When Tyler Reddick gunned his no. 45 23XI Racing Chumba Casino Toyota into first place at the Daytona 500, securing the team’s victory at NASCAR’s marquee event, no one—except perhaps Reddick himself—was more thrilled than team co-owner Michael Jordan. “I’m ecstatic,” Jordan said, “I don’t even know what to say. It feels like I won a championship, but until I get my ring, I won’t even know.”

Despite the Daytona International Speedway’s close association with the Rolex Daytona, which was named after the track, Jordan chose to wear another revered but much lesser-known Swiss brand for the big day. MJ’s choice ​​was the Greubel Forsey Double Tourbillon 30° Technique, a skeletonized sequel of sorts to Greubel Forsey’s Double Tourbillon 30˚ Contemporain Vision, the high-end independent brand’s very first watch from 2004. A long-time fan of Greubel, Jordan knows a good, complicated timepiece when he sees one.

And complicated the Double Tourbillon 30° Technique is. Housed in a substantial black ADLC-coated titanium case measuring 47.5mm—which looks tiny on MJ’s substantial wrist—it features as its centerpiece a double tourbillon in which an outer cage rotating once every four minutes contains an interior cage inclined at 30 degrees that rotates once per minute. Got all that? TL;DR: The tourbillon cancels out timing errors resulting from “positional” errors—i.e, the wristwatch being held in different positions as it’s worn on the wrist. (In reality, a $15 digital watch is more accurate and cheaper…but we’re not here to talk about that. We’re here to admire the precision of a multi-six-figure piece of Swiss horological artistry!)

The double tourbillon isn’t even the half of it. The open sapphire dial reveals not only the spinning cages containing the watch’s balance, but also luminous white gold hands, a 120-hour power reserve with an indicator at 3 o’clock, four co-axial mainspring barrels, and a small-seconds indicator at 9 o’clock. The movement finishing is, of course, superb, with interior angles galore and lots of golden chatons—the small components that fix jewels within a watch movement—calling back to classical watchmaking. All of which is to say, it’s a watch befitting an enthusiast of the highest order, with or without a NASCAR championship ring.
