Travel clocks were very popular in the old days as people didn't have any mobile phones to wake them up. They very often looked like cases that you opened to place them on your nightstand. Once closed, the clock was protected inside its case and could travel in a handbag, a suitcase...
It is made of plastic and metal.
This clock works very well although the alarm needle tends to move with the hour needles when you change the time (so it is better to turn the knob clockwise, it avoids this problem), and the alarm does not ring for a very long time (10 to 15 seconds maximum).
The last photo shows the user's guide.
The clock's case is in excellent condition. The cardboard box is in average condition.
Dimensions : 8 cm x 7.5 cm = 3.14" x 2.95"
Weight of the clock + its cardboard box (without protection and packaging): 142 g
