The new Patek Philippe Calatrava Ref. 5227 presented at Baselworld 2013

Equipped with the self-winding caliber 324 SC this new Calatrava Ref. 5227 is definitely a must-have-watch. Please discover more details of this particular watch here …

For decades, the Calatrava – the prototype of the classic round wristwatch, including its Officer’s-style variations with dust covers over the case back – has ranked among the most iconic creations of Patek Philippe. Uniting the key characteristics of this watch family, the new Calatrava Ref. 5227 now features a display back protected with a separate dust cover. The special twist: The entire hinge is on the inside of the cover, making it invisible even to the connoisseur.

The classic round 39-mm case of the Calatrava Ref. 5227, a typical representative of its family with a concave bezel, gently curved lugs, and slender silhouette, is a fine example. But the fact that a 9.24-mm thin watch can have a sapphire-crystal case back plus a hinged dust cover reflects extreme craftsmanship and ingenuity. The small lip that allows the dust cover to be opened can hardly be discerned. However, the hinge with which it is attached to the case remains invisible while the watch is on the wrist. It can only be seen close up when the cover is open, be it to read an engraved dedication or to admire the unique artisanal finishes of the self-winding manufacture movement … the self-winding caliber 324 SC, widely admired in the world of horology.

Its large four-arm Gyromax balance with a Spiromax balance spring made of Silinvar beats at a frequency of 28,800 semi-oscillations per hour (4 Hz) to assure the rate accuracy specified by the Patek Philippe Seal, within the narrow tolerance range of -3 to +2 seconds per day. And like all movements crafted at the workshops in Geneva, it epitomizes perfection in finissage, which even today is largely performed by hand: from round chamfered and polished bridge edges to Geneva striping, from gold-filled engravings to circular graining and the Calatrava cross that adorns the winding rotor. It is made of solid 21K gold to extract as much winding energy as possible from even the slightest motions of the wrist.

Yet again, 81 years after the debut of the Calatrava, Patek Philippe reasserts the timeless quality of this legendary watch collection as well as the creativity of the manufacture in leveraging its traditions and heritage. It is available in 18K yellow, white, or rose (5N) gold and worn on a hand-stitched alligator strap with large square scales and a matching gold prong buckle. The strap is shiny black for the white-gold model, shiny chocolate brown for the yellow-gold version, and shiny dark brown for the model in rose.
