Watch Bolt Auricular Needle Spring Shafts for Component Replacement and Repair

This product is a specific watch accessory part: an auricular needle spring shaft, often referred to as a watch bolt component. It is designed as a replacement part for use within the internal mechanisms of watches, where such shafts are integral to function. The key practical advantage is the availability across a defined range of sizes – 21mm, 22mm, 23mm, 24mm, 25mm, and 26mm – allowing users to match the exact dimension required for their repair job. Constructed from what the source describes as an environmental protection material, it is supplied as a single component per order, forming part of a larger inventory system.

Features and Construction

The product’s specifications are centred on its role as a precise mechanical component. The source provides concrete measurements but limited detail on material properties beyond a general classification.

Material and Build

The shaft is made from an environmental protection material. The source text does not elaborate on the specific polymer, alloy, or composite used, nor does it provide data on tensile strength, corrosion resistance, or durability. Therefore, the primary known characteristic is its classification under this material category. It is presented as a single, finished component ready for installation.

Size and Practical Fit

Size is the most detailed specification. The shaft is available in six discrete lengths: 21mm, 22mm, 23mm, 24mm, 25mm, and 26mm. This range caters to different watch models and movement sizes. The user must identify the required length from the original part or watch specifications to ensure a correct fit. No diameter or thread specifications are provided in the source, so compatibility relies on the length being the primary matching criterion.

Uses and Placement

This component has a clear, specialised application within watch maintenance and repair.

Event or Professional Use

For professional watchmakers, jewellers, or repair technicians, this part serves as a consumable replacement item. The availability of multiple sizes in bulk packaging (referenced as 200,000 boxes) suggests it is suitable for workshop inventory. It allows for the quick resolution of specific failures where the auricular needle spring shaft is broken, worn, or lost, minimising downtime for a watch repair service.

Everyday Home Use

For hobbyists or individuals attempting DIY watch repair, this component provides the exact part needed for certain internal fixes. Its value lies in enabling repairs that would otherwise be impossible without sourcing an identical component. Users require basic watch repair tools and knowledge to safely disassemble the watch, remove the old shaft, and install this new one correctly.

Benefits and Buying Value

The product’s value is derived from its specificity and the practical problem it solves.

Reuse and Low Maintenance

As a replacement part, its core function is to restore a watch to working order, extending the life of the timepiece and avoiding the need for a completely new movement or watch. The environmental protection material designation may imply certain production standards, but without specific data, the main maintenance benefit is simply the successful completion of the repair.

Why Choose This Product

You would choose this specific auricular needle spring shaft if you have identified this exact component as faulty and know the required length from 21mm to 26mm. Its value is in providing a direct, size-matched replacement. The alternative is often being unable to complete the repair. The product listing provides the necessary sizes clearly, which is the critical information for purchase.
