Jaeger Instrument Glass Replacement Replace cracked, scratched or missing flat glass in Jaeger speedometers, tachometers, clocks and auxiliary instruments. Phoenix Wing Mirrors supplies precision-cut clear round glass for classic vehicle and specialist instrument restoration. The current range is manufactured from 2mm flat glass in the UK and is available in 1mm diameter increments. Both edges are wet-finished to create a clean component for installation into the original instrument bezel or housing. Jaeger instruments were produced in many sizes and styles, so check the original glass diameter and thickness carefully. Select the exact required diameter from the product options.
