1. What Is an Annual Calendar?
An annual calendar complication is a clever middle ground between simple date and perpetual calendars. It automatically adjusts for:
- 30- and 31-day months
- Only requires manual correction once per year (on March 1st)
Patented by Patek Philippe in 1996, it is one of the brand’s most popular complications thanks to its usability and mechanical brilliance.
2. Case Design and Size
- Case Diameter: 40mm
- Thickness: 11.36mm
- Material: 18k White Gold
- Water Resistance: 30 meters
The 5205G’s case features elegant concave lugs and a stepped bezel, creating an architectural yet dressy silhouette. The polished white gold exudes refinement without ostentation.
3. Dial: Function Meets Form
- Gradient dial from charcoal to black
- Aperture windows at 10, 12, and 2 o’clock (day, date, month)
- Moonphase and 24-hour subdial at 6 o’clock
- White gold dauphine hands and applied markers
The layout is symmetrical and modern, maintaining clarity while delivering complication. The moonphase disc is richly detailed, adding visual intrigue.
4. Strap and Clasp
- Shiny black alligator strap with large square scale
- 18k white gold fold-over clasp engraved with Calatrava cross
This strap is classic and business-ready, securing the watch firmly while complementing its case and dial.
5. Movement: Caliber 324 S QA LU 24H

6. On the Wrist: Confident and Contemporary
The 5205G wears like a modern classic:
- Ideal for business, formal, and elegant casual settings
- Thin enough to slide under a cuff
- Versatile enough for daily wear without losing prestige
Its visual punch comes from the apertures and moonphase, while the white gold keeps things dignified.
7. Price and Collector Demand
- Retail Price: ~$53,000 USD
- Secondary Market: ~$58,000–$70,000 depending on condition
