🕰 Clocks go forward in the UK tonight 🕰

Here’s an elaborate timepiece from the collection – a 19th-century rolling-ball clock made in London✨

When the ball reaches the end of each run, it hits a release lever causing the tray to tilt, and the ball rolls back along the track. This process repeats every 30 seconds.
