The Magic of the centered Hairspring’s center of Gravity

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.

Replica Seiko 6159 Tuna Original

On the off chance that you’ll permit me to wax a bit, we discuss vintage observes today for the most part from the viewpoint of what they look like – well, today. Without a doubt, we talk about how the watch came into generation, any specialized developments and why it was made. What we regularly miss, in light of the fact that the data once in a while exists, are the firsthand discernments that existed replica watches around a brand or model amid its real generation date. In the event that I had a time machine, beside purchasing everything (and obviously modifying the time-space continuum), I’d affection to perceive how certain brands were advertised, how they contrasted with others, and so forth., and so forth. While it’s reasonable a gross exaggeration, a percentage of the watches we really grovel over may have been seen as what might as well be called today’s Michael Kors pieces! Thus, yes, I get amped up for conversing with individuals about the past and why they picked certain watches.

It was just for recreational plunging, yet not all simple bounce in and go. I did numerous strenuous jumps from rocks and magma streams in changing tide and surf conditions and as profound as 165 feet, max on compacted air. This watch with its size was anything but difficult to peruse in all conditions and the ergonomic bezel fast to set. They (Replica Seiko Watches ) considered everything to make it confront the rigors of substantial use, bore witness to by the execution today, after 40 years, despite the fact that it invests a great deal of energy in my work area drawer. I’ll presumably never part with it… recollections, you know.

Today’s short record, however, is truly around a peruser who posed a few questions on where to fake watches administration a Seiko symbol, the 6159-7019 unique ” Grandfather Tuna”. We had an any longer audit on this watch not long ago, yet felt you’d like to see pictures and hear the tale of a unique proprietor piece.


2016 Basel Watch Fair, Rolex released a new ceramic ring Daytona is welcomed by the public, but the introduction of new Air-King Air King 116900 is completely beyond everyone’s expectations.

Rolex’s “Air-King Overlord”, is the Rolex Oyster Perpetual Series of the most basic entry watch, only the most basic junior needle, no calendar window, the price is also the most approachable.

Rolex Air King 116900 solid steel strap and oyster-style clasp and Rolex Explorer is exactly the same, but pricing is cheaper, for 5700 euros, Explorer pricing for 6000 euros, compared to the same magnetic properties of MILGUASS cheap 20 %, Which makes it a truly super-cost-effective entry Rolex watches.

The new rolex replica watch ref. 116900 is fitted with a 904L stainless steel case measuring 40 mm in diameter and paired with the signature Rolex Oyster bracelet and a smooth polished bezel. The watch is waterproof to 100 meters and its movement is properly protected by its Twinlock screw-down crown and its screwed-in solid case back. The watch is fitted with a sapphire crystal with Rolex’s etched coronet at 6 o’clock.

Replica IWC Aquatimer watches

I was among the first one to show you the IWC Aquatimer Replica Watches novelties. Today I photographed the watches under much better conditions and I invite you to rediscover the entire collection.

I am sure you have already seen the IWC Replica 2014 on my blog. I took these pictures in the Sultanate of Oman end of October under not ideal light conditions. I was happy to have these shots, but one can do much better of course.

When I presented you the IWC Aquatimer novelties as a SIHH 2014-preview I did not yet have the official technical data by hand. Today I got them and here they are for you to be discovered.
Advancing the dials of three displays simultaneously isn’t easy. We couldn’t overcome the laws of physics, but we’ve managed to use them cleverly, stated Stefan Ihnen, IWC´s Technical Director. Do not miss this episode! I invite you to discover it here.Even if this is not the most complicated mechanism IWC Replica Watches ever conceived it is my absolute favorite one. It combines a chronograph and a perpetual calendar with a digital indication for the date, month and leap year. That’s just gorgeous and in daily use extremely useful, since both, date and month, is perfectly readable.

Replica Portugieser Annual Calendar Watches

After the Portugieser minute repeater, the Portugieser 7-day power reserve, the Portugieser perpetual calendar, the Portugieser Tourbillon Mystère, the Portugieser constant-force tourbillon and the recent Portugieser 8-day hand-wound movement it is now the Cheap Replica Watches that starts to court for the sought after and limited space on our wrists.

The Portugieser Annual Calendar is powered by the new IWC-manufactured 52850 calibre. The watch symbolizes the launch of an IWC initiative to produce further series of in-house calibre families in the years ahead. Located at “12 o’clock” on the dial, IWC Replica annual calendar shows the month, date and day in three separate, semi-circular windows. The switching mechanism automatically takes into account the differing lengths of individual months. Unlike a perpetual calendar, however, the annual calendar is unable to factor in the differing length of the month of February or the leap years. Once a year, then, at the end of February, it requires manual correction. For the development of the annual calendar module, IWC’s watch designers ensured that the correction could be carried out easily and conveniently using the crown


Across the entire Cheap IWC Replica family, the rotors have been made slimmer, while the bridges are more open and inset with a solid gold “Probus Scafusia” medallion. This way, even more details of the movement with its two barrels can be seen. The improved Pellaton winding system with the practically wear-free components made of black and white ceramic is also clearly visible.Thanks to this elegant solution, the engineers were able to dispense with a corrector, which would have compromised the IWC Replica Watches Annual Calendar’s purist design.
With its voluminous 44.2-millimetre case, grooved bezel, classic railway-track-style chapter ring, slim feuille hands and almost unchanged Arabic numerals, the Portugieser Annual Calendar very closely resembles the original Portugieser of 1939, a veritable design icon.The small seconds subdial, however, is not positioned at “6 o’clock” as in the original, but at “9 o’clock”. The subdial on the opposite side contains the power reserve display. I am pretty sure that the rare combination of an annual calendar and 168-hour calibre will make this latest complication an attractive for watch connoisseurs.


When this exquisite namely, 32.7 mm and 27.4 mm in two dimensions, the material also has 18K red gold and gold options. Two kinds of dial design individual charm: simple models dial with white mother of pearl dial decorated with diamond hour markers; and luxury models are based on this to gold butterfly Adds a point of luxury.
