Notes
1953-1955
patented double-excenter winding with jewelled rollers (for low height)
jewel-bearing rotor
An intermediate wheel between minute pinion and the rest of the train allows big balance and low profile without reducing the sturdiness (cf. Cyma 10 Pleiade).
Moreover this layout allows to place the seconds wheel either in the center or for a sub second, without further modifications (details cf. Cyma 488.2).
first few samples with hidden balance cock (Fig.1-2)
early samples partially or completely pink gold plated (Fig.1-3)
late samples with new rotor lock and ring balance (Fig.6)
