ABSTRACT:
An illumination device (7, 23) for a wristwatch (1), having a completely self-contained power source (15) and illuminating lamp (17, 29) which is carried on the watchband (6). A flexible wall (21, 31) permits contact between lamp terminals (20, 35) and battery terminals to close the circuit when the device is manually actuated. An overhanging portion (8, 26) extends beyond the attachment (28) of the band to the wristwatch, so that the lamp (17, 29) may illuminate the face (4) of the wristwatch.
