Regulation, to the turn.

A microprocessor-governed gearbox winder. Turns per day, direction, and rest protocol — set precisely, held precisely.

The Mechanism

A gearbox, governed by firmware.

A stepper motor drives a two-stage precision gearbox; a planetary reduction drives the cup. The arrangement isolates the watch from torque spikes and lets turns-per-day be programmed in one-turn increments.

iDriveBrushless DC stepper + two-stage gearbox + planetary reduction
iiTurns per day650 to 1,950, set in single-turn increments
iiiDirectionClockwise, counter-clockwise, or bidirectional
ivRest protocolUser-defined wind/rest cycle, hours adjustable
vControlDedicated microcontroller on a shock-mounted board
viService lifeMotor runs at fraction of rated stress; measured in decades

By Comparison

Why gearbox design matters.

	Mass-market “programmable”	Orbita Programmable
Drive	Direct-drive, brushed motor	Stepper + two-stage gearbox
TPD	Fixed presets, approximate	650–1,950, single-turn steps
Direction	Usually one direction	CW, CCW, or bidirectional
Verification	Open-loop, no feedback	Revolution count vs elapsed time
Service life	18–24 months typical	Measured in decades
