Not only the perpetual calendar complication makes up for the price of CHF105,000 Swiss Francs, also the fact that this Nautilus 5740/1G is made of white gold helps. The /1G indicates the use of white gold, for those unfamiliar with the reference codes by Patek Philippe. Gold has also been used for the moon phases disc for example. This disc, made of sapphire, has two gold moons and a number of stars on there.

With the addition of the perpetual calendar to the Nautilus collection, Patek Philippe combined their iconic luxury sports watch with a superb complication. Although in my opinion they also did that already with the chronograph. The chronograph is an often underrated complication in terms of complexity. However, the aesthetics are quite different of course. Where the chronograph always adds some bulkiness due to the extra pushers for operating the movement, the perpetual calendar only needs a few very small correctors that can easily be hidden in the case band.

In my opinion, Patek Philippe did a marvellous job by keeping the aesthetics of the Nautilus as modest as possible. A thin case made of white gold, a beautiful blue dial with the typical Nautilus motif and only a dial that reveals the grand complication. The white gold has, of course, this soft glow that you won’t find on the stainless steel versions of the Nautilus. But only those who know will identify it as a white gold watch, and most probably because of the dial layout that shows there’s more going on than just three hands and a date aperture.

I’ve seen the vintage Nautilus 3700/1A approaching the €100.000 mark, and although  I see the beauty and ‘collector’s passion’ for that reference, I would certainly spend my own money on this perpetual calendar for the sake of combining one of the most beautiful watch designs in the world with one of the most interesting complications in the world, both by Patek Philippe.

The Patek Philippe Nautilus collection consists of 33 different watches today, the newest model being this Nautilus 5740/1G, or the ‘Nautilus Perpetual Calendar’. The Nautilus 5740/1G is actually the first grand complication in the collection. While the ‘simple’ three-hand Nautilus 5711/1A is the most wanted reference, there is also a date & moon phase model (reference 5712), an annual calendar (reference 5726), a chronograph (reference 5980) and a chronograph & dual time model (reference 5990). And now a perpetual calendar complication has been added to the Nautilus family. What used to be considered as the enfant terrible of this Geneva manufacture, has now become one of the hottest watches in the world. Instead of creating limited editions of all sorts, Patek Philippe chooses to keep the production limited, while the demand is high. Very high. It is simply not available, see the first paragraph of this article.

Rate precision from Patek Philippe’s perspective

One of the successful outcomes of the Patek Philippe Advanced Research project involved a significant reduction of the negative impact of the center – of – mass imbalance on the isochronism of the balance spring itself. A glance at the Spiromax ® balance spring made of Silinvar ® shows that the outer boss is now paired with an inner boss. The outer boss, also referred to as the Patek Philippe terminal curve, improves the isochronism of the balance in all positions by assuring the adequately concentric expansion and contraction of the balance spring. It compensates the disruption of isochronism caused by the escapement and the rotation of the balance regardless of the amplitude. Conversely, the inner boss offsets positional changes of the center of gravity to assure the highest possible rate accuracy in vertical orientations. For the owner, this means that the watch will not run slower or faster regardless of its orientation. The production of hairsprings with the DRIE process guarantees a perfect reproduced geometry, including the positional changes of its center of gravity. Because silicon cannot be deformed, its properties are not affected even when the watch is worn daily. The precisely defined geometry of the inner boss causes a controllable position change of the center of gravity while the spring contracts and expands. This significantly reduces or even eliminates the center – of – mass imbalance of the hairspring during each semi – oscillation. The result is a degree of rate accuracy that exceeds nearly all standards for mechanical watches regardless of their orientation.

Rate precision from Patek Philippe’s perspective

The Patek Philippe Seal imposes very stringent requirements on all of the manufacture’s mechanical watches. The mean rate of movements with a diameter of more than 20 mm must range within – 3 to +2 seconds per day. For Patek Philippe tourbillon timepieces, the tolerance is a strict 3 seconds per 24 hours. Hundreds of repetitive measurements performed by Patek Philippe’s certification laboratories have shown that a mechanical Patek Philippe movement with a Spiromax ® balance spring that has both an outer and an inner boss can be adjusted to a mean rate of – 1 to +2 seconds per 24 hours, which matches the rate accuracy of a Patek Philippe movement with a tourbillon.

Trailblazing technologies for a promising future

The new Spiromax ® balance spring with an inner and outer boss reconfirms the extraordinary benefits of Silinvar ® , the silicon derivative that Patek Philippe launched in 2005 as a world debut. Machining it with the DRIE process allows the geometry of the hairspring to be al tered at any location to systematically influence its oscillation behavior and thus its isochronism. This is an ambitious goal because a precise and dependable rate is an important prerequisite for assuring the successful future of the proud tradition of mechanical timekeeping. For this reason, Patek Philippe’s objective is to gradually integrate the balance spring with this geometry in its current production schedule. But Patek Philippe Advanced Research also extends to other fields as illustrated by the n ext innovation within the framework of this presentation.

It is interesting to note that the simple mention of the brand Patek Philippe always seems to create a lasting impact on most people. This brand of luxury timepieces has long been resting at the top of the Swiss watches list, undisturbed by the stiff competition that thrives in the country of dedicated manufacturers. Through the years, Patek Philippe watches have earned the adulation of the high society, including the royalties from different parts of the world.

The name of the company, which was coined from the owners Antoni Patek and Adrien Philippe, has built a strong reputation in the industry of watchmaking. Since the brand was founded in 1868, Patek Philippe has become one of the frontrunners in the development of the trade. It helped in the innovation of the movements and designs for pocketwatches and wristwatches.

Patek Grand Compilations Copy

In general, Patek Philippe replica watches may include two or more features such as the perpetual calendar, moonphase display, split-second hands, minute repeaters and chronograph. One of the most complicated Patek Philippe watches is the 24-function pocketwatch that was sold at an auction for a whopping US$11 million. Aside from the technologies applied to the watches, the elegance of the metals and precious stones also add to the defining qualities of the brand.

The milestones in the production of Patek Philippe copie watches are greatly impressive. From the royalty to the popes, the clientele of Patek Philippe remains unparalleled. The famous Queen Victoria of England had received a number of exclusive watches from the company since 1851. Soon, the brand Patek Philippe has flourished throughout the kingdoms in Europe, making it the official supplier to some political figures and even the popes.The company currently holds the world record having the most expensive pocketwatch and wristwatch ever sold at the auctions. With the kind of people that it serves and the price that it demands from the buyers, it is not surprising that Patek Philippe has become an authority in Swiss luxury watches.

Most of the men’s watches made by Patek Philippe are devised with more complications as compared to those timepieces designed for women. Perhaps the most popular line of watches under the brand is the Calatavra collection. Its trademark design is the round-shaped case with hobnail bezel. However, the additional features as well as the movements of the watches still vary from one to another; they can be automatic, manually wounded or quartz.
