This spring bar and pin punch point is a workshop-grade consumable designed for professional watchmakers, jewellers and serious enthusiasts who service mechanical and quartz watches. Made of hardened steel, it delivers the consistency, repeatability and finish required when working on luxury watches from Rolex, Omega or Seiko without leaving any residue on the case-back, the crystal or the bracelet. Whether you are restoring a scratched mineral crystal, cleaning a silver bracelet, lubricating an escapement or fitting hands on a quartz calibre, this watchmaker tool is built to deliver a clean and controlled result across thousands of service cycles. It complements the rest of a professional bench, alongside calipers measured in mm, torque wrenches calibrated in Nm and tools hardened to 55 to 58 HRC.
Product overview
The spring bar and pin punch point combines a carefully tuned formulation and an ergonomic format with a working profile designed for the exact geometry of modern watch components. Its key feature is the driving out spring bars and pins from watch bracelets, which translates into less effort at the bench and more control on the workpiece. Watchmakers appreciate how the product behaves during long sessions on the bench, while collectors value the reassurance of a workshop reference that will not damage a precious case-back or bezel. It is suitable for service work on most quartz and automatic watches with a case diameter typical of the 28 mm to 48 mm range that dominates the contemporary market.

When to use it
Reach for this spring bar and pin punch point whenever a routine intervention can only be carried out cleanly with a dedicated workshop reference. An improvised household product, a worn cloth or a generic oil will eventually mark the case-back, leave residue under a screw-back gasket or damage a delicate finish. Typical situations include a hairline scratch on a mineral or acrylic crystal, oxidation on a silver or gold bracelet, a dry pivot on a clock or wristwatch movement, and the fitting of new hands after a battery replacement. The product is also valuable during periodic inspection, when you need to refresh the appearance of a watch case and bracelet before showing the piece to a client, without going through a full polish that would alter the original bevels.
How to use it
- Place the watch on a soft mat or holder, dial down where appropriate, to protect the crystal during the operation.
- Inspect the area of work to identify the case-back type, a screw-back, a snap-on cover or a four-screw plate, and prepare the matching tools.
- Apply the product or position the working tip of the watchmaker tool firmly against the surface, keeping the axis perpendicular to the case.
- Work in small, controlled passes, with a torque typically no greater than 0.4 Nm on delicate closures, until the desired result is reached.
- Wipe the surface with a clean lint-free cloth to remove any residue from the case-back, the bracelet links or the crystal.
- Perform the intended task (polishing, cleaning, oiling, hand setting, movement check) without touching the dial.
- Refit any cover, ensuring threads or clips align, then apply moderate finger pressure to seat the screw-back or press-fit case-back.
Quality and origin
Quality control on this product follows the standards expected by professional Swiss watchmaking workshops. Materials and active ingredients are selected for their stability, the working profile is inspected for consistency, and every item is checked for fit and finish before shipping. The brand Bergeon is referenced repeatedly in this catalogue because it defines the benchmark in horology tooling; even when the reference is not a Bergeon item, the chemistry, the geometry and the tolerances are designed to be compatible with parts and procedures established by Bergeon, Rolex and Omega service manuals.
Frequently asked questions
Can I use this spring bar and pin punch point on a Rolex screw-back case?
Yes, provided the working profile matches the case-back engagement. Reference manuals from Rolex recommend a torque below 0.4 Nm when seating a screw-back, which this product allows by hand pressure alone.
Is the product safe for quartz movements from Seiko or Omega?
Yes. It is formulated or shaped to minimise the risk of contamination or static discharge on quartz modules from Seiko or Omega and is compatible with workshop environments where tools hardened to 55 to 58 HRC are used routinely.
How do I maintain a watchmaker tool of this type?
Wipe or close the product after each session and keep it away from heat sources and direct sunlight. Avoid solvents on plastic packaging. Store the watchmaker tool in a closed drawer or cabinet to protect it from dust that could be transferred to a watch case-back during the next service.
