Rolex will put four unique Cosmograph Daytonas up for auction this month, each built around a season and finished in a different precious metal and set of gemstones. The sale, overseen by Phillips, takes place in London on September 28, 2026.
Rolex rarely confirms that any of its watches is a genuine one-off, which makes a set of four unusually notable. Hodinkee puts the combined estimate at around 4 million CHF, roughly $5 million. The four watches are estimated to be worth 4 million CHF, around $5 million, according to Hodinkee.
Four seasons, four stone settings
Spring wears an 18-karat gold case with a bright green chrysoprase dial, baguette and square-cut purple diamonds on the hour markers, a bezel set with 36 trapeze-cut purple sapphires and 54 brilliant-cut diamonds on the lugs. Summer carries a turquoise dial with pink sapphires.
Autumn is finished with a mustard-colored mookaite dial surrounded by green tourmalines. Winter closes the set with a blue opal dial, diamond hour markers and a gradient of sapphires running from blue to fuchsia. Rolex used Everose or white gold and 950 platinum across the four cases alongside the yellow gold piece.
Proceeds will go to two charities tied to Rolex testimonees. Roger Federer's Federer Foundation funds early learning access for children in South Africa and Switzerland, and Leonardo DiCaprio's Re:Wild works on ecosystem protection and restoration. Rolex CEO Jean-Frédéric Dufour said in a statement that excellence is measured by impact as well as by product quality. The sale result, once Phillips reports it, will show whether bidders value the charitable tie-in as much as the rarity. The auction will take place in London on September 28, 2026.
