This is a table clock made by Rhythm Clock, which manufactures Citizen clocks for the domestic market. It appears to be a Citizen-branded clock, without a doubt. It seems to be quite old, but it's in beautiful condition. The gray marble gives it a modern feel without being overly heavy. To start the pendulum at the bottom, turn on the switch on the lower back. Size: Maximum width 20.5 x depth 8 x height 25 cm It runs on two AA batteries, but please note that they will not be included when shipped. It's made of marble, so it weighs about 3kg and is quite heavy. Instant purchase is welcome! If you would like to combine shipping with other items, please request a combined purchase.
