Step into a master watchmaker's workshop. Assemble hundreds of microscopic parts under a loupe, tune the escapement until it sings, and build a vault of mechanical marvels.
A tiny gear train, live in your browser. Drag any gear to wind the movement, then nudge the regulator until the rate lands within tolerance.
At your wooden workbench, under a magnifying lens, use tweezers and screwdrivers to seat gears, bridges, escape wheels and balance springs.
Test builds live. Follow energy through the gear train, hear the escapement tick, and fine-tune your regulator for true accuracy.
Collect and display marvels, from 18th-century pocket watch movements to multi-axis tourbillons and moon-phase calendars.
Lay your device flat and your desk becomes a skeleton clock, all polished steel and mesmerizing gear choreography.
⚙️ We are a small crew of watch lovers and app makers who fell for the quiet drama of a ticking movement, and wanted everyone to be able to hold one.
🔧 Our mission is simple: bring the patience, precision and beauty of the watchmaker's bench to your screen, with no clutter and no rush.
⏳ With Chronos 1790 you assemble calibers piece by piece, tune real escapement behavior, and curate a vault of historic and modern marvels, even as a desk clock.
🕰️ Master the gears, and time becomes something you craft.
