The unique shape, rarity and high price all make RICHARD MILLE have a high degree of attention in the watch market, but of course, the brand’s creativity and technology are the foundation of its success. For example, the new RM 30-01 clutch rotor self-winding watch that debuted this year is based on the principle of ease of use, and then shows the novelty of complex machinery on the watch.

If you still remember, it is not the first time that the clutch rotor design has appeared on Richard Mille best cheap watches. This design has already been adopted on the RM 030 launched in 2011 and its RMAR1 movement— – When the mainspring drum is fully charged, the oscillating weight will disengage from the self-winding wheel train. It can be said that the RM 30-01 that debuted this time is further developed on this basis, but it is more complicated, and a super-large date display is also added. This design is also reminiscent of the RM 029 super-large date that was launched in the same year as the RM 030. Automatic watch. Therefore, RM 30-01 can be said to be a combination of the two, drawing on the experience of the previous work, and reinterpreting the hollow design to create a more refined and more balanced and harmonious effect visually.

The case of RM 30-01 continues Richard Mille’s classic barrel-shaped shape, and is ergonomically designed. It is hand-decorated with satin polishing, polishing and chamfering, etc., and has complex lines and geometric structures, making it the most advanced in the industry. One of the most difficult watch cases to develop and manufacture. The case also adopts a three-piece design, combining parts such as case, dial, movement, nitrile rubber O-ring, grade 5 titanium alloy spline screws and 316L stainless steel anti-wear washers.

This time a total of two material styles have been launched: one is made of 5N red gold for the bottom cover and bezel, with a middle case made of grade 5 titanium alloy; the other is made entirely of grade 5 titanium alloy. The movement and case are also fixed by spline screws made of grade 5 titanium alloy. The spline screws can better control the screw torque during the assembly process and are less prone to aging. Moreover, titanium alloy has excellent anti-allergic, anti-corrosion and impact resistance properties, and can reduce the weight of the watch body as much as possible, resulting in a high quality copy watches weight of only 96g including the strap.

There is a large three-hand in the center of the hollow dial; the power reserve display can be seen at the 9-12 o’clock position; the super-large date display window can be seen at the 4 position, which uses a semi-instantaneous jump display. The details of the RMAR2 movement can also be seen on it. The grade 5 titanium alloy bottom plate and bridge plate enhance the sense of perspective and depth through parallel stacked parts. styling. What’s more special is that the shape of each display window on the watch is not the same as the curve of the previous work, but adopts a diamond-shaped geometric structure, which adds dynamic vitality. The power reserve, winding and crown function selectors have also adopted a new layout and are embellished with different bright colors.

This watch is also equipped with a crown function selector, which is operated by a button at the 2 o’clock position of the case, and its principle is similar to that of a car gearbox. Just press the button to choose between three modes: time adjustment, date setting and winding function. The currently selected mode can be displayed above the large date window on the dial, “H” indicates the time adjustment, “W” indicates the winding function, and “D” indicates the date setting. fashion replica watches

The biggest feature of the RM 30-01 is the clutch-type oscillating weight. The RMAR2 movement it carries is more sophisticated than the previous one, and the power reserve is about 55 hours. Generally speaking, the winding of the pendulum will provide power for the movement, and the tension of the mainspring can reach the best state when the winding is fully wound. However, this mechanism is very prone to over-winding, resulting in excessive tension of the mainspring. The traditional solution is to use a sliding collar to loosen the mainspring to prevent the movement from being overwound, but this cannot avoid wear and tear. In the RMAR2 movement, when the power reserve reaches 55 hours, that is, when the chain is fully wound, the variable geometry oscillating weight of the movement will automatically separate from the winding mechanism to eliminate the tension of the mainspring after the chain is fully wound and also It can ensure that the movement runs under the most ideal and stable torque/power ratio of the mainspring drum. And when the power begins to decrease and falls below 40 hours, the rotor will automatically re-engage, allowing the barrel to be wound up again.

Like the crown function selector, there is also a special indicator on the dial to indicate the clutch engagement status. As long as you pay attention to the clutch engagement status indicator at 11 o’clock, you can know whether the pendulum is in the winding state (on) or disengaged state (off). buy replica watches

In addition, the RMAR2 movement is also equipped with a variable inertia free-sprung balance wheel, which can enhance the reliability of the watch when it is subjected to vibration and movement loading and unloading, thereby providing more accurate and long-term precise timing. At the same time, 4 adjustable small weights directly placed on the balance wheel replace the speed needle fine-tuning system, so as to adjust the inertia of the balance wheel more accurately and stably.

The movement is made of hand-polished grade 5 titanium alloy bottom plate and bridge plate, which are treated by wet sandblasting and gray plasma process, and the mainspring drum bridge plate is also treated with PVD coating. All kinds of fine decoration and treatment on the movement can be appreciated through the sapphire crystal bottom cover.
