Abstract
A method of making aluminium hands for timepieces comprises annealing an aluminium hand member 2 at 160-200 DEG C for 20-60 minutes, forcing the flange 3a of a (brass) bush 3 into the lower surface of a seat portion of the hand member, forming a protrusion 6 on the upper surface of the seat portion of the hand member, shaping the upper surface of the hand member by pressing, and finishing the the protrusion on the upper surface of the seat portion by machining using a diamond cutting tool. As illustrated the bush 3 is staked in the band member 2 by tools 4, 5 prior to annealing. A pressing step using dies 8, 9 forces the flange 3a into the member 2 and simultaneously forms the protrusion 6. After machining the hand is coated with gold. <IMAGE>
