The start and stop function is intuitively operated via both pushers at 2 and 4 o'clock. The upper pusher starts and stops the chronograph hand, while the lower one resets it back to 12 o'clock – just like a mechanical chronograph.

During the stop process, the left subdial displays the elapsed minutes, while the right subdial serves as a 24-hour indicator to keep track of the day. Inside the chronograph, the Seiko VK64 Mecha-Quartz movement ensures precise timekeeping and a smooth sweeping seconds hand. The mechanically driven chronograph hand takes five steps per second, moving significantly smoother than the typical second tick of a classic quartz watch. Thanks to this movement, the date window is also bigger.

The design of the chronograph follows the Bauhaus principle of "form follows function": The pusher at 2 o'clock shares the same distinctive color as the large chronograph hand and the left subdial (stop minute), emphasizing their connection.
