The main spring winder, also known as the mainspring winder or mainspring winder tool, is a tool used in watchmaking to wind and unwind the mainspring of a mechanical watch. It is an essential tool for professional watchmakers and watch repairers, enabling them to efficiently and accurately wind and unwind the mainspring, facilitating the maintenance and repair of mechanical watches.

The mainspring winder consists of a handle or clamp and a set of interchangeable tips or columns of various sizes to accommodate different watch movements. The tips are designed to fit the main barrel arbor of the mainspring and provide a secure grip for winding and unwinding the mainspring.

The use of the mainspring winder requires precision and skill in handling to ensure proper winding or unwinding of the mainspring. It is a delicate process that requires experience and expertise, as improper handling of the mainspring can lead to damage to the watch movement or even injury to the watchmaker.

The mainspring winder ensures proper winding for optimal power transmission and maintains the accuracy of time measurement in the watch.
