Five hundred and twenty-five. That is the number engraved on the caseback of Breitling's latest Top Time — "ONE OF 525" — and if you know cycling, you know exactly whose number that is.
Eddy Merckx won 525 professional races. Five Tours de France. Five Giri d'Italia. A Vuelta. Three World Championships. Seven Milan–San Remos. The Hour Record on a steel bike at altitude in Mexico City. Classics, stages, prologues, kermesses — the man consumed them all. They called him The Cannibal, and nobody has ever worn that nickname more accurately. He did not just want to win the race. He wanted the stage. The intermediate sprint. The mountain prime. The time bonus at the feed zone. He wanted everything, and for the better part of a decade, he took it.
Five hundred and twenty-five is not just a big number. It is an unreachable number. Pogačar — the best rider on the planet right now — averages around 55 race days a year. The modern calendar, the modern body, the modern team structure simply does not produce 525-win careers anymore. Merckx raced over 1,800 times. He won roughly one in every three and a half starts. For thirteen years.
Breitling has put all of that on the wrist, and the number is the point.
The watch
The Top Time B01 Chronograph 41 Eddy Merckx (ref. AB01762C1I1X1) is the third cycling edition in Breitling's Top Time collection, following the Fausto Coppi and Gino Bartali pieces that launched in 2025.
The dial is yellow — a proper, committed yellow, not a muted cream trying to be polite about it. The colour is a direct nod to the maillot jaune, the jersey Merckx wore for a total of 96 days across his five Tour victories, and it dominates the face of the watch in a way that makes the Coppi celeste and Bartali blue look restrained by comparison. White sub-counters at three and nine o'clock carry the chronograph minutes and running seconds. "EDDY MERCKX" is printed in orange along the tachymeter ring between one and two o'clock. Merckx's signature sits above the six o'clock marker in black. The chronograph seconds hand is blue — a sharp contrast against all that yellow — and the applied hour markers are polished steel.
At 41mm in stainless steel, it wears the same as the Coppi and Bartali editions — big enough to be legible, small enough that it is not shouting at you. The case mixes polished and brushed surfaces: polished bezel, polished chronograph pushers, brushed mid-case flanks. The black perforated calfskin strap has rally-style perforation on the outside and a yellow lining visible at the lugs — a detail that ties back to the dial and reinforces the maillot jaune reference without needing to say so.
Flip it over and the caseback tells you everything. "ONE OF 525" at twelve o'clock. "EDDY MERCKX TRIBUTE" along the left side. An exhibition window showing the movement. "CHRONOMETRE OFFICIELLEMENT CERTIFIE" around the perimeter, because this is a COSC-certified chronometer, and Breitling has earned the right to say so.
$8,050. That is the price. It puts the Merckx below the Coppi and Bartali editions, and below Tudor's Bumblebee at $6,725. For an in-house COSC chronograph from a manufacture-level brand, limited to 525 pieces, with a genuine connection to the greatest cyclist who ever lived, that number is competitive.
The movement that connects cycling's watches
Inside sits the Breitling Manufacture Calibre 01. Column wheel. Vertical clutch. Silicon balance spring. COSC-certified. Seventy hours of power reserve at 28,800 vibrations per hour.
If you read the Coppi and Bartali piece or the Tudor Bumblebee piece, you already know where this goes. Tudor's Manufacture Calibre MT5813 — the engine inside the Black Bay Chrono 39 — was developed in partnership with Breitling using the Calibre 01 as its base architecture. Same column wheel, same vertical clutch, same 70-hour power reserve, same COSC standard. The Breitling cycling watches and the Tudor cycling watch are mechanical cousins. Different finishing. Different specifications. Same bones.
The Swiss watch industry keeps circling back to cycling, and the movement architecture underneath is smaller than any of them would like to admit.
The man who ate the sport
Every cycling fan knows Merckx won a lot of bike races. Most people do not know how many, or how absurdly varied the list is. It is worth pausing on the palmares, because the 525 figure is not a vanity stat — it is a record of total domination across every discipline the sport had to offer.
Five Tours de France: 1969, 1970, 1971, 1972, 1974. He took the yellow jersey, the green jersey, the mountains classification, and the combination classification in the same race. In 1969 — his first Tour — he won by almost eighteen minutes. He won six stages in that single edition. The field was not weak. He was just that far ahead of everyone.
Five Giri d'Italia: 1968, 1970, 1972, 1973, 1974. The pink jersey five times, the points classification twice. He won the Giro-Tour double three times — a feat so difficult that only a handful of riders have managed it even once.
One Vuelta a España, in 1973 — the year he completed the Vuelta-Giro-Tour treble, winning all three Grand Tours in a single season. Nobody else has done that.
Three World Championships: Heerlen 1967, Mendrisio 1971, Montréal 1974. He wore the rainbow jersey three times and raced in it with the same ferocity he brought to everything else.
Seven Milan–San Remos. Five Liège–Bastogne–Lièges. Three Paris–Roubaix. Two Tours of Flanders. Two Giri di Lombardia. He won Amstel Gold, Flèche Wallonne, Het Volk, Paris–Nice, the Critérium du Dauphiné, the Tour de Suisse. He won on cobbles, on mountain passes, in time trials, in bunch sprints, in breakaways of one. There was no terrain, no race format, and no tactical situation where Merckx could not win. That is what separated him from every other great champion — the total absence of a weakness.
And then there was the Hour Record. October 25, 1972. Mexico City. Altitude: 2,250 metres. Merckx rode 49.431 kilometres in sixty minutes on a steel-framed track bike, and when he climbed off, he said it was the hardest thing he had ever done. I wrote about that in Against the Clock — Merckx set the record and never went back to the velodrome. Once was enough. The number stood for twelve years.
The nickname was not a joke. "The Cannibal" came from his own daughter's schoolfriend, who watched Merckx win yet another race and asked why he had to eat everyone. It stuck because it was true. Other champions win what they need to win. Merckx won because the race existed.
Breitling's cycling collection — where it stands
The Top Time started life in the 1960s as a motorsport chronograph. Shelby Cobras, Ford Mustangs, Triumph Speed Twins — that was the Top Time's territory for decades. Breitling's decision to swing the collection toward cycling started with the Coppi and Bartali watches, which told the story of the rivalry that fractured post-war Italy. Those were ambitious first steps — limited to 750 pieces each, grounded in deep cycling history, priced in the same corridor as Tudor's entry into the sport.
The Merckx is the third chapter, and it extends the logic. Coppi and Bartali gave Breitling the rivalry. Merckx gives them the individual — the one rider whose name appears in every cycling argument, every palmarès comparison, every debate about who is the greatest. The limitation to 525 pieces — rather than 750 — ties the production number directly to the man's career wins. It is a neat idea, and it makes the number mean something beyond artificial scarcity.
Three watches. Three figures from cycling's history. Each one a legitimate story, each one carrying the same Calibre 01, each one under $10,000. Compare that to what is happening at the other end of the cycling-watch spectrum — Richard Mille strapping $350,000 watches to the wrists of Pogačar and van der Poel — and Breitling's approach looks like a different philosophy entirely. Less about the contemporary peloton, more about the archive. Less about who is winning today, more about what makes the sport worth caring about in the first place.
The question now is where the collection goes next. Coppi and Bartali covered Italian cycling's golden age. Merckx covered Belgium's greatest champion and, arguably, the sport's greatest full stop. There are other stories in the archive — Anquetil, Hinault, Indurain, the track legends, the Classics specialists — and the Top Time platform is flexible enough to tell any of them. Breitling seems to be building a horological record of the sport, one limited edition at a time.
The watch industry and cycling — why this keeps happening
I keep writing about this, and the trend keeps accelerating. Tudor built an entire professional cycling team and put its name on the jersey — the only watch brand in history to do that. Tissot times the Tour de France. TAG Heuer had its name on a team kit. Richard Mille is impossible to miss on race-day wrist shots. Now Breitling is three watches deep into a cycling archive project.
The connection between the watch industry and cycling is not accidental. I wrote about this in detail in Against the Clock — cycling is one of the only major sports that scores itself in time rather than points. The chronograph and the time trial grew up together. Breitling made its name as a chronograph manufacturer, and the chronograph was literally built to measure elapsed time. Cycling measures everything in elapsed time. The marriage is obvious once you see it.
What makes Breitling's approach interesting is the editorial decision. They are not chasing the contemporary peloton. They are not paying a current rider to wear the watch in a press photo. They are going back to the figures who built the sport — Coppi, Bartali, Merckx — and letting the history carry the weight. Whether that is a better strategy than Tudor's all-in team sponsorship or Richard Mille's individual ambassador model is a question the market will answer over the next few years. But from a pure cycling perspective, the Breitling approach resonates. The stories they are choosing are the right stories.
Should you care
If you are a cyclist who also happens to appreciate mechanical watches — and I know a decent number of you are — the Merckx is worth looking at. The yellow is bold. The movement is proven. The limitation to 525 is not a marketing number; it is the number, and it connects the watch to something real in the sport. The caseback engraving — "ONE OF 525" — means more on this watch than "Limited Edition" has ever meant on any other.
At $8,050, it is not a casual purchase, but it is a fair price for what you are getting. In-house COSC chronograph, 70 hours of power reserve, 525-piece limitation, a genuine connection to the greatest palmarès the sport has ever produced. The Coppi and Bartali editions, limited to 750 each, sold out. Five hundred and twenty-five is a tighter number. If the Merckx follows the same pattern, the window will not stay open long.
The perforated strap with the yellow lining is a nice touch — it references rally chronograph heritage while pulling the maillot jaune colour through to the wrist. The exhibition caseback lets you see the Calibre 01 doing its work. And the yellow dial is the kind of thing you either love immediately or you do not, which, given the man whose name is on it, feels about right. Merckx was never subtle. Neither is this watch.
