Patek Philippe 5470P-001: Tenths of a Second Monopusher Chronograph

The Patek Philippe 5470P-001 makes it possible to measure tenths of a second – a first for the manufacture. For intuitive reading of the time measurement, two hands make their rounds on the dial. The watch comes in a platinum case and has a sporty blue dial. Inside is an ultra-modern movement that combines 7 patents.

Platinum Case

The Manufacture put its new chronograph in a case made of platinum. The case measures 41 mm in diameter and 13.68 mm in height. It features slightly recessed and satin-finished case flanks that flow into curved lugs. The latter have decorative cabochons at the ends of the bars. Meanwhile, a domed sapphire crystal protects the front, which is set into a concave-shaped bezel.

As with all Patek Philippe platinum cases, the 5470P-001 features a flawless diamond between the lugs at 6 o’clock. On the back, the sapphire crystal case back reveals the mechanics of the sports watch. Alternatively, there is also a solid case back, which is in the box. In both cases, the water resistance is 3 bar or 30 metres.

The Sporty Dial

The dial of the 5470P-001 is made of brass and is lacquered blue. Applied are both the pearl indexes and the Breguet numerals in white gold. Meanwhile, a rail minute track winds around the dial. The time is indicated by feuille hour and minute hands in 18-carat white gold with luminescent coating. There is also a steel hand that measures the seconds of the chronograph and a red hand that indicates the tenths of a second. Furthermore, there is a small seconds hand at 9 o’clock and a 30-minute counter at 3 o’clock.

The New High-Frequency Movement of The 5470P-001

For this watch, the horologists developed a calibre that goes by the name CH 29-535 PS 1/10. It is based on the CH 29-535 PS, a chronograph movement with horizontal clutch and column wheel. To make the measurement of tenths of a second possible, the frequency of the balance increased to 5 Hertz. Despite the higher rate, the movement offers a power reserve of 48 hours. The escapement comprises the in-house Oscillomax ensemble, which achieves a rate accuracy of -3/+2 seconds per day.

The wearer starts a time measurement with the pusher at 3 o’clock. This button starts, stops and resets the chronograph. The measurement up to 30 minutes can then be read off the subdial. Decorations include bevelled and polished edges and Geneva stripes. There are also the gold-plated inscriptions “Oscillomax 5 Hz” and “GyromaxSi”.

Price & Availability of Reference 5470P-001
