Patek Philippe 6159G: the perpetual calendar with a see-through dial
The Cotswold Jeweller · 14 October 2026
Introduced at Watches and Wonders in April 2025, the 6159G is one of the most striking perpetual calendars Patek Philippe has made in years. Its smoked sapphire dial lets you see the calendar mechanism at work beneath.
A dial you can see through
The dial is made of sapphire crystal with a translucent grey metallic coating that darkens towards the edge. Look closely and you can make out the wheels and levers of the calendar beneath. Patek first tried the idea in blue on the platinum 5316/50P in 2023; here it's used on a regular-production watch, not a limited edition.
- Day at 9 o'clock, month at 3, leap year at 12 and the moon phase at 6.
- A retrograde date: a red-tipped hand sweeps across the top of the dial and, at the end of each month, snaps back to the 1st.
- No correction until 2100, as long as it's kept running. The moon phase is accurate to one day in 122 years.
Case and movement
The 39.5mm white gold case is 11.49mm thick, shares its shape with the Calatrava 6119, and has a hobnail (Clous de Paris) pattern on the bezel and caseback. Inside is the self-winding calibre 26-330 S QR, with 368 parts, a 21ct gold rotor and 35 to 45 hours of power reserve. It comes on a black fabric-effect strap with Patek's folding clasp.
Price
Patek's US price rose from about $117,800 at launch to just over $130,000 by October 2026, an increase of around 10% that has been put down to changes in Swiss import tariffs to America. Dealers ask more on the secondary market.

The perpetual calendar is one of the great complications, and Patek made the first perpetual calendar wristwatch in 1925. To learn more about how they work, read watch complications explained, or the history of Patek Philippe.
