積家，非常精細，18k紅金腕錶，配中心秒針，月相，日曆，雙動力儲存及六份一秒顯示，"Duomètre à Quantième Lunaire"，型號600.2.24.S，2012年製

A true masterpiece of micromechanics, the Duomètre Quantième Lunaire features two independent power reserves, one of which, in this case, is devoted solely to precise time measurement while the other takes care of the functional displays. Associated with the "Dual-Wing" concept, the zero/reset system for the seconds and the jumping stop seconds ensures accuracy to the nearest 1/6th second when setting the timepiece.
