ABSTRACT:
A method of manufacturing a timepiece hand is disclosed, whereby the hand can be made extremely thin and lightweight, as well as strong and rigid. The timepiece hand is in the form of an open shell formed of hard nickel electro-forming. Because a minimum of mechanical working is performed upon the hand during the manufacturing process, bending distortion of the hand is avoided, and such a hand can be made substantially thinner than has been possible with manufacturing methods of the prior art.
