The 24-cities disk is completely embedded into the movement, and it is visible on the 9 o’clock side of the case. This elegant solution helps to keep the dial clean and easy to read. The time in various cities is read by pressing the pivoting button.

The lower silvered dial features transferred Arabic numerals, making a nice contrast and providing additional depth.

The lower dial indicates home time, together with delicate blued day and night hands shaped like sun and moon symbols. Local time is shown by the main hands, as indicated in the upper dial.
