摘 要:
A hand for a timepiece is formed in a two-
layer construction, from a hard metal
which is clad with a soft metal. The hard
metal layer permits secure fixing of the
hand to a shaft, as by a portion 12, while
minimizing the possibility of deformation
of the hand during such fixing. The soft
metal layer can be easily formed into a
desired pattern or be provided with a
surface finish to provide an attractive
appearance. The hand may thus be as
thin as 30-50 microns and may for
example be of nickel or stainless steel
clad with gold or copper. The hands are
blanked from a continuous strip using a
diamond- tipped tool. <IMAGE>
