Skeleton Dial Artistry

The openworked dial showcases the movement's architecture. Rhodium or gold-plated bridges are skeletonized, with polished hands and indices filled with Super-LumiNova. The date window sits at 3 o'clock, month and leap year subdials at 12 and 9, while the moon phase at 6 features a realistic lunar disc.

The stainless steel bracelet—also available in leather or rubber—features alternating brushed and polished links, secured by a folding clasp with AP logo. It's comfortable, though clasp adjustment may be needed. The substantial weight mirrors the genuine, reassuring on the wrist.

Buying Guide & Authenticity Checks

To avoid inferior versions, scrutinize these details:

Movement finish: Look for clean Geneva stripes, not sloppy engraving.
Dial text: 'Audemars Piguet' and 'Automatic' must be sharp and evenly spaced.
Moon phase disc: Stars should be crisp, not blurred.
Date change: Should snap promptly at midnight.
Lume: Apply light; glow should be even.
Caseback: Deep engraving of movement number and logo.

Purchase from reputable sellers offering genuine photos and warranty. Prices typically range from $400 to $700, depending on source.

Styling Tips
