In the past few years, we have covered plenty of unique clocks here. The Seiko QUF 107G Double Articulated Pendulum Clock is also worth a look. It is a rare clock with an electromagnetic base that keeps the pendulum moving. This clock has a 3-piece design. You can assemble it pretty fast.
These Seiko pendulum clocks were made in various styles. They are rare but you can still find them on sites such as eBay.
