The Rolex Daytona Le Mans is the factory reference 126529LN, a 40 mm white gold Cosmograph Daytona that Rolex introduced in June 2023 to mark the 100th running of the 24 Hours of Le Mans. What sets it apart from the standard Daytona is its own movement, the calibre 4132, whose chronograph hour counter reads to 24 hours instead of 12, along with a red "100" on the black ceramic bezel and a sapphire display back. This guide explains what the watch is, why Rolex made it, how it differs from the standard white gold Daytona, and how to tell it from the custom Le Mans-style watches that circulate. Bizak & Co. is a sourcing desk, not an authorised Rolex retailer, and every watch here is sourced on request.

What is the Rolex Daytona Le Mans 126529LN?
It is the Cosmograph Daytona that Rolex made for the centenary of the 24 Hours of Le Mans, the endurance race it has sponsored for more than two decades. Rolex presented it in June 2023, in the run-up to the 100th race. It is not a numbered limited edition, but supply has been tight since launch, because Rolex sells it only through its authorised retailers. The table lists the specification points that identify it.
| Attribute | Rolex Daytona Le Mans 126529LN |
|---|---|
| Case | 40 mm, 18 ct white gold, sapphire crystal |
| Bezel | Black monobloc Cerachrom with a tachymetric scale; the "100" is filled in red |
| Dial | Dark dial with contrasting white counters, styled after the vintage "Paul Newman" Daytona; Chromalight hands and markers |
| Movement | Calibre 4132, automatic chronograph with a 24-hour counter, Chronergy escapement, 72 hours of power reserve, Superlative Chronometer |
| Case back | Sapphire display back showing the movement |
| Bracelet | White gold Oyster |
| Water resistance | 100 m |
| Introduced | June 2023 |
Reviewers describe the dial colour slightly differently, from black to a very dark grey, so judge the shade on the actual watch rather than on a screen.
Why does the Le Mans Daytona have a 24-hour counter?
A 24-hour counter lets the chronograph time a full day of racing, which is exactly the length of the event. In a standard Daytona the register records up to 12 hours. In the 126529LN, Rolex adds reduction gearing so the same register turns once in 24 hours, a modification of the calibre 4131 that reportedly adds about seven parts. That is why the movement has its own name, calibre 4132, and why the watch carries a sapphire back: Rolex wanted the owner to see it. It is the clearest functional difference between the factory watch and anything built to imitate it.
What makes the 126529LN different from a standard white gold Daytona?
Five details separate it: the 24-hour counter, the red "100" on the bezel, the Paul Newman-style counters on the dial, the display back and the 4132 calibre. The standard white gold Daytona has a solid back and the 12-hour calibre 4131. The Le Mans is also a little thicker than the regular Daytona, according to reviewers who measured it. For the standard configurations, see our guide to the white gold Rolex Daytona.
How do you tell a factory Le Mans from a custom Le Mans-style Daytona?
Check the movement and the paperwork, not the dial. Custom builders start with an ordinary white gold Daytona and swap in an aftermarket bezel and dial, but the watch underneath is still a different reference with its own movement. Those parts are not made by Rolex. Our companion guide to the custom 126509 Le Mans-style Daytona goes through that case in depth; the checklist below is the short version.
| Check | Factory 126529LN | Custom Le Mans-style build |
|---|---|---|
| Hour counter | Makes one turn in 24 hours (calibre 4132) | Makes one turn in 12 hours (calibre 4131), even if the dial is printed differently |
| Case back | Sapphire display back | Solid back, unless that too has been changed |
| Warranty card | Reads 126529LN | Reads 126509 or another base reference |
| Bezel and dial | Rolex parts; red "100" and crisp printing | Aftermarket parts; inspect printing, lume and edge fit under a loupe |
| Rolex guarantee | Applies as issued | Generally excluded for non-genuine parts; confirm with Rolex |
The simplest test is to run the chronograph and watch the hour counter. If the hand does not take a full day for one turn, it is not a 4132.
Is the Rolex Daytona Le Mans a limited edition?
Rolex did not present it as a numbered limited edition, but it has not published production figures, and availability has been limited since launch. It is also not a permanent catalogue model in the way the steel Daytona is, so expect the reference to be hard to find. Because Rolex does not release volumes, treat any claim about how many exist as unverified.
How do you buy a Rolex Daytona Le Mans?
You ask a sourcing desk to find a specific unit, then confirm it before you commit. Bizak & Co. sources the Rolex Cosmograph Daytona 126529LN on request: you tell us what you want, we locate a unit, and we confirm the reference, the paperwork and photographs of that exact watch before the balance is due. Our catalogue also lists the modified 126509 Le Mans-style Daytona separately and states in the listing that it is customised. Nothing on this page is stock; both are sourced to order. For context on the other precious-metal options, browse our white gold Daytona collection, the wider Rolex Daytona collection or the Daytona diamond bezel references.
