A timepiece comprises a display including a light emitting element. A detector detects ambient light around the timepiece and a switch is switchable into first and second operating modes. When the switch is in the first mode the light emitting element is illuminated at a first brightness level when the detected ambient light is below a predetermined level and the light emitting element is not illuminated when the detected ambient light is above the predetermined level. When the switch is in the second mode, the light emitting element is illuminated at a second brightness level which is greater than the first brightness level.
