The story of the Patek Philippe Cubitus

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.

Chapters

  1. 1932 to 1999

    Squares in the archive

    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.

  2. About 2020 to 2024

    A president's square watch

    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.

  3. October 2024

    Launch in Munich, after a leak

    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.

  4. 2025

    A 40 mm medium size

    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.

  5. 2026

    First grand complication

    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.

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.

FAQ

Can I put a strap on the bracelet models?

Not with a factory system: Monochrome notes there is still no quick-change system to swap the bracelet for a strap.

How is the 45 mm or 40 mm size measured?

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.

Which Cubitus comes on a strap?

The platinum complications: the 5822P and the 2026 5840P use a navy blue composite strap with a platinum fold-over clasp.

How do I adjust the bracelet?

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.

Help

What is lug width?

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.

Measure it in 30 seconds

  1. Take the strap off, or look at the back of it: many straps print their width.
  2. Measure the inside gap between the lugs with a caliper or a millimetre ruler.
  3. Round to the nearest whole millimetre. Most watches use 18, 20 or 22 mm.

Strap, quick release or system?

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.
