Standard 0.01mm graduation dial gauges having a bezel with an outside diameter of ø57mm. All types come with limit pins and a bezel clamp. The outer clamp and lifting lever (optional) can be attached to either the right or left side. These parts can be easily installed and removed without tools. Secure adhesion between the bezel and crystal as well as the use of an O-ring ensure prevention of water and oil ingress via the front face. The spindle is made of high-strength quench-hardened stainless steel which resists arduous use. A carbide contact point is used. The crown gear uses stainless steel that is resistant to wear and deformation. Application of a hard coating on the surface of the crystal makes the gauge highly scratch- and chemical-resistant. A special alloy is used for the sector gears to provide improved wear resistance. The indicator uses jeweled bearings, providing excellent indication sensitivity and durability.
