AQUALAND DEPTH METER

Challenging Design

Throughout its history of over 100 years, CITIZEN has produced numerous world firsts and world records. This article introduces epoch-making products that have pioneered new possibilities for watches by incorporating the technology of each era.

Visibility

For diver's watches used in life-critical diving situations, not only water resistance but also 'visibility' is considered essential. This model is equipped with the world's first electronic depth meter function. In addition to measuring the current and maximum depth, it also features an alarm function that is easy to hear underwater. However, the most important information is still the dive time. The deeper you go, the more your judgment declines, so this model pursues instant readability of the hands, carefully considering the size, shape, and luminescence area of the indexes and hands. It is truly a pioneering model that could be called the "bible of diver's watches."
