Features and Construction

This product provides a practical solution for watch repair with its straightforward specification and material choice.
Material and Build
The shafts are constructed from an environmental protection material. This specification indicates a material choice made with certain environmental considerations, though its precise technical properties for longevity and resistance to wear in a watch mechanism are not detailed in the source text. The part is manufactured to function as a direct mechanical replacement.
Size and Practical Fit
The key feature is the availability of six distinct sizes: 21mm, 22mm, 23mm, 24mm, 25mm, and 26mm. This range covers a spectrum of common sizes needed for different watch models and movements. Having this selection allows the user to match the shaft precisely to the dimensions of the original part they are replacing, which is critical for a successful repair and proper function of the watch.
Uses and Placement

These components have a specific role in watch servicing and are not general-purpose items.
Event or Professional Use
For professional watchmakers and repair technicians, this product serves as a consumable part for servicing customer timepieces. The large quantity of 200,000 pieces per box makes it suitable for a busy workshop or a parts supplier, ensuring a high-volume stock of a commonly needed component. It supports efficient workflow by reducing the time spent sourcing individual sizes.
Everyday Home Use
For the dedicated watch enthusiast or hobbyist engaged in DIY watch repair, this pack offers a cost-effective way to acquire a vital component. It is particularly useful for those who repair multiple watches or who want to have spare parts available for future projects. The user must have the necessary skill and tools to safely install the shaft within the watch movement.
Benefits and Buying Value

The value of this product lies in its practicality for a specific repair task.
Reuse and Low Maintenance
As a replacement part, its primary benefit is enabling the reuse and restoration of a watch that might otherwise be discarded due to a single broken component.

Why Choose This Product
The decision to choose this product hinges on the need for a specific watch repair part. Its main advantages are the clear size specification, which ensures compatibility, and the material description.
