"Balance wheel" nghĩa là con lắc (đồng hồ).
Ví dụ
The caliber 9R01 is regulated by Grand Seiko's proprietary Spring Drive regulator, which uses a quartz crystal and a steadily rotating flywheel instead of a standard balance wheel to keep the time.
The manually wound movement holds a 55-hour power reserve and features an extra-large balance wheel, a traditional 18,000-vph balance frequency, a column wheel with horizontal coupling, a patented V-shaped chronograph bridge — all signature elements of vintage Minerva calibers, along with the hand-decorated Minerva arrow on the bridge.
Today, the Raymond Weil unveils a new timepiece (đồng hồ) driven by Calibre RW121. The Freelancer Calibre RW1212 features a 42 mm stainless steel dial (mặt đồng hồ bằng i-nốc) framed by a green satin chapter ring with silver indices, Clous de Paris in the centre and a seconds train on the outside. An open aperture at 6 o’clock gives a fascinating view into RW1212 Calibre movement, revealing the oscillating balance wheel, the pulsating hairspring and the vibrating pallet lever.
