Mechanical Watch Movement 3D Teardown

A single-file interactive 3D mechanical watch built with Three.js. Beneath the gold case, crystal, dial, and hands lies the movement you never normally see: the mainspring barrel, gear train, balance wheel and hairspring, escape wheel and pallet fork, and the red jewel bearings. The balance wheel swings, the gears turn, and the second hand ticks. Parts can be exploded apart in layers with name labels. Suited to horology education, precision mechanics explainers, and product showcases.
