The reference 5059 combines two distinct traditions in one case: the perpetual calendar complication that automatically tracks short months and leap years without adjustment, and an "Officer's" style hinged case back, a design borrowed from military pocket watches that springs open at a touch to reveal the movement rather than requiring tools. Rather than a conventional date window, the date is shown by a hand sweeping a 240-degree retrograde arc, snapping back to the start at the close of each month.
This example is cased in 18k rose gold, with a white enamel dial, Roman numerals, and day, month, and moonphase displays arranged around the retrograde date scale. The caliber 315/136 carries the Geneva Seal, finished with Côtes de Genève visible through the hinged sapphire back. Fitted to a brown alligator strap with rose gold Calatrava Cross deployant clasp, it represents one of Patek's more historically minded takes on the perpetual calendar.
The watch is delivered with all items shown in the photographs.
