    • Device for detecting and synchronising the position of at least one first wheel (16) of a timepiece mechanism (1) for an electronic analogue watch, wherein this first wheel (16) extends in one plane, the detection and synchronisation device (30) comprises at least one light source (32) emitting a light beam (34) and at least one light detection system (36), and this detection and synchronisation device is characterised in that a first light-reflecting element (40) projects from one of the upper or lower surfaces of the first wheel (16) of the timepiece mechanism (1), wherein the light source (32) and the light detection system (36) are arranged so that in a determined position of the first wheel (16) of the timepiece mechanism (1), the light beam (34) emitted by the light source (32) is reflected by the first reflective element (40) in the direction of the light detection system (36).
    • 用于检测和同步用于电子模拟手表的钟表机构(1)的至少一个第一轮(16)的位置的装置,其中该第一轮(16)在一个平面中延伸,所述检测和同步装置(30)包括 发射光束(34)的至少一个光源(32)和至少一个光检测系统(36),并且该检测和同步装置的特征在于,第一光反射元件(40)从 钟表机构(1)的第一轮(16)的上表面或下表面,其中光源(32)和光检测系统(36)被布置成使得在第一轮(16)的确定位置 钟表机构(1),由光源(32)发射的光束(34)被第一反射元件(40)沿光检测系统(36)的方向反射。
