Richard Mille 稀有鈦金屬男裝手動上弦雙秒追針計時碼錶約2008年

The Richard Mille brand was launched in 2001, using innovative techniques inspired by Formula One racing and the aeronautical industry. Richard Mille watches utilize highly unique materials which are chosen for specific purposes to improve efficiency, comfort and reliability such as Alusic or carbon nanofiber. A decade after its inception, the company achieved a cult following amongst watch collectors because of this innovative approach to watchmaking. Richard Mille is one of the first watch brands to introduce the torque indicator function. It provides important information about the tension of the mainspring, which allows the optimization of the chronograph function of the movement - considered to be under tension at or below 53dNmm, excessive at 65dNmm. This information is useful for the user to decide if the watch is at optimum operating performance.
