Emmanuel, known as 'quattro' on WatchProSite, offers an in-depth look at the Patek Philippe Ref. 5470P-001, the 1/10th of a Second Monopusher Chronograph. His detailed presentation, featuring numerous high-quality images, provides a crucial foundation for understanding this technically advanced and aesthetically distinct timepiece. This article synthesizes community reactions to its design, finishing, and market positioning, making a 2026 forum discussion relevant to today's collectors.

And for those among us who like a sportier aesthetic and complication, here is the 1/10th of a Second Monopusher Chronograph, ref. 5470P-001.

The platinum case measures 41 x 13.68 mm



Blue varnished dial with applied white gold Breguet numerals (I think the following photos are more faithful to the texture of the dial than the one below).



Central 1/10th of a second hand in Silinvar®, red lacquered. Patented display ensuring fast and accurate 1/10th of a second reading.





White gold leaf-shaped hands with white luminescent coating.



Case design is based on ref. 5370





Diamond set at 6 o'clock



Calfskin leather strap embossed with fabric pattern, contrasted red hand-stitching and fold-over clasp.



High-frequency (5 Hz) movement CH 29-535 PS 1/10 incorporating all the “Advanced Research” innovations in the field of Silinvar® (Oscillomax® Ensemble)











The fit on the wrist

Neither the modern sporty aesthetic nor the fast running 1/10th of a second complication really speaks to me personally, but it's still an interesting and good looking watch.

What do you think?

About the Patek Philippe Split-Seconds Chronograph Ref. 5370

The Patek Philippe Reference 5370 is a split-seconds chronograph, a complication highly regarded in horology. It stands out in the Patek Philippe collection for its focus on a technically demanding chronograph mechanism without additional complications, presented in a classic and refined aesthetic. This reference appeals to collectors who prioritize mechanical complexity and traditional watchmaking.

The watch features a 41 mm case, available in either 18k white gold or 18k rose gold, with a polished bezel. It is equipped with the manual-winding caliber CHR 29-535 PS, a movement known for its innovative split-seconds mechanism and column-wheel control. The power reserve is approximately 65 hours. A sapphire crystal protects the dial and offers a view of the movement through the case back. Water resistance is rated at 30 meters.

This reference is notable for its enamel dial, offered in black or white, which provides a depth and finish characteristic of high-end watchmaking. The 5370 appeals to collectors seeking a pure expression of a grand complication chronograph from Patek Philippe, valuing its technical execution and understated design. It represents a significant offering within the brand's complicated watch lineup.

that red text on the dial was unnecessary the pusher should have been integrated in the winding crown I tried hard, really hard to count at least some sharp inward angles ... but failed And not a fan of the dial, the newest 5370 on the other hand has a magnificent dial and the 2 subdials should be perfectly aligned at 3 and 9, don't like them sunken to the bottom of the dial And I only accept luminova on a sports watch, and I mean a real sports watch ( daytona, nautilus, sub, RO ), this should b

The recent 5370R is much more appealing, even if the subdials are also placed below the 9 to 3 line. Best, Emmanuel

How they do it here and how they did it ( or still can if they take a bit more effort )

Do you know if the finishing of the 5370R movement is on a higher level? Best Thomas
