What it isA tool in its own right
Bench jobWorking on the movement

This 0.5 mm driver is ground for the small screw heads found deep in watch movements. The knurled barrel gives your fingertips purchase while the swivel head stays stationary under your index finger. We dress the blade flat so it seats straight into narrow slots.

Ground blade profile

We size the blade to 0.5 mm across the edge. The flat profile sits down into the slot of small movement screws so the turn comes directly from the barrel rather than an unsteady corner.

Chromium plated body

The knurled barrel is finished with chromium plating to handle daily bench use without rusting from skin contact. The textured band gives purchase to your thumb and forefinger when a delicate turn is needed.

Swivel head action

Your index finger rests on the free-spinning head to hold downward position while your other fingers turn the barrel. This keeps the tip steady in the screw head as you back out a bridge screw.

Replacing a worn blade

A small set screw in the side of the ferrule holds the blade in place. Back out the screw to remove a chipped tip, slide in a fresh 0.5 mm replacement blade, and tighten it down again.

A note that touches this tool

Reading a catalogue number

What the parts of a Bergeon reference number mean, why the number is how a tool is asked for, how a suffix marks a size or a variant of the same family, and how to find the spare blade for a handle you already own.

Choosing a blade width

Why a screwdriver is chosen by the width of its blade rather than by its name, what happens to a screw head when the blade is a step too narrow, how the blades are stepped through the range, and how a worn blade is dressed or swapped.
