Setting up a watch winder? Pick your brand and movement to get the right TPD (turns per day) and rotation direction. Most automatics want 650 to 800 TPD, and if yours is not listed, 700 TPD bidirectional is a safe default for almost any movement.

Frequently asked
What is TPD on a watch winder?
TPD means turns per day, the number of full rotations a winder gives a watch in 24 hours to keep its automatic movement wound. Most modern automatics need between 650 and 800 TPD; too few leaves it underwound, while a quality winder simply pauses once fully wound so more is not harmful.
What TPD should I set for a Rolex?
Most modern Rolex calibres (3135, 32xx) are happy at about 650 TPD, bidirectional. If your winder only does set increments, 650 to 750 bidirectional is safe.
What direction should my winder turn?
Bidirectional suits the vast majority of automatics and is the safe default. A few movements (some Miyota 8200-series) wind more efficiently clockwise, but bidirectional still works for them.
I cannot find my exact movement — what do I use?
Use 700 TPD, bidirectional. That sits in the safe middle of the common 650 to 800 range and works for almost any automatic. A good winder stops turning once the mainspring is full, so a slightly high setting will not overwind it.
