Abstract (en)
The hand has an hour wheel (12) with slots (14) which are open on an end opposite to the hand and extend on a part of its length so that the wheel elastically deforms for being fixed around a motor stem. The wheel has an inner channel with a portion (16a) having a diameter less than that of a portion (16b) situated at a side of the hand, where the diameter difference is between 0.01 and 0.04 millimeter. An independent claim is also included for a method for manufacturing a slot of an hour wheel of a watch hand.
