Beschreibung
Zusammenfassung:	A temperature control device for a timepiece, includes a first light-transmitting portion, defining with a second adjacent portion an intermediate chamber of variable dimensions according to the temperature of the first portion, the first portion includes first microlouvers according to a first spatial distribution, the second portion includes second microlouvers according to a second spatial distribution and substantially facing the first microlouvers, to superimpose partially or totally in certain relative positions between the first portion and the second portion, in order to vary the transmission and/or the reflection of the incident light on the first portion between a maximum and a minimum.
