Early 1950s, Patek Philippe Pilot's Chronograph with Split Seconds

The Patek Philippe 5070 is based on an equally mysterious 46mm chronograph the famous reference 2512 Pilots Chronograph with Double Rattrapante Luminous Dial, from the early 1950s and now housed in the Patek Philippe Museum. Now for the fun: While it's well documented that Philippe Stern based the design of the 5070 on a stunning oversized chronograph with a gold case, black dial, luminous Arabic numerals and a bold tachymeter scale, there's nothing more to Patek Philippe In 2000, Philippe Stern bought the watch for CHF 1,439,750 at a Christie's auction. This means that Philippe Stern became deeply enamored with the watch long before he bought it and gave it proper priority at the Patek Philippe auction. museum.

It is also interesting that both the Ref. 2512 and the 5070 faced the same design challenge of how to take a smaller chronograph movement and design a very large chronograph watch while maintaining a balanced dial. In the 2512, this is the caliber 13-130 based on the Valjoux 13 caliber, which measures 13 lignes or 29 mm; the 5070 is powered by the CH 27-70 caliber, which is based on the Lemania 2320 and measures 27 mm in diameter. The problem, of course, has to do with the placement of the pinions for the chronograph minutes and running seconds, which, when placed in an oversized case, can suffer from "cross-eyed" syndrome, where their corresponding subdials feel as though they are too close together . high quality watches replica

To overcome this design challenge, Philippe Stern drew inspiration from the solution presented by reference 2512. Stern uses an oversized tachymeter combined with a bold seconds track that takes up extra space between the chronograph subdials and the oversized case bezel. If you look at the image below, which shows the first example of the 5070, which follows the combination of the gold case and hour markers and black dial found on the reference 2512, you will see that the design, lettering and proportions are very close in proportion. The case of the 5070 also closely follows the case style of the 2512 model, with its bezel stepping considerably from the case itself, which further breaks up the space from the center of the watch to the perimeter of the case. case.

The design genius of the 5070 lies in the use of circles radiating from the center of the watch, each of which becomes a defining part of the design space. First, there are Arabic numerals adorning the inside of the dial. Next is the speedometer. Then, the seconds track is styled in a bold chemin de fer (or railroad track). Then came the bezel and finally the shape of the case. Together these circles create the effect of radiating ripples on the pond, creating a dynamic but very harmonious effect. Incidentally, this is also the design code Thierry Stern used when designing the 5970. The 5070 is only the second water-resistant chronograph created by Patek Philippe, and it holds a very special place in the hearts of collectors for its unusual design. , beyond the lure of life. replica luxury watches

Whiteboard CH 29-535 PS
The importance of hand-wound chronograph movements to Patek Philippe cannot be overemphasized. It has powered two timepieces throughout the brand's history and defined the early vision of the Stern Brothers. Introduced in 1936, just four years after the founding of the Sterne dynasty, reference 130 defined the modern gentleman's chronograph. The reference number 1518 perpetual calendar chronograph launched in 1941 not only represented the world's first serialized high-complexity wris****ch, but also defined the appearance of complex wris****ches. It can be said that this stunning chronograph set the aesthetic code for every complicated watch in the 20th century. Thierry Stern said: "The chronograph is of paramount importance to Patek Philippe. This complication has contributed enormously to defining our identities throughout the 20th century and will continue to do so. function until the new millennium. With the task of Patek Philippes first in-house hand-wound chronograph movementthe mighty CH 29-535you can be sure that not only Thierry Stern but also Patek Philippe ) was deeply felt by everyone at the Manufacture of Plan-les-Ouates, and even Stern's predecessors watched with interest in the horological Valhalla.high quality cheap watches

I've always found Patek Philippe's pragmatism in naming its movements amusing, as they simply and unemotionally describe the height and girth of the movement. If we named humans the same way, I'd be Mr. Five Foot Nine - 175 lbs. Hence, the CH 29-535 is named for its dimensions, specifically, its diameter of 29 mm and its height of 5.35 mm. However, this is not Patek Philippe's first in-house chronograph movement. That honor belongs to the automatic vertical clutch-driven caliber CH 28-520 in the Annual Calendar Chronograph Ref. 5905. But it is important to understand that the concept of this movement is completely different. With its self-winding function, column wheel-driven vertical clutch and silicon hairspring, escape wheel and lever, it is Patek Philippe's high-performance, ultra-sturdy sports watch chronograph movement. By contrast, the hand-wound, transversely-coupled CH 29-535 caliber is a work of horological elegance rather than an exercise in pure performance like the CH 28-520. If you want an analogy, the CH 28-520 is the equivalent of a 118-foot WallyPower yacht, while the CH 29-535 is the world's most elegant sailing yacht.

So what's so amazing about the CH 29-535 PS? Let's see why. As described by Thierry Stern, it was designed with enough power to add any complication without difficulty, such as a perpetual calendar, a split-seconds function or both , as is the case in the magnificent 5204. Part of this can be attributed to the frequency of movement. The upcoming Lemania CH 27-70 oscillates at a vintage 18,000vph, while the CH 29-535 PS oscillates at a very modern 28,800vph. This higher oscillation speed gives the balance wheel greater autonomy and is immune to the micro-shocks that the luxury cheap Watches is almost constantly exposed to during normal wear. Coupled with an enhanced 65-hour power reserve (40 hours for the CH 27-70) and stronger, more consistent torque qualities from the mainspring,

The CH 29-535 also features a precise jumping minute counter. This is a minute counter that only jumps forward by one minute at the exact moment the chronograph seconds hand passes the 60-second mark. In other chronographs, the minute counter hand creeps forward gradually, or if it does jump, it may take a second or two to complete this movement. Accurate jumping minute counters require the addition of a complex mechanism consisting of a snail cam attached to the seconds wheel, a ruby stylus placed on the cam and falling off the edge of the cam every minute, activating the minute counting lever to pull the minute counting lever. The timing and sub-wheels are precise. While the Lange Datograph is the first and only hand-wound chronograph movement to feature this additional complication, Patek Philippe's precise jumping minutes counter features a completely redesigned snail cam profile, as well as the The lever powers the oversized coil spring, which applies less spring tension, thereby transferring less friction to the snail cam. Consequently, the systems in the CH 29-535 PS place much less load on the movement.replica Audemars Piguet Royal Oak

All laterally coupled chronographs suffer from what is commonly referred to as "chronograph gap". At this point the drive wheel is in contact with the chronograph second wheel. Since both wheels have teeth, there are moments when the teeth touch each other point-to-point. This causes the teeth of the drive wheel to slide forward into the space in front of the teeth of the timing wheel or back into the space behind the teeth of the timing wheel. On the front of the watch, the seconds hand appears to jump slightly forward or backward. If the goal of a watch is to be accurate to fractions of a second, every time this happens, you might think that the overall accuracy of the event being timed is affected. For the CH 29-535, Patek Philippe created an entirely new tooth profile for the chronograph and drive wheels to eliminate backlash, since point-to-point contact is no longer possible. In the end, it created a very simple system to adjust the depth of engagement between these two wheels, using an eccentric cam that acts as a cover over the movement's column wheel. Lets take a look at six amazing patents that Patek Philippe applied for while creating the CH 29-535. replica Jacob & Co. Astronomia Gambler
