The Mahogany Block Clock was originally designed by George Nelson in the 1940s to 1950s, our version of the iconic Block Clock looks equally as stunning now and contemporary as when it was first conceived. This great looking clock features wooden mahogany rectangular "bars" on stems; a beige face and the classic Nelson hour and minute hands in black. The Mahogany Block Clock measures 13-1/2" in diameter and operates on one AA battery (not included).
