In modern quartz watches, the timekeeper is a quartz crystal in an electronic circuit, powering a small stepper motor. Because of the small amount of torque needed to move the hands, there is almost no pressure on the bearings and no real gain by using a jewel bearing, hence they are not used in a large proportion of quartz movements.
