The story · Since 1932
On 17 October 2024 Patek Philippe unveiled its first entirely new collection in 25 years: a square with rounded corners, 45 mm across the diagonal and 8.3 mm thin, that its president had been dreaming of for more than a decade.

Patek Philippe's collections arrived one by one: Calatrava in 1932, Golden Ellipse in 1968, Nautilus in 1976, Gondolo in 1993, Aquanaut in 1997, Twenty~4 in 1999. The Patek Philippe Museum holds square, rectangular, trapezoid and cushion cases, particularly from the Art Deco period, and GQ points to the gold 1970s reference 3854 as a square ancestor.
Thierry Stern wanted a square watch in the collection and named the project Cubitus himself. Work began about four years before launch, starting from a new big date movement; a year of weekly meetings pushed early sketches, too traditional or too bulky, towards the codes of the Nautilus and Aquanaut.
Days before the launch an advertising image escaped online, which Stern called disappointing and shocking. On 17 October 2024 three references were unveiled at the Bergson, a former power station in Munich: the steel 5821/1A, the steel and rose gold 5821/1AR and the platinum 5822P.
At Watches and Wonders 2025, barely six months after the launch, Patek added the 7128 in a 40 mm, 8.5 mm case in white or rose gold. aBlogtoWatch wrote that this is perhaps the size the Cubitus ought to have had from the start.
At Watches and Wonders 2026 the Cubitus received its first grand complication, the 5840P skeleton perpetual calendar, and its first shaped movement, answering critics of a round calibre in a square case.
GQ called him the first celebrity to wear the Cubitus: about a week after launch he showed a steel green-dial 5821/1A in an Instagram sauna video, taking it off before going in.
Seen at a Monza v Milan match in November 2024 with the platinum 5822P on its blue composite strap.
Wore the green-dial steel 5821/1A at the Cowboys v Commanders game on 24 November 2024. Something About Rocks reports the dial carried a Tiffany & Co. stamp, a claim GQ does not make.
Posted on Instagram in November 2024 wearing the platinum 5822P grand date and moon phase model.
British GQ reports him with a steel time and date model; personal wear, not a film role.
The Germany and Real Madrid defender showed the steel time and date model on Instagram during a Nations League trip to Hungary.
British GQ lists him among the first Cubitus wearers, without naming the reference.
2024. An image of one of the new watches circulated online days before the 17 October 2024 launch at the Bergson in Munich, prompting forum debate before Patek had said a word; Thierry Stern said he was disappointed and shocked.
2024. In the first weeks, Zlatan Ibrahimovic, Frank Lampard and Son Heung-min were all seen with the platinum 5822P grand date, while most other early wearers picked the steel 5821/1A.
At Phillips' New York Watch Auction XIV a 2024 platinum 5822P-001 with full set sold for US$177,800 against an estimate of US$60,000 to 120,000. Robb Report gave its retail price as US$88,380.

Not with a factory system: Monochrome notes there is still no quick-change system to swap the bracelet for a strap.
Patek gives the diameter from 10 to 4 o'clock: 45 mm for the steel 5821/1A-001 and 40 mm for the white gold 7128/1G-001.
The platinum complications: the 5822P and the 2026 5840P use a navy blue composite strap with a platinum fold-over clasp.
The bracelet has a lockable size-adjustment system and a patented fold-over clasp with four independent catches; Monochrome describes four positions of micro-adjustment.
The gap between the two lugs that hold the strap, in millimetres. A new strap must match it exactly: 20 mm lugs take a 20 mm strap.
Most watches use spring bars, so any strap of the right width fits. Many smartwatches use their own band system instead, such as Apple Watch bands or Garmin QuickFit.
