Abstract

Pièce d'horlogerie comportant une boîte logeant un mouvement horloger (1) comprenant
une source d'énergie mécanique (12),
un mécanisme de comptage de la réserve de marche de la source d'énergie mécanique (12) comprenant notamment un mobile de comptage (16),
la pièce d'horlogerie comportant des premier et second organes transparents polarisés (4, 6), superposés et visibles depuis l'extérieur de la boîte, dont l'un au moins présente une liaison cinématique avec le mobile de comptage (16), de telle manière que l'orientation angulaire relative entre les premier et second organes transparents polarisés (4, 6) est fonction de la valeur de la réserve de marche à chaque instant.

Figure imgaf001
Timepiece comprising a box housing a watch movement (1) comprising
a source of mechanical energy (12),
a mechanism for counting the power reserve of the mechanical energy source (12) comprising in particular a counting wheel (16),
the timepiece comprising first and second polarized transparent members (4, 6) superposed and visible from the outside of the box, at least one of which has a kinematic link with the counting wheel (16), such that the relative angular orientation between the first and second polarized transparent members (4, 6) is a function of the value of the power reserve at each moment.
