Q1: Is this a genuine Bergeon tool?
A: Yes — this is a genuine Bergeon 31081-NOV26/28 Novodiac Shock Spring Screwdriver, Swiss-made professional watchmaking tool. It is an authentic Bergeon product, not an aftermarket copy.
Q2: What is a Novodiac shock spring?
A: A Novodiac shock spring is the tiny spring component in ETA’s Novodiac (incablok-style) shock protection system. It sits within the shock absorber and helps the jewel return to center after impact. These springs are extremely small and delicate — improper handling can easily bend, launch, or lose them, which is why a dedicated screwdriver is essential.
Q3: Why do I need a special screwdriver for shock springs?
A: Novodiac shock springs are tiny, under tension, and easily damaged or ejected during handling. The Bergeon 31081-NOV26/28 is precision-engineered with the correct tip geometry to securely grip and control the spring during assembly or disassembly, preventing damage that standard tools would cause.
