Overview
The Golden Ellipse as a canvas
The Patek Philippe Rare Handcrafts Etna, reference 5738/50R-010, a Golden Ellipse in rose gold with a dial in cloisonné and paillonné enamel and miniature painting showing the volcano in eruption, on a shiny dark brown alligator strap. Self-winding calibre 240, hours and minutes only; 34.5 × 39.5 mm, 6.58 mm high.
The rose gold execution 5738/50R-010 shows Mount Etna in Sicily, which Patek Philippe describes as the most active volcano in Europe, in eruption under a starry sky. The outline of the massif took about 9.4 cm of gold wire (~0.05 g); the enameller worked from transparent and opaque enamels in 6 colours, set gold leaf beneath translucent enamel — the paillonné technique — to make the river of lava glow, and added miniature painting on enamel in 5 colours for the burning slopes and the ash cloud. Each dial took 10 firings at 770°C. The solid case back carries a stylised engraving of the volcano and its name. Patek Philippe presents it as a limited edition of fifteen watches, on a shiny dark brown alligator strap with a rose gold prong buckle.
The reference 5738/50 is the Golden Ellipse of Patek Philippe's Rare Handcrafts collection: the elliptical case whose proportions the brand traces to the ancient golden section, here 34.5 × 39.5 mm and 6.58 mm high, with a solid case back. The dial carries only hours and minutes, read from cheveu-style hands stamped in the case metal.
The movement is the self-winding calibre 240, which Patek Philippe lists as ultra-thin: 27.5 mm across and 2.53 mm high, with 152 parts and 27 jewels, wound by a 22K gold minirotor set off-centre in the movement rather than a full rotor turning above it. It runs at 21,600 semi-oscillations an hour on a Gyromax® balance with a Spiromax® balance spring, has a power reserve of at least 48 hours and carries the Patek Philippe Seal. A calibre 2.53 mm high is what lets the case close at 6.58 mm over a dial built up in fired enamel or veneer. Patek Philippe describes the case as humidity- and dust-protected only, not water-resistant.
For collectors
Across the family the case and the movement do not change, so the executions are compared by the dial: Patek Philippe gives each one its own figures — the length and weight of gold wire in a cloisonné dial, the number of enamel colours, the firings and their temperature, or the count of veneer parts and wood species in a marquetry dial — and each is a limited series whose size the brand states. The solid case back is part of the design; the calibre 240 is not on view.
