1. What Is a Perpetual Calendar?
A perpetual calendar automatically adjusts for:

3. Dial: Elegance Through Symmetry
- Cream-colored lacquered dial
- Gold applied Breguet numerals
- Leaf-shaped hands in matching gold

The layout is clean and symmetrical, despite the wealth of information displayed. Legibility is exceptional for a complication of this scale.
