The black dial features three luminescent white hands, luminescent white indices, and two windows for the date and day at 3 o'clock. The case is fitted with a bidirectional bezel offering a visual countdown function. The crown is screw-down. The caseback is also sapphire crystal, revealing the movement's heart and its gears.
