MOC Mechanical Clock & Kinetic Gear STEM Building Block Sets (Parts Kit + Digital Manual)

Electric Mechanical Clock — 302 building-block pieces, comes with an AA battery box and an "M" motor. Batteries are not included; you will need to provide your own. The assembly instructions are provided as a digital PDF step-by-step guide — after you receive your parts kit, please contact our customer service to obtain the instructions. (Please do not order if this is a concern.)

Note on parts: Different production batches may have slight color differences on certain pieces, but pieces of the same specification still assemble together perfectly. Parts are manually packed, so occasionally pieces may be missing — if so, please contact customer service for a free replacement.

Discover the fascinating world of horology and kinetic engineering with our MOC Mechanical Clock & Precision Gear STEM Building Block Sets.
