Carl F. Bucherer earned manufacture status in 2008 with the launch of its first in-house movement, the automatic CFB A1000. This year the company unveiled its second in-house movement, CFB A2000, which makes its debut in this week’s Watch to Watch, the new Carl F. Bucherer Manero Peripheral chronometer watch. The name refers to the peripheral rotor that is the hallmark of the movement’s automatic winding system. (The A1000 also featured a peripheral rotor. CFB says it is the first watch manufacturer to put a peripheral-rotor movement into serial production.)
The A2000 has a free sprung balance; fine adjustment is performed by means of pivoting masselottes – small weights that sit on the four balance arms. The balance oscillates at 28,800 vph, or 4 Hz, compared to the CFB A1000’s 3-Hz frequency – which helps to ensure a more precise rate. The watch has a power reserve of 55 hours. The movement’s bridges and balance cocks are decorated with Geneva waves. The A2000 series will serve as the firm’s base automatic movement. It will be incorporated into new models and can be modified with complications.
