SCREWDRIVERS
Along with the loupe and Tweezers, Screwdrivers are among the essentials of the Horologist (watchmaker). Horologists’ Screwdrivers stand out due to their design and use.
The hardened Steel Blade of the Screwdriver is removable and screwed into the body of the Screwdriver, usually made of Brass or Aluminium. The top of the Screwdriver’s body ends in a plate set on a ball bearing.
To tighten or loosen a Screw, the Horologist (watchmaker) grips the cylindrical part of the Screwdriver body between the thumb and middle finger and maintains light pressure on the Screw by placing the Index (hour marker) at the center of the head. By rolling the Screwdriver body between the thumb and middle finger, the Horologist (watchmaker) tightens or loosens the Screw. Screws used in watchmaking generally have straight slots, so Screwdrivers have flat Drill bits of different sizes. Using a stone, the Horologist (watchmaker) can modify or shape their Screwdrivers to have a Drill bit perfectly suited to the Screw’s slot and to avoid marking (damaging) the Screw.
In production, torque Screwdrivers are commonly used to ensure a defined tightening torque. In this case, the Screwdriver mechanically disengages once the determined tightening torque is reached.
