nor rectangular. It is an ellipse whose width and height sit in the one relationship the eye reads as balanced without being able to say why. The first models, references 3648 and 3646, arrived with a 27 mm case and a hand-wound movement. The 3648 hid its lugs entirely, so the strap appeared to grow out of the case. Blue gold dials — an alloy given its color by heat treatment rather than paint — became the collection's signature and remain among the most sought-after vintage Patek dials today. Nearly six decades on, the geometry has not been redrawn. Patek Philippe has changed the metals, the dials and the movement inside, but the outline is the one it settled on in 1968.

Caliber 240: The Movement That Makes It Thin

The Golden Ellipse could not be this slim on a conventional automatic movement. In 1977 Patek Philippe introduced caliber 240, and every watch in the collection has used it since.

How the Four References Differ in Practice

On paper the current lineup shares one case and one movement. On the wrist they are four quite different watches. The 5738R-001 in rose gold on black alligator is the reference point — the most straightforward expression of the design, and the most accessible way into the collection. The 5738P-001 swaps rose gold for platinum and black for a sunburst blue dial; introduced in 2008 for the collection's 40th anniversary, it is the heaviest of the four and the one that reads most formally under a cuff. The 5738/1R-001 is the outlier. It was the first 5738 fitted with a chain-style bracelet: 363 individual elements in rose gold, more than 300 of them mounted by hand, with a clasp offering three adjustment positions. A Golden Ellipse on gold is a different proposition to one on leather, and the price reflects the labour rather than the metal alone. The 5738/51G-001 belongs to Patek Philippe's Rare Handcrafts. Its 18K gold dial plate is hollowed out to receive black Grand Feu champlevé enamel, and the gold left standing is then hand-engraved with floral motifs. Two traditional crafts, one dial. The case runs slightly thicker at 6.58 mm and — unlike its siblings, which are rated to 30 meters — it is protected against dust and humidity only.

Golden Ellipse Sizes: Jumbo and Medium

The 5738 case at 34.5 x 39.5 mm is what collectors call the Jumbo, though by modern standards it wears as a compact dress watch. The smaller 3738 case, at 31.1 x 35.6 mm, is the medium format that carried the collection through the 1990s and 2000s and still turns up regularly on the pre-owned market. Both are unisex by design; the medium is the more common choice for a smaller wrist. If a 34.5 mm dress watch is where you want to be, the Calatrava and Gondolo collections cover similar ground in round and rectangular cases.

Patek Philippe Golden Ellipse Price

Within the current collection, price tracks metal and handwork rather than complication — there is no complication to pay for. The spread runs from the rose gold 5738R-001 at the entry point to the enamelled 5738/51G-001 at better than double it, with the platinum 5738P-001 and the bracelet 5738/1R-001 in between. On the secondary market the bracelet reference is the one that most often trades above its retail figure, because a gold chain-style bracelet is slow to produce and Patek Philippe makes few of them.
