Fashion Watch Trend Report: 1931, published a ROLEX Perpetual Rolex watch, the thickness of 7.5mm, it is the world's first automated disc can watch 360-degree rotation, but only one-way on the chain.
Automatic course of development
1770, Abranham-Louis Perrelet created a self-winding watch, shortly after Abraham-Louis Breguet was modified but not widely used, so self-winding watch has not yet born. Later, to the early 1920s, John Harwood has developed the first self-winding watch and patented, but then Harhood self-winding watch produced is still a semi-automatic watch hit Tuo; and the so-called hit Tuo-style, that is, it is not able to complete 360-degree horizontal rotation, and we are now using a self-winding mechanism is still different. ROLEX in 1931 until the introduction of a water feature with self-winding automatic watch before I really make a 360 degree rotating disk, while While this is called "perpetual rotor " The movement is widely equipped in three Friday's Rolex bubble back into the watch, but it is still only one-way on the chain, the chain of two-way R & D to come out to ten years before, which makes automatic chain can be more efficient. Self-winding mechanism for the subsequent continuous improvement, to the movement of the 1950s began to do light, some watchmakers began to use gold or platinum as an automatic plate material, the higher the weight of the feature makes the watch to become thinner and because can help the performance of the chain, which is self-winding several important milestones in the development.
Automatic structural components of the name: 1. Automatic plate, 2. Automatic rotation, 3. And 4. Automatically some wheels (both coaxial), 5. And 6. Auto two fan wheels (two coaxial), 7 . Automatic wheel San Francisco, 8. automatically quadruple round, 9. Large vehicles (ie large drum), 10. barrel.
Bi-directional automatic winding mechanism
The picture above shows the use of two double two-way on the back wheel of the automatic winding mechanism for refining. Two-way on the chain is a more complex structure, but in fact the principle of transmission are interlinked with one-way, we can clearly see the direction of automatic chain gear, when the automatic plate 1. To rotate, this time with coaxial Automatic round 2. will rotate in conjunction with the direction of homeopathy, and its phase two double bite back wheel 3.4. and 5.6. idling through the rotation mechanism to promote and will triple their round 7. push ahead, and then transfer to four fan wheel 8., the following four rounds of the small fan gear again and Large car bite, the winding on the chain, which is a complete program. In fact, two-way on the chain have a basic concept, it must have two sets of gear with each other for a cover of the rotation in order to produce two sets of gear turns forward on the chain effect. In fact, each of the two gears, a brand of how to turn on the chain of different designs, a similar way clutch, but also a spin in turn one way forward, even the non-return devices also vary by design.

(That is not 360 degree rotation) one-way on the chain.
Self-winding mechanism for one-way
The so-called one-way and two-way on the chain difference is whether the automatic plate has a clockwise and counterclockwise rotation of gear to promote the chain, if the chain is only one direction, another direction of rotation, the gear must be slippage, that is, on the one-way chain. Automatic name suggests is a one-way automatic panel can be only one direction on the chain, that is, some rounds from automatic transmission to Tai continuous reel, but the other direction can not be on the chain, so to be idle gear, or through a clutch gear as an intermediary, to sever relations with all automatic transmission between the drive wheel, which is a simple one-way on the chain principle, and we often say that the efficiency of one-way Automatic limited, that is, half the time because of the automatic disk are in fact In the idling of the reason.

The shape and design of automatic plate
Today we can see a lot of automatic watch in the automatic drive to do different designs, we are curious whether the shape will have different impact on the chain efficiency? In fact, the shape of the automatic plate is not much impact on the chain, but added that with the weight of the material the way, many brands like to use 21K gold plate material to create the automatic block, which is helpful on the chain efficiency, but more emphasis on aesthetics, or, for the thin sheet, the entire precious metals to create an automatic disk but will become a burden, so they are mostly produced by automatic plate outer edge of the practice of a noble metal to improve the efficiency of the chain.
Automatic plate bearing the type
In addition, automatic disk position in the movement of the central axis, in order to reduce the rotation of 360 degrees and may create friction, must have a device called a bearing axis and automatic disk as undertake media, the media can help Automatic disk spin on the refining effect, and therefore can have different designs, it is left above the design of ruby bearings, on both sides of the axis of the ruby; To the right was the design of ball bearings (both sides of the axis Splitting two round ball), but there are five or seven ball bearing design, but also the design of ceramic materials, and many brands like to use this advanced design.
