It is impossible to make a watch accurate to within one second per year without insisting on extreme precision in all the components that go into that watch.

Eco-Drive has been continuously improved for over 40 years. By combining multiple technologies developed over this time, CITIZEN has created Caliber 0100.

It is an Eco-Drive watch that marks — and keeps marking — each pure, individual second, beautifully, confidently and proudly.
