OMTIME has six different designs of yoga-themed, wall clocks. We call them yoga clocks. The wooden timepieces are 16" in diameter, featuring a yoga design that is laser engraved. We also have vinyl clocks with different designs, including mandalas. They are 12" in diameter. What makes these clocks special is the designs of the clocks. The clocks have mandalas and eastern philosophy symbols. Each clock is designed for the mind and soul of its owner, and all of our clocks run on one AA battery.
