Τεχνική σύγκριση.Παράθεση από: https://beckertime.com/blog/whats-the-difference-the-zenith-daytona-vs-the-rolex-daytona/It was what was going on under the hood that wrote the headlines. Rolex’s relationship with Zenith ended with the arrival of the Cal. 4130; a barebones, stripped back movement entirely of Rolex’s own creation—and one now recognized as possibly the finest mechanical chronograph caliber ever made.Taking their love of minimalist efficiency to new heights, the Cal. 4130 is made up of just 201 separate parts, a 60% drop on the El Primero, giving it the fewest components of just about any modern chronograph movement.To achieve it has taken a huge amount of creativity. While the Daytona’s exterior may retain a familiar look, the differences between the old and new calibers are legion. Elements such as the minute and hour stopwatch functions, controlled by two individual mechanisms in the Zenith movement, have been combined into a single module on the Cal. 4130. In doing so, it has freed up space for a larger mainspring, giving an uprated power reserve from 50 to 72 hours. It also means it can be adjusted with just one screw as opposed to five. In fact, in the entire unit, Rolex has only needed to use 12 screws rather than 40.Additionally, the ref. 116520 received new cutting-edge materials, with the antimagnetic Parachrom hairspring earning its debut. A niobium and zirconium alloy, it is impervious to temperature variations and offers up to 10 times the shock resistance of standard hairsprings. In 2005, it was upgraded again with a thicker oxide coating to protect its surface, one which reacts with the air and turns the distinctive color that saw it renamed the Parachrom Bleu.Ceramic ball bearings were used for the first time in the self-winding system too, seeing a 68% increase in winding efficiency.But the most revolutionary aspect came with Rolex’s use of a vertical clutch. The El Primero, along with just about every other mechanical chronograph movement, uses a horizontal coupling system to control the starts and stops of its stopwatch functions. With the Cal. 4130, Rolex arranged a pair of discs one on top of the other, running in a constant mesh with the drive train. Engaging and disengaging them with a clutch eliminates ‘backlash’, the tendency with horizontal systems for the chronograph hands to judder as they fight to gain purchase, giving a smoother and more exacting performance.It also means the stopwatch can be run for longer without it affecting the accuracy of the watch’s timekeeping, and it has the rare advantage of being removable, meaning it can be serviced to ensure its continued reliability.

As I just mentioned, Rolex PR told me that the caliber 4130 from the modern Daytona was regularly updated since its launch with little to no communication to customers. I couldn't believe it. After all, a lot of what we do at HODINKEE is fielding press releases from brands trying to create a story where there really isn't one. So, I reached out to a few friends at Rolex, and at competing brands, and no one knew anything. Then I spoke to a friend who is an independent watchmaker – he does not work for Rolex but does, with some regularity, work on them, in addition to watches from several other brands. He asked that he remained anonymous. Here is what he had to say:"Setting Dufour and Voutilainen level movement finishing aside, from a pure engineering perspective, Rolex's 3130 based calibers have reigned supreme for close to 30 years now. No mass-produced movement outside of Rolex comes close to matching their quality, durability, and reliability. They have come terribly close to defining the epitome of what a perfectly conceived mechanical watch movement should be.""Rolex took everything that was good about their 3130 series of movements and applied it to a chronograph. But they didn't stop there. They also took a long, hard, critical look at how they could improve upon the design thinking behind the 3130 to make it even more reliable. They looked at the weak points of the 4030, as well, and determined how best they could improve on what they had learned from it. The result was the 4130.""As for improvements on the 4030, there are several. Top five, in my opinion, would be:1. Vertical clutch 2. Modularity of automatic section 3. Full balance bridge with height adjustment nut 4. Single point of adjustment for the chronograph system (versus five in the 4030) 5. Parachrome hairspring – I believe it was there from the beginning, sans blue colour at the outset.""On top of that, they kept the goodness that was already in the 4030, such as the column wheel and free-sprung, microstella balance wheel (which Rolex equips all of its modern calibers with).""They didn't stop with all of that, either, though. Getting back to your reason for touching base: they have quietly been improving on the design since its debut at the turn of the millennium."He continued: "It is not unusual for Rolex to make incremental improvements to their calibers. The 1500 series went through multiple iterations over its long history. The 3000 series received small improvements, tweaking part tolerances. All of the ladies' calibers have also seen small improvements over the years. That's the Rolex way. Continually improving things, down to the smallest details. The upgrades to the 4130 haven't been mere tweaks, however, they bring notable improvements.""An 'upgrade' they did make some noise about was the blue Parachrom hairspring. As alluded to above, earlier 4130s were equipped with a white 'Parachrom' hairspring built on the same molecular foundation. Once proven and, in light of cutbacks from Swatch Group and its subsidiaries like Nivarox, it was important for Rolex to market this milestone in their vertical integration of production. More importantly, to me, the Parachrom hairspring was a serious horological leap forward in terms of precision and reliability of timekeeping.""They made a small upgrade to the train wheel bridge, modifying some of the components and the way that they operate upon it, to improve the reliability of the hour and minute counters. I would class this upgrade as being similar to the minor upgrades made to previous generations of Rolex movements.""A more notable upgrade that they introduced is a hairspring protection block, which eliminates any possible risk of the lower coils of the hairspring tangling in the hairspring's overcoil when the watch endures a hard blow. To the best of my knowledge, this was a horological first. I have never seen anything like it from any other watch company. It is stunningly brilliant in its simplicity and it does its job flawlessly. While the wearer of a Daytona may never notice it's there, they would quickly notice if it were not should the watch take a hard knock.""The biggest incognito upgrade are playless gears in the chronograph system. As I'm sure you already know, the vertical clutch system of the 4130 eliminates the jarring start of the second that can be noticed on chronographs that feature a lateral clutch when the chronograph is started. Playless gears take this to the next level, by eliminating backlash between gear teeth. In simple terms, backlash is a small amount of space, or 'play,' between the teeth of two gears that are interacting with one another, so that one tooth can disengage as another tooth moves in to continue to the transfer of energy.""A certain amount of backlash is necessary in any traditional gear system to prevent the gear train from binding and locking up. Unless the profiles of every single gear tooth are absolutely perfect (impossible), the spacing between the gears remains absolutely perfect (impossible), and there is zero play in the motion of the gears themselves (unlikely and inefficient), the tooth that is disengaging will become jammed between the tooth it is pushing and the tooth that is trailing it if there is no backlash. Thus, backlash was a necessary evil. To solve the issue, Rolex fabricates playless gears, one atom at a time, using a process known as LiGa (lithography-galvanoplasty). An additive manufacturing process. LiGa makes it possible to create gear forms that would be impossible to realize using traditional machining tools.""With this technology, Rolex was able to devise a gear form wherein the center of each gear tooth can be hollowed out, leaving behind two spring-like flanges that act as what would traditionally be the full tooth form. In this manner, both sides of the tooth can remain engaged with the gear it is interacting with throughout the entire duration of the tooth's transfer of energy, taking up any necessary play (backlash) in the hollow area in the center of the tooth.""MB&F made some fuss about LiGa gears when they launched the HM2. That was the first time I had heard of this technology, which Jean-Marc Wiederrecht / Agenhor employed for the retrograde minutes. Little did I know then that Rolex had already rolled out this technology, in relative mass production, with the introduction of the Yacht-Master II earlier that year. After proving itself in the wild, in the Yacht-Master II, the technology was introduced as an upgrade to the Daytona several years later, bringing absolutely fluid and seamless motion to the chronograph hands as they start and reset.""In sum, Rolex's 4130 represents the pinnacle of horological engineering. It is, arguably, the superlative in mechanical timekeeping. From its inception to its present incarnation, I have yet to encounter another watch movement that comes close to matching the thoughtfulness and attention to detail so evident in the 4130's design."So, how is that for an endorsement?
