This bolt auricular needle spring shaft is a functional watch component designed for repair and reassembly tasks. Available in a set of six precise millimetre measurements, it serves as a direct replacement part for timepieces requiring this specific type of shaft. The availability in multiple sizes – 21mm, 22mm, 23mm, 24mm, 25mm, and 26mm – increases its utility across different watch models and movement types. It addresses the need for an exact component in scenarios where original parts are lost or damaged during servicing.
Features and Construction

As a specialised watch part, its primary feature is its dimensional specificity. It is not a generic component but a precise bolt auricular needle spring shaft.
Material and Build
The source text does not specify the material from which this shaft is manufactured. Therefore, no claims can be made regarding its metallic composition, plating, or surface treatment. Its designation as a "bolt auricular needle spring shaft" indicates its mechanical function within a watch's assembly.
Size and Practical Fit
The product's key specification is its availability in six distinct lengths: 21mm, 22mm, 23mm, 24mm, 25mm, and 26mm. This range accommodates various watch case dimensions and movement layouts. Users must select the size that matches the requirements of the specific watch being repaired, as a mismatched length could prevent proper assembly or function.
Uses and Placement

This component has a clearly defined role within the watch repair and horology fields.
Event or Professional Use
For professional watchmakers and repair technicians, this part serves as a necessary inventory item. It allows for the completion of service jobs where the original shaft is worn, broken, or missing. Having a selection of sizes on hand streamlines the repair process for a workshop dealing with multiple watch brands and models that utilise this style of component.
Everyday Home Use
For hobbyists and enthusiasts attempting DIY watch repairs, this shaft provides the opportunity to restore a non-functional timepiece. It is suitable for projects involving older watches where original manufacturer parts may be obsolete or difficult to source. Care must be taken to ensure the correct size is used and that the user possesses the necessary fine tools and skills for the installation.
Benefits and Buying Value

The value of this product lies in its specificity and function rather than aesthetic qualities.
Reuse and Low Maintenance
As a replacement part, its primary benefit is enabling the reuse and continued operation of a watch that would otherwise remain unusable. The component itself requires no maintenance; its value is realised through its correct installation into the timepiece. This contributes to a more sustainable approach by extending the life of an existing item rather than necessitating a full replacement.
Why Choose This Product
This product is chosen for its precise match to a technical need. The range of six sizes offers a practical solution for individuals or workshops that encounter various watch models. It provides a straightforward way to obtain a component that is often not sold individually by watch manufacturers. The selection allows buyers to purchase the exact size required or to stock multiple sizes for broader repair capability.
