The ROKR Pendulum Clock is a highly popular line of DIY 3D wooden mechanical puzzles manufactured by Robotime, which allow you to assemble a functioning clock without glue. Depending on whether you want a purely mechanical spring-driven machine or a practical timepiece that keeps real-time for days, ROKR offers a few distinct variations:
Purely Mechanical Engine: It relies entirely on a mechanical spring, gravity-swing pendulum, and precise anchor escapement without needing any batteries.
Limited Run Time: Once fully wound, it ticks and runs for about 3 to 4 hours, meaning it serves more as an engineering showpiece than a permanent wall clock.
Build Specs: Contains 166 pre-cut plywood pieces with an estimated assembly time of roughly 5 to 6 hours.
