AP Clocks

Welcome to AP Clocks Timeless design. Brilliant color. Handmade with care. We specialize in the AURORA and PRISMA™—vintage color-shifting clocks first made in the 1970s. These iconic timepieces use polarized light and special materials to create vivid, ever-changing colors. Originally developed by Kirsch-Hamilton, the AURORA was even recognized by the Museum of Modern Art. Later models like the PRISMA™ and SPECTRA™ followed, building a loyal following. AP Clocks proudly continues the legacy today. We manufacture new AURORA clocks and repair both AURORA and PRISMA™ models. Each one is carefully handcrafted in the U.S. Founded in 2021, AP Clocks brings over 7 years of hands-on experience working with these rare and beautiful clocks.
