由零開始 專利歸零裝置

專利歸零裝置為朗格所獨有,佩戴者可透過這項便利的功能快速且精準地設定時間。當拉出錶冠後,機芯便會掣停,而秒針亦會歸零,令分針與分鐘刻度對齊,然後按照鳴響報時準時重新啟動腕錶,這使腕錶同步更為容易。

歸零裝置

Display: Convenient time-setting. The zero-reset mechanism. Under a transparent representation of the RICHARD LANGE JUMPING SECONDS the zero-reset mechanism is shown and correctly positioned. After removal of the watch outlines, the operation of the mechanism is shown several times from different perspectives. The zero-reset hammer strikes the heart cam and drives it, together with the seconds hand, to the zero position. The mechanism finishes by turning to the rear-side view. Individual components are named.

此裝置由複雜槓桿系統組成,將歸零槓桿壓向心形凸輪。秒針連接至心形凸輪旋轉的同一心軸上。當心形凸輪透過歸零槓桿轉動至原來位置,秒針亦會跳回零位。再次將錶冠按回原位,即可重新啟動機芯及其秒針。

 

這個裝置的改良版本結合更複雜的設計,1815 TOURBILLON便是一例,不同的是,陀飛輪必須停動,擺輪則不在此限。
