The Manufacture is expanding its vast selection of chronographs by unveiling three variations of the 5204, 5905 and 5930 models that illustrate its expertise in the field of complications, particularly in the measurement of short times.

The chronograph has always played a leading role amid the vast repertoire of Patek Philippe complicated watches. Since 2005, the Manufacture has confirmed this mastery by developing a complete range of chronograph movements, with or without additional functions, entirely designed and crafted in its workshops.

The starting point was caliber CHR 27-525 PS, the world’s thinnest split-seconds chronograph movement presented in 2005.

Introduced in 2006, caliber CH 28-520 – the second “in-house’” chronograph movement – features automatic winding, a modern vertical disk-type clutch system, a flyback function, a large single counter at 6 o’clock and a chronograph seconds hand that can be used as a permanent (running) seconds hand. It can be combined with additional complications, as is the case with the two new models: 5905/1A (chronograph and Annual Calendar) and 5930P (chronograph and World Time).

Launched in 2009, caliber CH 29-535 PS – the third exclusive chronograph movement – combines traditional architecture (manual winding, column wheel, toothed-wheel horizontal clutch system) with six patented innovations. In the current collection, it powers a men’s model (Reference 5172) and a ladies’ model (Reference 7150/250). In 2011, this base caliber was interpreted in a Grand Complication version incorporating a perpetual calendar (CH 29-535 PS Q), present on the 5270 and 5271 models. Since 2012, it can also be found on Reference 5204 in a split-seconds chronograph and perpetual calendar version (CHR 29-535 PS Q).

The various Patek Philippe chronograph calibers are offered in the current collection in more than 20 variations – to which three new, resolutely contemporary interpretations have now been added.

Inspired by a one-of-a-kind model from 1940, Reference 5930 combines two functions: a self-winding flyback chronograph and World Time – an iconic complication in the history and collections of the Manufacture. This model was launched in 2016 in a white gold version with a blue dial and matching strap.

Patek Philippe reinterprets this timepiece with a sporty and cosmopolitan spirit in a new version combining the brilliance of platinum with a green dial and strap. A combination of classicism and boldness that reinforces the personality of this cult model.

The names of the cities are printed in green on the corresponding disk. The green dial center illustrates the mastery of fine craftsmanship skills with a circular hand-guilloched circular pattern. This color is picked up at 6 o’clock on the snailed 30-minute counter. The applied hour-markers and the faceted Dauphine-type hands in white gold are highlighted by a luminescent coating ensuring good legibility in all circumstances.

The entirely hand-polished platinum case is set with a diamond at 6 o’clock. It features the “wing-type” lugs typical of 1940s-1950s World Time watches.

As caliber CH 28-520 HU is equipped with a column wheel and the modern disk-type vertical clutch, the central chronograph hand can also be used as a permanent (running) seconds display – thus ensuring minimal wear and tear and without affecting the movement accuracy or power reserve. The 4 o’clock pusher enables instant restarting of a timing operation when the central hand is already performing an operation (“flyback” function) or is being used as a permanent (running) seconds display.

The World Time function simultaneously displays the time in 24 time zones. When changing time zones, an exclusive patented mechanism enables correction of all displays by pressing the 10 o’clock pusher, without affecting the accuracy of the movement.

The new Reference 5930P-001 is worn on a shiny bottle green alligator strap with a platinum fold-over clasp. It is joining the white gold 5930G-010 version with blue dial and strap.
