The balance wheel is secured in place by a black PVD coated bridge at 6 o'clock. The generous proportions of the balance wheel (10.15mm in diameter) makes it less subject to disturbances and thus more accurate.
The micro-rotor is located to the top left of the movement, while the main-spring barrel is located to the right side for a symmetrical design.
