The Cartier Roadster Chronograph W62020X6 is the blackout Roadster — the most aggressive watch the collection ever produced. The XL tonneau case stretches to roughly 43 mm across the wrist, the black satin sunray dial carries white Roman numerals and three chronograph counters, and the magnified date sits under the signature cyclops. With 100 meters of water resistance and an automatic chronograph inside, this was Cartier at full throttle, built through the 2000s and retired with the rest of the line in 2012.
Like every Roadster, it lives or dies by its strap system — and that system takes nothing off the shelf. This guide covers the correct size for the W62020X6 and the most popular Helvetus options for it.
Cartier Roadster Chronograph W62020X6 Strap Size and Fit
For the Cartier Roadster Chronograph W62020X6:
- Model: Roadster XL Chronograph, automatic
- Case: tonneau-shaped, steel, approx. 43 mm wide
- Attachment: Cartier Roadster interchangeable strap system — no standard spring bars
- Strap width at the case: 20 mm
This means the watch requires a 20mm strap made for the Roadster system. When ordering, simply select the 20mm option on the product page.
Pay attention to that number, because the Roadster family splits by size: the Ladies models take 15mm, the standard Large models take 19mm, and the XL Chronograph — this reference — takes 20mm. The sizes are close enough that Chronograph owners regularly order 19mm by mistake. Yours is the 20.
And as with every Roadster, a generic 20 mm strap will not work at all: the strap slides into the case rather than mounting on spring bars, with shaped ends following the tonneau curves. Helvetus Roadster straps are built for exactly this system — tool-free in, flush against the case, off again in seconds.
The Fastest Cartier Ever Built
If the standard Roadster was Cartier's tribute to vintage sports cars, the XL Chronograph was the racing version — bigger, bolder, and dressed in black. It divided opinion when new and has aged into exactly what its buyers wanted: an unmistakable statement watch with genuine sporting credentials, priced on the pre-owned market well below its presence.
Ownership has one recurring chore. Original Roadster straps wear out, the model is long discontinued, and replacements built for the slide-in system are the only ones that fit. The silver lining is the system itself: Cartier designed this watch for effortless strap changes, so a small rotation turns one Roadster into several.
The Best Straps for the Cartier Roadster Chronograph W62020X6

Below are the most popular choices among owners of this reference, matched to its black sunray dial and steel tonneau case.
Black Rubber Strap
Black on black is what this reference was born for. The strap disappears into the dial, the steel case and white Romans do the talking, and the XL Chronograph becomes a full stealth sports watch — waterproof, comfortable, and menacing in the best way. The definitive choice for this dial. Black Rubber Strap for Cartier Roadster
Grey Rubber Strap
Grey picks up the steel case and the white numerals, breaking up the blackout without softening it. It reads technical and modern — the pick for owners who want contrast with the black dial while keeping the sporty character intact. Grey Rubber Strap for Cartier Roadster
Brown Rubber Strap
Brown against a black racing dial is a classic motorsport pairing — driving gloves and bucket seats. It gives the XL Chronograph vintage warmth that no other combination delivers, and the rubber keeps it practical for daily wear. Brown Rubber Strap for Cartier Roadster
Flat Black Leather Strap
Matte black leather calms the big chronograph into evening territory. Same stealth palette, dressier texture — the strap that lets the loudest Roadster clean up for dinner. Flat Black Leather Strap for Cartier Roadster
The collection also includes nylon and further colors, all built for the same Roadster fitting.
