Abstract
A watch (2) including an analogue display (6), at least one electroluminescent source (8a, 8c), and a light guide (30) located above said at least one electroluminescent source (8). The analogue display includes a first luminous hand (10) and a second luminous hand (12) pivotally arranged around the same axis of rotation (14); the elongate bodies (16, 17) of the first and second luminous hands extend respectively in a first general median plane (20) and a second general median plane (22) located above the first general median plane; the first luminous hand is fastened to a pipe (26) aligned with the axis of rotation and can be rotated by the movement. The light guide is carried by the first hand (10) and is rotationally attached thereto.
Claims13
A watch comprising a movement, an analogue display, at least one electroluminescent source and a light guide located above said at least one electroluminescent source;
- the analogue display comprising a first luminous hand and a second luminous hand, which are pivotally arranged around the same axis of rotation and formed respectively by a first elongate body and by a second elongate body that each comprise a transparent lower structure in which light from said at least one electroluminescent source can propagate after propagating in the light guide, the first elongate body comprising a circular central part surrounding a pipe aligned on the axis of rotation and fastened to this pipe, the first elongate body extending in a first general median plane and the second elongate body extending in a second general median plane located above the first general median plane relative to the movement;
- wherein the light guide is carried by a pivoting assembly formed by the first hand and by the pipe and rotationally attached to this assembly, the light guide having a lower annular part that surrounds said pipe and is located between said at least one electroluminescent source and the first general median plane, and an upper part that axially extends the lower annular part, outside the first luminous hand when viewed axially in the first general median plane, at least to the first general median plane.
