Abstract

PURPOSE: To obtain a timepiece dial having fine and beautiful patterns by blanking sheets obtained by electrocasting and forming patterns, and time characters.
CONSTITUTION: An Ni electrocast sheet of about 5/100W7/100mm thicknesses copied with desired patterns and about 3/100W6/100mm Ni-Co alloy electrocast sheet 6 are obtained by using an electrocasting mother plate 5 engraved beforehand with patterns for base. On account of the need for high degrees of evenness, stress control is accomplished precisely during electrocasting. In exactly the same manner, electrocast sheets of Au, Ag are made. These electrocast sheets are blanked to required outside shapes with a press, whereby a dial 7 for wristwatches engraved with extremely thin and beautiful patterns is obtained.
