However, no mechanical movement could ultimately compare to the accuracy of the quartz movements being developed.

It never entered competition because quartz movements arrived in 1967.

The company launched its first quartz movement in 1972.

Only the advent of the quartz movement shut off the bonanza.

This technology only works with quartz movements as a mechanical movement does not work properly in the oil filled case.

And thanks to their accurate quartz movement you need never be behind time.

In a traditional design, with up-to-the-minute quartz movement, it measures 15- x11in.

Outside the radio reception areas, the watch runs with a normal quartz movement.

But its accuracy won't be as good as a quartz movement.

Then there are different levels of quality for quartz movement.
