The principle of the flat end curve, placed on the same level as the balance-spring, compensates for off-centering and facilitates its fastening. Triple pare-chute shock-absorbing system* reduces potential disturbances due to impacts to an absolute minimum and protects the balance-spring pivots. Exclusive three-dimensional moon-phase indication* by means of a platinum and blued steel sphere revolving on its axis and accurate to within one day every 122 years. |
