It's all about the 9’s with this big, colorful time-piece! So many ways to represent quantity: with arithmetic, with repeated decimals, with radicals, even with factorials. They're all here.

This clock was made with the classroom in mind:

  • A full 12 inches across for visibility from the back of the room.
  • Giclee print face with a bright, glossy finish.
  • American-made, quartz movement (accurate to 2-minutes/year) backed by a 5-year warranty.
  • Silent sweep second hand, so no irritating tick-tock.
  • Birch-laminate clock body with solid-pine frame back for durability.

This clock has metal hands held to the movement by brass fittings. The second hand can optionally be replaced by a solid brass cap-nut (included). A brass, one-step hanger is included for easy mounting. Requires one AA battery (not included).

All Platonic Realms clocks are assembled in Virginia from only the best American-made parts and materials. Brighten up your room with this colorful, educational, and reliable wall clock.
