In the perception of many people, the watchmaking status of Swiss famous fake watches is irreplaceable and unsurpassed in the watch circle. Irreplaceable is certain, but is it really impossible to surpass? In fact, it is not necessarily true. In recent years, both the German watchmaking industry and the Japanese watchmaking industry have been developing rapidly, and the watchmaking technology is visible to the naked eye. I believe this makes many Swiss watch companies have a certain sense of crisis, of course. , These words are not spoken out of thin air. Not long ago, the Japanese watch brand Grand Seiko launched a watch. It can be said that this is the “strongest masterpiece” of Grand Seiko, but can it really match the Swiss famous watch?
Grand Seiko, a famous Japanese watch, recently launched the brand’s first complex watch, the Grand Seiko Kodo constant force tourbillon.
Everyone knows Grand Seiko, which focuses on travel time performance and durability. Brand positioning is similar to Swiss best fake watches such as Rolex, Omega, IWC, and Panerai. But just like Omega has a central tourbillon and a chasing needle; IWC has a perpetual calendar with one-button adjustment and a constant force tourbillon; This kind of exclusive technical complex watch has established its status in the watch industry. Therefore, Grand Seiko also needs to have a complex watch with exclusive technology to elevate and establish its own position. Taking on this task is the Grand Seiko Kodo Constant Force Tourbillon. Today we will talk about what is different about this watch.
This constant force tourbillon is a constant force device added to the normal wheel train of the tourbillon watch. With a constant force device, through constant force gears and constant force springs, the power output by the mainspring is divided into sections of the same size, and then transmitted to the tourbillon. In this way, the power received by the tourbillon is equal and stable, so as to improve the accuracy of the travel time of the tourbillon. Of course, the main role is to “show off skills”. Including FPJ and IWC, they have launched constant force tourbillons before.
So what’s different about Grand Seiko’s constant force tourbillon? He is really different. It has two unique technologies:
1. Its structure is different. The Grand Seiko constant force tourbillon arranges the constant force device and the tourbillon coaxially. The constant force device and the tourbillon share the same axis. The constant force device cage is outside, and the tourbillon cage is inside. The two blend together.
2. In operation, the Grand Seiko constant force tourbillon, the inner tourbillon rotates normally, and the outer constant force device cage jumps every second (just like a quartz watch). Once a second, equal power is transmitted to the tourbillon.
Technically speaking, the closer the constant force device is to the tourbillon, the better. Why do you say that, the closer you are, the less power attenuation will be. Before Grand Seiko, the constant force tourbillons of other famous watch brands were mainly installed on the travel time train, so that they were far away from the tourbillon. This time Grand Seiko directly installed the constant force device on the tourbillon, which is very powerful. Furthermore, the Grand Seiko constant force tourbillon, the inner cage rotates normally, and the outer cage jumps every second, which is not available in other companies (IWC has a similar form, but it can only keep the first two days of full winding. seconds and resume rotation after two days).
The complete set of components of the Grand Seiko Kodo constant force tourbillon, the outer constant force device, the main components are constant force gear and constant force spring; the inner tourbillon is the normal tourbillon.
Now put the outer constant force device on the inner tourbillon, OK, the two are combined into one.
The inner tourbillon of Grand Seiko rotates normally. During the rotation, the constant force gear will be stuck/released. The constant force gear has a total of 5 teeth, and the 1 second hand of the tourbillon is stuck/released, so the outer constant force device , it will jump every second. And not only the constant force device jumps every second, but the gears of the entire transmission train train jump every second.
Since the entire transmission wheel train jumps every second, why can the inner tourbillon rotate normally? This is because the power of the inner tourbillon is provided by a constant force spring alone. The constant force spring in the constant force device is under the tourbillon. Following the rhythm of the constant force device jumping every second, the constant force spring is tightened/released to provide power to the inner tourbillon so that the tourbillon can rotate normally.
The basic principle of the Grand Seiko Kodo constant force tourbillon is the above. Grand Seiko’s constant force tourbillon is unique in the world of famous perfect replica watches.
Whether it is from structure to performance, it represents the highest level in the current constant force tourbillon.
This constant force tourbillon is not only the first tourbillon of Grand Seiko, but also the first skeleton watch of Grand Seiko. Needless to say, everyone can see that the appearance of the Grand Seiko constant force tourbillon is very high. The whole watch has an eccentric layout, a large area of hollowing out, and unique Japanese decorative elements are used in the detailed decoration.
The upper part of the watch is the hour hand and minute dial, which is hollowed out, and you can see the parallel double barrels below (the two barrels provide power to the wheel train at the same time). The drive train runs through the center of the dial and connects to the constant force tourbillon below. The entire dial is symmetrically balanced from left to right, and even the power display at 8 o’clock can echo with the dial wheel train at 3 o’clock.
The surface of the watch is polished, brushed, and pearled to form a magnificent light and shade effect. Among them, the chamfer of Grand Seiko is “cut” and polished at 45 degrees, with sharp lines, which is different from the smooth effect of Swiss watches.
Even in the complex hollowing out, the hands and hour markers with multi-angle facets are very eye-catching.
In terms of details, we can see that the two barrels of the Grand Seiko fake constant force tourbillon, the balance wheel of the movement, and the gears are all made of the common “three-headed” pattern in Japan, which is not seen on Swiss watches. of. The screws on the watch have 6 notches, which are different from the most commonly used flat-head screws on Swiss watches.
In the basic configuration, the Grand Seiko Kodo constant force tourbillon measures 43.8 mm and is 12.9 mm thick. The case has two layers, the inner layer is a platinum case, and the outer side has a titanium case to protect the platinum. For this watch, the size and thickness have been well controlled, and it is even waterproof to 100 meters.
The movement model of this watch is 9ST1, limited to 20 pieces, manual winding, swing frequency 28800 times/hour, power 72 hours, standard travel time error of +5/-3 seconds per day.
