Flyback Chronograph with Annual Calendar

n 2014, Patek Philippe‘s Ref. 5960/1A Annual Calendar Chronograph in stainless steel became one of the manufacture’s rare classically elegant watches that combine a complicated movement with a stainless steel case. When the model was first was launched in 2006, the Patek Philippe Annual Calendar Chronograph in platinum was the manufacture’s first self-winding chronograph, featuring a prominent monocounter and three large calendar apertures. The model quickly established itself as one of the most coveted timepieces of the Patek Philippe portfolio.

Patek Philippe‘s stainless steel watches have always ranked (as CITIZEN ECO DRIVE RADIO CONTROLLED ) among the most desirable timepieces because they were crafted only in small numbers. They were not regularly produced until 1976, when the manufacture introduced the casually elegant Nautilus line. Its memorable slogan: “One of the world’s most expensive watches is made of steel.” Twenty years later, the attractively stylish Aquanaut was also endowed with a stainless steel case. Since 2014, the Ref. 5960/1A is another one of these seductive exceptions:

Ref. 5960/1A-001 in stainless steel – the letter “A” in the model designation 5960/1A stands for acier (steel in French)

Dial: silvery opaline, blackened gold applied hour markers. Steel bracelet with folding clasp. Sapphire-crystal case back. Water resistant to 30 m. Case diameter: 40.5 mm. Height: 13.5 mm.

The new 40.5 mm stainless steel case melds classic elegance with masculine sportiness. It emphasizes the active and dynamic nature of the chronograph and underscores its function as a timekeeping instrument. Nonetheless, the new Ref. 5960/1A has a decidedly elegant nimbus attributable to the balanced, gently rounded case contours and the superb finishing touches that reflect the competence of Patek Philippe‘s casemaking ateliers. The artisans are required to accrue several years of experience before being entrusted with the finissage of the manufacture’s cases. Because of its hardness, stainless steel challenges the skills of the case specialists and imposes special requirements on their tools. It takes much longer than a gold case would to polish a steel case with consecutively finer abrasives until it reflects light with an immaculate sheen.

Technical elegance also characterizes the new silvery-gray dial with its striking red accents, bright-dark contrasts, and the dynamic, performance-oriented looks of its explicitly three-dimensional architecture. An uncommon feature in a Patek Philippewatch: the red “1” in the date aperture, which kicks off each month with a colorful stimulus while the dates from the 2nd to the 31st days are displayed black on white. It is a genuine premiere for Patek Philippe, as is the combination of an Annual Calendar chronograph with a steel case and the stainless steel “drop” links bracelet that underscores the functionality of the Ref. 5960 as a measuring instrument.

In 2017, Patek Philippe introduced a version with white-gold case and blue dial, calf leather strap with contrast stitching, and guilloched pushers, paying tribute to some of Patek Philippe “vintage” models. Sapphire-crystal case back. Water resistant to 30 m. Case diameter: 40.5 mm. Height: 13.5 mm.

Also in 2017, Patek Philippe introduced a second version with stainless steel case, bracelet and blue black dial. Sapphire-crystal case back. Water resistant to 30 m. Case diameter: 40.5 mm. Height: 13.5 mm.
