Remember that, when LVMH Group acquired Zeni in 2000, many cousins began to disappoint Zeni’s stamina. In fact, in the next few years, they are basically making some very different styles. The watch models make this view even stronger. Fortunately, people gradually get used to the changing style of Zeni. Another reason is that people not only play with style, they also have technology. Just like the zero-gravity watch we talked about before, it is characterized by a unique orange and metallic hue cooperation model. The unruly color grading used on this type of high-end watches and the technical interest we have always seen in the Zero G tuning system, which is also part of their home-made mechanical movement. This is not a 3D tourbillon. The ‘Zero G’ system (formerly known as the ‘Zero G Tourbillon’ although it is not a real tourbillon) is an interesting concept. Zenith has used this system in one way or another for almost 10 years. . It is worth noting that Zenith in 2018 has overcome the design problem of placing a large bubble-like space on the movement to place this system. This issue can be a big deal for collections. In addition to this limited edition Swizz Beatz Defy Zero G, Zenith also plans to release some other versions of the Defy Zero G watch. Zenith has been struggling to use this Zero G system on classic or modern style watches, so it has been hovering. This ‘Tourbillon Zero G’ was first used on modern timepieces, and later on some classic-style watches. This movement was seen on the Zenith Defy-style case in 2018. return. This movement is Zenith El Primero 8812 S, which can be seen through the completely hollowed-out holes. This design is inspired by a very heavy Hublot style. Making luxury watch brands more modern and younger, the ability to revive these brands has proven to be right. It is the most effective response to the complex proposition of how to operate a traditional mechanical watch brand today. The 8812 S is an El Primero movement, which means a ‘fast’ operating frequency of 5 Hz (36,000 rpm). It is really shocking to have this movement on this watch. In addition to faster running speed, the escapement system is also included in a tuning balance style adjustment system. The basic concept of this system is that the escapement always faces up even when the wearer’s wrist is moving, because there is a balance ring system weight at the bottom. The calibration system is affected by gravity and therefore operates differently at different locations. On a clock, this thing doesn’t matter, because that kind of equipment is always fixed in one place. What’s the use of keeping the tuning system up? On the watch, it’s critical because the orientation of the tuning system changes as the wrist moves. The concept of the Zero G system is to keep the tuning system always in the same position or orientation, so theoretically it is often more accurate. Therefore, the purpose of the Zero G system is to improve the accuracy of mechanical watches. Old Deng said: Does it work? I’m not quite sure. I mean the movement is working properly and it is normal when reading, but it is difficult to assess how much performance improvement this system has actually achieved. Although the idea of always keeping the tuning system in the same position is powerful, how it works in reality, and that turning when the wrist is moving means that the tuning system is more stable or unstable. In addition, adding extra parts to the gear chain often means an increase in mechanical inefficiency. Power is transmitted to the calibration system, and then transmitted with as little loss as possible. It is an interesting question how well this system performs on the parts list of a traditional mechanical watch.
