Catalogue Essay
Introduced in 1998, the reference 5059 is a companion timepiece to the reference 5050 released in 1993, and was the brand’s first serially produced perpetual calendar watch with retrograde date. Both models featured the sophisticated, self-winding caliber 315 S-QR with a striking 21K gold rotor, based on the caliber 315 SC featuring center seconds. A robust and state-of-the-art in-house movement, it features an intriguing retrograding date complication as part of its perpetual calendar function. At the end of each month, the date hand automatically flies back to its original starting point – a very difficult function to reliably implement in watchmaking.
The pink gold case of the present watch is beautifully designed, curvaceous and gentle, based on the iconic officer style case with hinged caseback and elongated lugs and screwed pins.

It is the stunning brown dial with special luminous monogram dial with Breguet numerals that draws awe from collectors. The present reference 5059 is a possibly unique example and the only one known to feature a lovely brown, luminous dial with Breguet numerals. Another rare and important detail on the dial is the subtle monogram, ‘MSO’, presented at 6 o’clock. To be granted one’s monogram to be printed on the dial, the collector’s importance to the brand was truly significant.

Patek Philippe’s perpetual calendar wristwatches are cherished by collectors both for their innovative movements and timeless designs. The present, possibly unique example is in outstanding overall condition, and complete with its Certificate of Origin and presentation box. Elegant and versatile, this exceptional and rare perpetual calendar is certain to delight.
