nspired by a one-of-a-kind piece sold by Patek Philippe in 1927, a custom-made cushion-shaped split-seconds chronograph, the manufacture has now converted its Ref. 5372 into a new version for left-handers – a genuine first in its recent history.
The exclusive Ref. 5373P-001 combines a split-seconds chronograph with one of the most elaborate functions – the perpetual calendar that is perhaps Patek Philippe’s most iconic complication.
With a diameter of 38.3 mm, the platinum case is the same size as the Ref. 5372 but its crown (with an integrated chronograph monopusher) is at 9 o’clock and the split-seconds pusher occupies an unusual position at 8 o’clock.
It preserves its timeless elegance with the polished concave bezel that creates the perfect transition to the slightly domed sapphire-crystal back, the recessed and satin-finished case flanks, and the delicately curved strap lugs that merge with the bars almost seamlessly.
The indications (counters and apertures) of the dial are rotated by 180°: the analogue date at 12 o’clock, the subsidiary seconds at 3 o’clock, the moon phases at 6 o’clock and the 60-minute counter at 9 o’clock, complemented by the aperture displays for the day of the week and the month as well as the leap year cycle at 10:30 and the day/night indicator at 1:30.
Patek Philippe has also reworked the aesthetic appeal of the dial, introducing charcoal tones and a vertical satin-brushed finish. A sapphire-crystal display back (interchangeable with the solid-platinum back delivered with the watch) reveals the fantastic architecture of the CHR 27-525 PS Q movement with its two column wheels that bear two polished caps in the typical Patek Philippe style. The bridges, decorated with Geneva striping, are carefully chamfered and the edges are polished.
This watch is now the only remaining model with the CHR 27-525 PS Q movement that was formerly available in the Ref. 5372P-001 and 5372P-010; both models have been retired from the collection.
