The watch employs a rotating bezel that allows the crown to be locked or unlocked with a simple movement. In the standard position, the crown remains concealed within the bezel to help prevent accidental operation. Rotating the bezel by 45 degrees brings the crown into view at the lower right, allowing time and date settings. Visual indicators linked to the bezel rotation show the lock and unlock status at a glance, while the shape of the crown guard is carefully considered. Ensuring intuitive, easy operation, the design also offers a subtle sense of playfulness.
