Abstract

An electronic timepiece comprising a translucent member (6, 6b), which carries a solar cell (7); a support plate (5, 5b) which supports the translucent member (6, 6b); a base plate (9, 9b) which supports the support plate (5, 5b); and a case (1, 1b) within which the translucent member (6, 6b), solar cell (7), support plate (5, 5b) and base plate (9, 9b) are disposed characterised in that the base plate (9, 9b) engages the case (1, 1b); the support plate (5, 5b) is disposed in contact with the base plate (9, 9b); and resilient means (16, 16b, 16c, 16d) are interposed between the support plate (5, 5b) and the case (1, 1b), or means (17b, 17c, 17d) connected to the latter.
