HOROLOGY LAB – An application featuring ten watch models with diverse mechanisms. Users can browse, filter, and select models from the library; rotate, zoom, detach straps, use X-ray views, and explode assemblies to examine structures; view component labels that track positions and auto-align during rotation; select individual parts to view in isolation or read descriptions; disassemble and reassemble in the correct order; drag detached assemblies, undo actions, or reset positions; experiment with materials, adjust cross-sections, and compare surfaces on the same part; operate movements by winding, spinning the automatic rotor, or powering on (depending on the model); adjust speed, pause, and trace energy flow step-by-step; compare two movements with independent power sources and optional synchronization; explore functions such as chronographs, dual time zones, date displays, moon phases, power reserves, and tourbillons; adjust battery, lighting, or oscillation settings on supported models; and view time synced to the device. In the design workshop, users can select components, change materials or finishes, swap in compatible parts from other models, confirm or undo selections, reassemble, name, save, edit, and delete designs. Data is stored locally on the device or kept only for the current session if browser storage is restricted. Main pages are linked via a bottom navigation bar (which hides on secondary screens); the app supports touch, mouse, and keyboard inputs, as well as reduced motion settings. It operates offline; simulations are for observation purposes and do not replace precise measurements or manufacturing verification.
