Bergeon Swiss Tool for Screw-Down Watches

This strap and case-screw removal tool from the Bergeon (reference 7260) is a precision instrument designed for professional watchmakers and serious enthusiasts who service mechanical and quartz watches. Made from Swiss Delrin polymer with steel screwdrivers, it offers the dimensional accuracy, repeatability and surface finish required when working on luxury watches from Rolex, Omega or Seiko without leaving the slightest mark on the case-back, crystal or bracelet. Whether you are replacing a battery, fitting a new gasket, opening a screw-back case or removing the hands from a chronograph movement, this watchmaker tool is built to deliver consistent results across thousands of service cycles.

Overview

The strap and case-screw removal tool combines an ergonomic body with a working tip engineered for the exact geometry of modern watch components. Its key feature is the removes single and double screws on bracelets and case middles, gold/platinum/silver safe, which translates into less force at the wrist and more control at the contact point. Watchmakers appreciate how the tool sits in the hand for long sessions on the bench, while collectors value the reassurance of a tool that will not scratch a precious case 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 strap and case-screw removal tool whenever a routine intervention can only be carried out safely with a dedicated tool. A flat screwdriver, a kitchen knife or a coin will eventually mark the case-back, deform a screw-back groove or send a small part flying across the room. Typical situations include a flat battery on a quartz watch, a deteriorated O-ring on a diver's case rated to 100 m or 200 m, the installation of a new strap on a piece with screw lug bars, or the removal of a movement during a deep service. The tool is also valuable during inspection, when you need to look at a serial number engraved between the lugs without disassembling the head.

How to use it

1. Place the watch on a soft mat or holder, dial down, to protect the crystal during the operation.
2. Inspect the case-back to identify a screw-back, a snap-on cover or a four-screw plate, and choose the matching tip or bit accordingly.
3. Position the working tip of the watchmaker tool firmly against the engaging surface, keeping the axis perpendicular to the case.
4. Apply gradual pressure with a controlled torque, typically no more than 0.4 Nm on delicate closures, until the case-back releases.
5. Lift the cover straight up, set it aside on a clean cloth and protect the gasket from dust.
6. Perform the intended task (battery, gasket, hand setting, movement check) without touching the dial.
7. Refit the cover, ensuring threads or clips align, then apply moderate finger pressure to seat the screw-back or press-fit case-back.

Quality and provenance

Quality control on this tool follows the standards expected by professional Swiss watchmaking workshops. Materials are selected for their dimensional stability, the working tip is inspected for burrs and edge geometry, 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 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 strap and case-screw removal tool on a Rolex screw-back case?
Yes, provided the size of the working tip matches the case-back engagement. Reference manuals from Rolex recommend a torque below 0.4 Nm when seating a screw-back, which this tool allows by hand pressure alone.

Is the tool antistatic, and can I service a quartz movement with it?
For tweezers and pliers made from carbon fibre or specific polymers, yes. The tool minimises the risk of static discharge on quartz modules from Seiko or Omega, and is rated for cleanroom class 10 to 1000 environments where applicable.

How do I maintain a watchmaker tool of this type?
Wipe the tool with a dry, lint-free cloth after each session. Avoid solvents on plastic handles. Store the watchmaker tool in a closed drawer to protect the tip from accidental impacts and from dust that could be transferred to a watch case during the next service.
