Patek Philippe Introduces the Ref. 5470P 1/10 Second Chronograph
High tech and sport.replica watches for sale
Just after Watches & Wonders 2022 came to a close – the day after the show, in fact – Patek Philippe unveiled one of the year’s technical highlights, the 1/10th of a second chronograph. 5470P-001.
A first for Geneva watchmakers, this chronograph is equipped with a high-frequency balance wheel that vibrates at 36,000 vibrations per hour, or 5 Hz. The high-beat movement causes the seconds hand to circle the dial every 12 seconds, enabling the chronograph to record elapsed time with precision (unless the user makes a mistake) with a resolution of 1/10 of a second. This lightning second hand runs in sync with the regular chronograph second hand, creating an unusual sight on the dial while the chronograph is running.
While lightning seconds chronographs have been made before, it's surprising to see a legacy brand like Patek Philippe experiment with complications. The feature is often associated with brands such as TAG Heuer and Zenith with sporty, modern aesthetics.luxury replica watches
In terms of aesthetics, ref. The 5470P is another example of the brand continuing to move towards a more modern, eye-catching style, even for other classic models. But under the hood is where it shines.
While the idea of attaching an additional gear train to the 1/10-second hand may seem simple, the movement inside has undergone a seemingly complex modification. In typical Patek Philippe fashion, complications incorporate several patented innovations that contribute to reliability and ergonomics.
In fact, reference. The 5470P marks the first time that Patek Philippe has placed an "advanced research" Oscillomax balance wheel assembly in a regular production model (previously only found in ref. 5550P). The Oscillomax consists of more functionally efficient silicon components that help increase power reserve (about 50% in the case of cal.240 Q in the 5550P) and enhance reluctance.
On top of that, Patek Philippe has applied for seven patents to perfect the 1/10th of a second display, most notably the double pendulum shock absorber that keeps the chronograph engaged in the event of an accidental impact.replica Richard Mille RM 011
With most high-end brands focusing on classic decorative features, it's good news that Patek Philippe continues to innovate with fresh engineering ideas. That is, the referee. The 5470P does feel like an extremely complicated and expensive solution to a problem no one has asked.
Nonetheless, referee. The 5470P certainly echoes the brand's unspoken message at Watches & Wonders 2022, and it's a fact that it's more than just an integrated bracelet sports watch.

Internal reference. The 5470P is the CH 29-535 PS 1/10, and it is based on the CH 29-535 PS, the brand's workhorse hand-wound chronograph movement, which serves as the basis for various additional complications, such as rattrapante.
The CH 29-535 PS 1/10 features two major modifications to the base movement - the standard two-button setup is now a single button, and more importantly, the addition of a 1/10-second chronograph module on the back.Breitling Endurance Pro replica
This means that the watch still retains the regular chronograph function, with a central passing seconds hand and a passing minute counter at three o'clock. However, the addition of this module provides a central lightning seconds hand that runs in parallel with the regular chronograph seconds. This results in good legibility, as regular seconds and 1/10 of a second can be read from the large scale on the edge of the dial.
Both layers of the chronograph—the standard stopwatch and the fractional second—use a lateral clutch. As a result, movement designers had to address the shortcomings of the lateral clutch – the challenge of ensuring smooth engagement when starting the chronograph.
This problem is further exacerbated by 1/10 second wheels, which require precise angular positioning and consistent, correct engagement when in use. This has led to a number of related innovations aimed at addressing these issues.
First, the brand uses a pair of spring-loaded anti-backlash gears on the drive wheel of the 1/10-second hand, reducing the play between the gear teeth for precise starts and stops.replica Ulysse Nardin Freak Watches
The two chronograph clutches are stacked on top of each other and appear heavy and thick. To ensure that the chronograph does not disengage due to the inertia created by the shock, a simple but clever idea was patented - the base clutch has a hook that locks the clutch to the column wheel when the chronograph is engaged.
Meanwhile, the Lightning Second clutch requires a similar mechanism to stay in place when engaged. It holds what is arguably the most novel patent in a movement – a complex double-pendulum shock absorber that tightens on impact to keep the clutch firmly engaged while the chronograph is running.
Furthermore, since the movement is high-beat and also suffers from the extra load created by the 1/10th of a second module, energy saving becomes critical. One solution is a redesigned barrel arbor, which accommodates a stronger mainspring and contains more energy when fully wound.
Of course, another feature is the lightweight silicon parts, such as the Oscillomax balance wheel assembly, which includes a balance wheel, escapement, and a silicon balance spring. Interestingly, the lightning second hand is also made of silicon, so it consumes half the energy of a normal brass hand.www.moon-watch.co
