| Step | Instruction |
|---|---|
| 1. Select Blade | Choose the blade that matches the screw size (the blade should fit perfectly in the screw slot) |
| 2. Select Torque Module | Choose the Dynometric module with the appropriate torque value for your application |
| 3. Assemble | Insert the torque module into the handle, then insert the blade into the torque module |
| 4. Operate | Hold the screwdriver vertically and apply steady pressure while turning. When the preset torque is reached, the blade will slip within the handle, preventing further tightening |
| 5. Change | To change sizes or torque, simply pull out and replace the blade or torque module |
| 6. Store | After use, return blades and torque modules to their designated positions in the aluminum case |
| Step | Instruction |
|---|---|
| 1 | Hold the handle and pull out the current blade and torque module |
| 2 | Select the desired torque module and insert it into the handle until it clicks into place |
| 3 | Select the desired blade and insert it into the torque module until it clicks into place |
| 4 | Gently pull the blade to confirm secure installation |
| Note | Details |
|---|---|
| Torque Selection | Select the appropriate torque value based on screw size and material. Use low torque for small screws, high torque for larger screws |
| Blade Matching | The blade must perfectly match the screw slot to avoid damaging the screw head |
| Vertical Operation | Always keep the screwdriver perpendicular to the screw to prevent slipping and blade damage |
| Genuine Product | This is a genuine Swiss-made Bergeon tool, not a counterfeit |
| Professional Use | Designed for professional watchmakers, ideal for precision movement repair |
| Storage | Store in the aluminum case after use to prevent blade damage or loss |
| Aspect | Guidance |
|---|---|
| Cleaning | After use, wipe the handles, blades, and torque modules with a soft, lint-free cloth. Avoid solvents |
| Blade Care | Regularly inspect blade tips for wear or rounding. Replace worn blades promptly |

| Blade Replacement | Use Bergeon 6899-T series conical blades or 7895-M series parallel blades |
| Storage | Store in the aluminum case in a dry environment, away from moisture |
| Calibration | Dynometric torque modules are factory-preset and cannot be user-calibrated |
Q1: What is the difference between the 7965-PREMIUM and the standard 7965 set?
A: The PREMIUM set includes the aluminum storage case and the full range of Tork-Speed Premium torque modules (10-45 mNm), offering a wider torque range and more professional presentation than the standard set.
Q2: What is the advantage of the Dynometric torque system?
A: The Dynometric system prevents over-tightening by causing the blade to slip when the preset torque is reached. This protects delicate watch movement screws and plates from damage.
Q3: What are the torque values in mNm?
A: The torque values range from 10 mNm to 45 mNm: 10, 15, 20, 25, 30, 35, 40, and 45 mNm. One mNm (milliNewton meter) is 1/1000 of a Newton meter – these are very low torque settings ideal for watchmaking.
Q4: What is the difference between conical and parallel blades?
A: Conical blades (6899-T series) are tapered for reaching recessed screws. Parallel blades (7895-M series) have straight sides for standard screw applications. The set includes both types.
Q5: Is this set suitable for professional watchmaking?
A: Yes, this is a premium professional-grade set designed for serious watchmakers, jewelers, and precision instrument repair technicians.
