A new caliber model in commemoration of the 40th anniversary of the world’s first hybrid diver’s watch with alarm and chronograph.

The original watch was launched in 1982 as the world’s first hybrid diver’s 150m which had a hybrid display with a digital display and three analog hands.

This model was highly accurate, reliable, and multifunctional equipped with alarm and chronograph function.

This new model adopts the newly developed Caliber H855, a solar quartz movement that further pursues the multifunctional features of the original model.

Essential functionality such as diving log function and a depth meter is added and the functionality for diving is updated from the current hybrid diver’s model.

Also, the visibility is improved by moving the display to the 6 o’clock position, making the size bigger.
