To provide a device for measuring a horological component that allows the machining of the horological component to be optimized without slowing down or burdening in a method for manufacturing the horological component.SOLUTION: A device for measuring a horological component comprises a measurement cell 4, at least two optical systems, and a driver unit. The measurement cell comprises a measurement channel 6 filled with a liquid, and flat and parallel faces. Each optical system comprises a light emitter 21 suitable for emitting a light with a predefined wavelength so as to illuminate a horological component that is present and being displaced in the measurement zone in the measurement channel, and an optical sensor 22 associated with the light emitter to receive at least a part of the light emitted by the light emitter. The optical systems operate in different respective wavelengths. The driver unit drives the optical systems and processes digital data obtained from the optical systems. The driver unit is configured to implement calculations of at least one measurement of a horological component.SELECTED DRAWING: Figure 3 【課題】時計部品の製造方法において、速度低下や負担なくして、時計部品の機械加工を最適化可能にする時計部品の測定装置を提供する。【解決手段】時計部品の測定装置は、測定用セル４と、少なくとも２つの光学系と、駆動ユニットとを含む。測定用セルは、液体で充填された測定チャネル６と、平坦であり平行な面を含む。各光学系は、測定チャネルの測定区域内に存在し変位される時計部品を照明可能なように、所定の波長の光を発するのに適した発光体２１と、発光体が発する光の少なくとも一部を受けるための、発光体と関連付けられた光学センサ２２とを含む。光学系は、それぞれ異なる波長で作動する。駆動ユニットは、光学系を駆動し、光学系から得られたデジタルデータを処理する。駆動ユニットは、時計部品の少なくとも１つの寸法の計算を実施するよう構成される。【選択図】図３
