Left-Handed Patek Philippe Split-Seconds Monopusher Chronograph Ref. 5373P-001

Launched in 2010, the manually wound CHR 27-525 PS Q caliber has established itself as the thinnest split-seconds chronograph and perpetual calendar movement ever produced (7.3 mm thick). Since 2017, it has been offered in a platinum model with a sunburst blue dial (5372P-001) or a rose-gilt dial with a vertical satin finish (5372P-010).

Inspired by a one-of-a-kind 1927 timepiece, Patek Philippe has created a new, highly original version of this timepiece designed for left-handers: a first in the recent history of the Manufacture. This further enhances the exclusivity of the split-seconds chronograph, one of the Manufacture’s most sought-after Grand Complications.

The platinum case can be distinguished by its crown (with integrated chronograph monopusher) located at 9 o’clock and its split-seconds pusher placed in an original position at 8 o’clock. It retains its elegance, with a polished concave bezel providing a perfect transition to the slightly domed sapphire crystal, recessed and satin-finished flanks, as well as finely curved lugs and spring bars adorned with decorative cabochons.

Patek Philippe has also reworked the aesthetics of the charcoal gray dial with a black-gradient rim, inverted counters/apertures and snailed ebony black counters contrasting with the vertical satin-finish decoration. The chronograph displays (central chronograph and split-seconds hands, 60-minute counter hand at 9 o’clock) are distinguished by their red varnished color. 

On this model, the small seconds counter is positioned at 3 o’clock and the moon phase at 6 o’clock, while the two round apertures for leap-year and day/night indications respectively appear between 10 and 11 o’clock and between 1 and 2 o’clock.

The sporty and contemporary touch is also expressed in the black calfskin leather strap with embossed fabric pattern and contrasting red stitching, equipped with a platinum fold-over clasp.

The new 5373P-001 comes with an interchangeable sapphire crystal and solid case backs. Like all Patek Philippe models in platinum, it features a brilliant-cut diamond set in this instance at 12 o’clock. This new Grand Complication model replaces References 5372P-001 and 5372P-010.
