ANNUAL CALENDAR. MOON PHASES.

A sporty version of the Annual Calendar

This Annual Calendar with 24-hour indication and moon phases features a blue dial inspired by the original 1976 Nautilus model, enhanced by an embossed horizontal pattern and subtle black-gradient rim: a powerful, refined decoration blending perfectly with the gleam of steel. Beneath this "sporty elegant" exterior beats a 339-component self-winding movement.
