Enamel dial

A dial made by fusing powdered glass to a metal disc, giving a hard, glossy, light-fast surface.

Explanation

An enamel dial is made by firing powdered glass onto a metal (usually copper) plate, giving a hard, brilliant white (or coloured) surface that does not fade or tarnish. Hairline cracks, chips at the edges and replaced dials are common; even small hairlines affect value. 'Enamel' on modern dials often means lacquer — true fired enamel is a specialist craft.
