Rhythm “Small World Serena S” Musical Motion Decorative Pendulum Wall Clock from Japan - 4MN549RH23

This clock came from Rhythm USA's personal collection. When Rhythm USA dissolved at the beginning of 2025, we were lucky to have come into possession of the majority of the clocks in their Atlanta office and workshop. This includes everything from refurbished models, display pieces, samples, and even some off-the-wall prototypes. Over the course of the next few years, we will be sorting through our vast collection of Rhythm USA's personal timepieces and offering them to you at a great price. To honor Rhythm's legacy and to mark these timepieces as true collectibles, the back side of each clock will be tagged with a commemorative sticker. Own a piece of history today, and be sure to check back in the future for more timepieces from Rhythm USA's collection!

Known as “Small World Serena S” in the Japanese market, this model was imported by Rhythm USA. The Swarovski crystals on the pendulum are typically a bright blue, so I believe that this may have actually been a prototype or a sample of something they were looking into releasing outside of Japan.

Since this clock was produced for the Japanese market, it has a radio-controlled movement and only works on Japan’s radio waves. So, the time will need to be set manually by pressing and holding the buttons on the back. Click here for a video tutorial.
