Definition

1. Adjective:
   • Designed to operate without manual winding: Describes a mechanism, typically in a watch or clock, that winds itself automatically, usually through the natural motion of the wearer's arm or another power source, eliminating the need for manual winding.

Usage

• The term "self-winding" is used attributively, almost always before a noun, to describe the type of mechanism or the device that possesses it.
• It is a compound adjective formed from "self-" and "winding."

Examples

• Adjective:
  • He prefers a self-winding watch because he never remembers to wind it manually.
