replica watches uk brand, regardless of price or quality, as well as hedge the ability, really good. The industry recognized. Many fans of the watch, especially like the big labor I have to maintain a lot of money and labor, and remember some customers are very stubborn, that this is the top gold watch, do not need maintenance, it should go all the way ... ... replica watches's constant-motion device was invented in 1931 and equipped with a half-moon automatic tattoo that swings with the wearer's wrist to sway around the central wheel. This device has been tightening the winding for the watch to provide a sustained and stable power source. Rolex is currently used in the constant-motion chain device is a constant-wheel drive on the chain design. The wheel is the essence of this self-winding design, the figure is swiss replica watches's Teflon red wheel. ------------------------------ To explore the watch knowledge, three mountain watch industry WeChat: weiweimL360 (← long press can be copied) ------------------------------ A commutator wheel is divided into double layers, the red arrows refer to the inner wheels, and the blue arrows refer to the outer wheels. There are pawls inside the outer wheel, like the manual movement of the inside of the pawl only move the gear in one direction, the other direction is not OK. Through this design, when the inner wheel and outer wheel together, the outer wheel by the power counterclockwise rotation, inside the inner wheel will be stuck, and then the inner wheel will follow the outer wheel with the rotation. If the outer wheel is rotated clockwise, the inner wheels will slip and the inner wheels will not rotate with the outer wheels. It is worth noting that the direction of the pawl inside the two reversing wheels is not the same, so the direction of the two commutator slips and the rotation is exactly the opposite We return to the Rolex 3135 movement, analysis of the entire process of self-winding movement. The first step in the blue arrow refers to the automatic rotation, clockwise counterclockwise The second step of the red arrow refers to the terher with the automatic rotation, the direction is also clockwise counterclockwise The third step is divided into two cases (1) automatic Tuo clockwise rotation, driving the green arrows referred to the reversing wheel counterclockwise rotation, then the inside of the inner wheel will be stuck, and then the inner wheel will follow the outer wheel with the rotation. The rotation of the inner wheel will cause the white arrows to refer to the place also counterclockwise rotation, and then drive the black arrow pointed to the automatic first round clockwise rotation to the barrel on the chain, so that the winding tightening, storage of energy. At this point, the green wheel refers to the first reversing wheel of the outer wheel will lead the purple arrow refers to the second reversing wheel, but because of the second reversing wheel inside the pawl and the first commutation Round the inside of the installation in the opposite order, so the second wheel inside the inner wheel will slip. (2) when the automatic rotation of the counterclockwise rotation, driven by the green arrows referred to the reversing wheel clockwise rotation, then the inside of the inner wheel will slip, at the same time, the green arrow pointed to the first wheel It will drive the purple arrow refers to the second wheel of the wheel counterclockwise rotation, then the inside of the inner wheel will be stuck, and then the inner wheel will follow the outer wheel with the rotation. The rotation of the inner wheel will cause the yellow arrow to refer to the place also counterclockwise rotation, and then drive the black arrow pointed to the automatic first round clockwise rotation to the winding plate on the chain, so that the winding tightening, storage of energy. Through the above analysis, we can clearly find that the red arrow refers to this part is very important, plays a role in the opening, half-moon automatically through the transfer of energy to the back of the wheel. And here, that is, Rolex movement is one of the most vulnerable to damage. The reason is that Rolex is here using a single pendulum. If the long-term use. Smooth oil dry, increase the central axis friction offset, coupled with automatic Tuo only one central shaft support, by the vibration will lead to automatic Tuo Sassafras, damage the movement. Wipe edge of the impact on the chain efficiency, while the wear and tear coating, affecting the movement beautiful, even worse, debris scattered in the movement inside, affecting the time to go. On the map where the red arrow can be seen half of the pendulum Tuo and Tuo Tuo between the subtle gap. These gaps cause the entire pendulum to shift in rotation, and thus severely scratch the movement (blue arrow means). Rolex this design has been criticized by everyone. In 1948 ETERNA used five miniature balls, this initiative to solve the pendulum of the support of the problem, to prevent long-term use of the wear and impact caused by automatic Tuo to the movement splint. Later, this design to set up Chi-year logo, still in use today. But because of the patent issue, Rolex has not used the ball design. Even after the expiration of the patent, Rolex did not use. Currently Cal.4030, Cal.4130, Cal.9001, Cal.4160 are used for ball bearings, the next generation Rolex base movement Cal.32 series has also been used. But the current Rolex use of the main movement of the Department of 31 or the same, using a single Tuo axis support. Rolex's problem is a design flaw, we ordinary consumers can not solve. In order to avoid the use of watches in the process must bear in mind three points: the first does not wear a watch for intense sports, such as basketball, football, diving, watch tennis, badminton, golf and so on. The second every 2 to 3 years will be the watch to the professional maintenance agencies to check, every 4 to 5 years will be a comprehensive maintenance. The third time once the feeling of movement Tuo Tuo rotation difficult. Case inside the abnormal sound. Debris, screws and other parts fall, please immediately sent to the professional maintenance agencies overhaul.
