Why this one
The case for this one.
- White gold Annual Calendar with day, date and month set beneath 10, 12 and 2 o'clock
- Silver dial with a moonphase and AM/PM subdial at six, visible under a flat sapphire crystal
- Automatic Caliber 324 S QA LU 24H, viewable through the exhibition case back
The 5205 keeps its complication modest by Patek standards, an annual calendar that only needs adjusting once a year at the end of February, and lets that restraint show in the dial layout. Three apertures arc across the top of a silver dial, while a moonphase and 24 hour indicator share a single subdial at six, kept legible by slim baton markers and tapered white gold hands. At 40mm in white gold, it sits closer to a modern dress watch than a vintage Calatrava, with the automatic movement visible through a sapphire case back.
