The octagon frame on this 18" diameter clock is made from precision machined sections that easily assemble with glue, dowels, and strap clamping included in the kit. Choose either a gold or silver mirrored acrylic dial which is beautifully laser cut through at the hour and minute markers. We recommend covering the masoniteback panel with paint, fabric, or Suede-Tex (sold separately) which will then show through the openings. Dials also sold separately (see below).
