The story · Since 2003
Cartier, the house of the Santos and the Tank, turned to the motor car for its first new collection of the 21st century: a tonneau case drawn from 1950s sports cars, a date magnifier shaped like a headlight, and straps that came off without tools. Dropped after about a decade, it came back at Watches and Wonders 2026.

A chronograph followed in 2003, with a Roman numeral dial and slightly oval sub-registers. A smaller size arrived in 2005, steel and gold and a GMT in 2006, and pastel blue, pink and purple dials from 2008.
The Roadster S of 2010 flattened the case and crystal, dropped the date magnifier and visible screws, and offered a black ADLC bezel on a rubber strap. Cartier ended production of the original Roadster around 2012.
Out of the catalogue, the Roadster built a following among collectors, car enthusiasts in particular. Cartier's Louis Ferla told Europa Star the house had noticed renewed interest in the model, including on the vintage market.
(April 2026) Back at Watches and Wonders: Cartier relaunched the Roadster with seven references in two sizes, large on the 1847 MC and medium on the 1899 MC. Four new rivets were added to the bezel, the bracelet got shorter links, and the bracelet uses the QuickSwitch system for tool-free strap changes.
The actor told Options (The Edge Malaysia) he bought a Cartier Roadster 'Las Vegas' with the rarer red-and-black dial early in 2026 and keeps it in his rotation.
At the July 2026 Goodwood Festival of Speed, where he sat on the Cartier Style et Luxe judging panel, the actor wore the not yet released medium Roadster in yellow gold and steel.
2026. Cartier unveiled the new Roadster at Watches and Wonders Geneva in April 2026. Louis Ferla told Europa Star the decision followed a convergence of signals from clients and the vintage market.
2016. Antiquorum sold a Ref. 2524 Roadster 'Emerson Fittipaldi' in yellow gold, its caseback engraved with the champion's signature, for USD 8,750 in New York on 8 October 2016, against an estimate of USD 4,000 to 6,000.
2014. Felipe VI chose a blue-dial Roadster for his proclamation before the Cortes Generales on 19 June 2014, a watch barely visible between his gloves and tunic cuffs. When Cartier relaunched the line in 2026, Vanity Fair read the new steel model with a dark blue dial and extra navy blue rubber strap as a direct nod to it.
The medium size uses the 1899 MC calibre in a 42.5 mm x 34.92 mm steel case with blue hands and a white dial.
Steel bracelet plus a second navy alligator strap, both with QuickSwitch.
A simplified Roadster with Cartier Calibre 049, sold in steel on a bracelet or with a black ADLC bezel on a patterned rubber strap; aBlogtoWatch priced them at $4,600 and $4,200.
Straps and bracelet release from the case without tools; the rubber strap tucks into a tension clasp.
An 18k yellow gold automatic made circa 2006, with an anthracite and red dial and a caseback engraved with the signature of the Brazilian two-time Formula One world champion. Antiquorum gives 37 x 44 mm and 10 mm thick.
Quick-change leather strap with an 18k gold Cartier deployant clasp.
In 2006 the line gained a GMT and steel and gold versions, a year after a smaller size joined it.
The chronograph kept the case, crown and crystal of the time-only model, added pushers, and returned to a Roman numeral dial with slightly oval sub-registers.

Every 2026 Roadster uses Cartier's patented QuickSwitch system on both the metal bracelet and the second strap, so they swap by hand. Swisswatches reports the system now carries a new patent.
Yes. Its tool-free swap between bracelet and strap was one of its most forward-looking features, and Japanese press described a lever release that freed the bracelet in one touch.
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.
