The Strange History of the Word ‘Calatrava’
From an eighth-century Islamic fortress to Patek Philippe, this is how one word traveled 1,200 years to become watch-collector shorthand.
Today, there are many words we use in watchmaking, watch collecting, and especially watch journalism, which are words that, dare I say, have become ubiquitous. They get thrown around so often that somewhere along the way we stop asking what they actually mean.
These words, like maison, have become little more than filler and fodder, tossed into a story to make it sound slightly more elevated. The kind of word that, increasingly, feels like it was slipped in by some AI editing software because that’s what a watch article is supposed to sound like, adding one more piece to the deluge of reviews and write-ups that all somehow read the same.
Recently, what began as an exercise in watchmaking words that are particular pet peeves of mine quickly turned into a study of one specific term. Maybe it’s the former English teacher in me, or an innate love of etymology, but down the black hole of the internet I went to find out how we came up with the word “Calatrava.”

The word is now practically synonymous with Patek Philippe, and we’ll get to why in a second. But Patek did not invent the word Calatrava. In fact, it existed for more than a thousand years before a simple time-only wristwatch was even a thought in anyone’s head.
And yet, as anyone with an internet connection and even a passing curiosity about vintage watches knows, Calatrava isn’t used exclusively for Patek Philippe watches either. Search the secondary market and you’ll find the name attached to vintage Longines, IWC, Omega, Universal Genève, and countless other simple, round, time-only watches. These brands didn’t necessarily call them Calatravas. In many cases, they certainly didn’t. Dealers, collectors, auction houses, and writers did it for them.
Which raises a fairly simple question with a surprisingly complicated answer: What the hell is a Calatrava?
And perhaps more importantly, how did the name of an eighth-century Islamic fortress become shorthand for an entire genre of Swiss dress watch?
The History Of The Word
So let’s jump into our metaphorical time machine and go back — way back.
The Muslim conquest of the Iberian Peninsula began in 711, when Muslim armies crossed from North Africa and quickly overwhelmed much of the Visigothic Kingdom. A few decades later, in 756, ʿAbd al-Rahman I established the independent Emirate of Córdoba under the Umayyad dynasty. As Muslim rule expanded and consolidated across the peninsula, the routes connecting its major cities became increasingly important, and so did the fortifications protecting them.

By 785, historical records document a fortified Islamic settlement along the Guadiana River, strategically positioned on the route between Córdoba and Toledo. The fortress-city was known in Arabic as Qalʿat Rabāḥ, roughly translating to the “Fortress of Rabāḥ.” The qalʿa part is straightforward: in Arabic it means fortress or castle. Exactly who or what Rabāḥ referred to is less certain. The name has traditionally been associated with an early Muslim figure connected to the fortress, but the historical record isn’t clear enough to confidently tell you that Rabāḥ was some specific nobleman standing atop the walls in the eighth century.
Over the centuries, Qalʿat Rabāḥ passed from Arabic into the developing language of medieval Castile and gradually became Calatrava. Say the two aloud—qal-at-ra-bah, ca-la-tra-va—and the lineage becomes easier to hear. Arabic place names were absorbed into Castilian all over the Iberian Peninsula, their pronunciations and spellings changing along the way. Here, Qalʿat became Calat-, while Rabāḥ evolved toward -rava, leaving us with Calatrava. The name itself is essentially a linguistic fossil from al-Andalus, preserving a bit of medieval Arabic inside modern Spanish.
And remarkably, the name survived the fortress changing hands.
In 1147, Alfonso VII of Castile captured Calatrava. The Christian conquerors did not give their newly acquired fortress a new Christian name. They continued calling it Calatrava, the Castilianized descendant of the Arabic name it had carried for centuries.
That becomes important eleven years later.

In 1158, responsibility for defending Calatrava was given to Raymond of Fitero and the knights who followed him. From that group emerged a new Christian military order. And rather than naming themselves after Raymond, Castile, or some patron saint, they took the name of the place they had been charged with defending: the Order of Calatrava.
The famous Cross of Calatrava followed. In other words, the fortress did not take its name from the order, and the order did not take its name from the cross. It happened in exactly the opposite direction: the fortress gave its name to the order, and the order gave its name to the cross.
There is roughly a 370-year gap between the first documented Islamic Calatrava and the founding of the Christian Order of Calatrava. And that is what makes where we’re eventually heading with Patek Philippe so fascinating. The word Calatrava, now inseparable from one of the most traditional Swiss watches imaginable, ultimately traces its name back to an Islamic fortress in al-Andalus documented in the eighth century. The Christian military order came centuries later. The cross later still. Patek Philippe… seven centuries after that.
Nothing like nearly 1,200 years of linguistic history embedded in the name of a simple time-only watch.
Then Comes Patek Philippe
Which brings us, after our brief history lesson on linguistics and medieval fortresses, to Patek Philippe.
And if you’re expecting some grand story about why a nineteenth-century Geneva watchmaker decided to adopt the emblem of a medieval Spanish military order, I’m going to disappoint you. To save you the suspense: no one really knows. Or, at least, no one seems to know for certain. Patek Philippe itself says the reason for the choice “remains enigmatic.”

The strongest clue Patek offers points to Adrien Philippe rather than Antoine Norbert de Patek. The four arms of the Calatrava Cross terminate in stylized fleurs-de-lis, and Patek notes their resemblance to the lilies of French royal heraldry. Three fleurs-de-lis also appear on the arms of Eure-et-Loir, the French département where Philippe was born. Patek has suggested that the lily’s associations with prestige and sovereignty may have appealed to Philippe as an emblem for a high-end manufacturer.
But even Patek presents that as a possibility, not an explanation.
There are other theories, of course. Perhaps Philippe was drawn to the chivalric history and ideals associated with the Order of Calatrava. Perhaps the cross was simply a distinctive symbol available to be registered at a time when what we now think of as corporate branding was still taking shape. Maybe there is some other explanation entirely. Unless something turns up in an archive, we’re left with speculation.

What we do know is that the cross began appearing on Patek Philippe watches in the 1870s, and on April 27, 1887, the company formally registered the Calatrava Cross as its trademark. In other words, the Calatrava Cross was a Patek symbol long before there was anything resembling a “Calatrava” collection.
It would be another 45 years before the watch we now retrospectively recognize as the beginning of that lineage appeared.
In 1932, the same year the Stern family acquired Patek Philippe, the company introduced Reference 96. At the time, though, it was simply that: reference 96. There was no grand unveiling of “the Patek Philippe Calatrava,” because the watch wasn’t yet called a Calatrava.

Early examples used a caliber 12 movement supplied by LeCoultre, before Patek introduced its own caliber 12-120 in 1935. The watch itself was almost aggressively simple: a round, three-piece case measuring roughly 30.5mm, typically in precious metal, though stainless-steel examples were also produced; clean dials; restrained markers; and little in the way of decoration that didn’t serve a purpose. Case production included work from Antoine Gerlach for precious-metal examples and Taubert for steel cases.
I’m not going to disappear too far into the weeds of the ref. 96. Tony Traina has already written an excellent collector’s guide for Collectability if that is the particular hole you’d like to fall into. What matters for our story is that the 96 remained in production, in one form or another, for nearly four decades and established a design language that would become foundational to Patek Philippe: the simple, round dress watch.
But there is a strange wrinkle in the history.
Despite the Calatrava Cross having represented Patek Philippe since the nineteenth century, the watch itself still wasn’t officially called a Calatrava. According to histories from both Sotheby’s and Hodinkee, Patek did not formally use Calatrava as the name of this family of watches until 1985, more than half a century after the Reference 96 first appeared. (That said, it is important to note, Patek states on their website the collection has used that name since 1932).

That brings us to Reference 3919.
Introduced in 1985, the 3919 with its round case, small seconds, and unmistakable Clous de Paris bezel became one of the defining Patek Philippe dress watches of the era. And around this period, Calatrava finally moved from being the name of Patek’s historic emblem to something more: the name under which the manufacturer could gather its lineage of traditional round dress watches.

René Bittel is an important character in this period. An advertising man and marketing mind closely associated with Patek Philippe, Bittel understood the power of giving Patek’s products identities that extended beyond reference numbers. Whether he had any hand in the Calatrava name itself is another question, but the timing is fitting: the simple round dress watch was already one of Patek’s cornerstones. What it now had was a name worthy of the lineage, and he was in charge when it happened.
The Calatrava Today

The Calatrava Cross represented Patek Philippe itself. The Ref. 96 and its descendants came to represent perhaps the purest expression of the traditional Patek wristwatch. By eventually naming that family after the company’s emblem, Patek transformed Calatrava from the name of a medieval fortress, to an order, to a cross, to a corporate symbol, and finally to the name of its archetypal watch.
But the word didn’t stop there.
Decades later, as the Ref. 96 became the quintessential example of this particular style of watch, collectors, dealers, auction houses, and writers began applying Calatrava backward and eventually sideways to similar watches from other manufacturers. A simple round Longines from the 1940s became a “Longines Calatrava.” An old time-only IWC became an “IWC Calatrava.” The word had escaped Patek entirely.

Today, Calatrava gets used all over the place, whether correctly or not. It has become the Sharpie, Kleenex, or Post-it Note of the watch world: a proper name that has slowly become shorthand for an entire category. Search the vintage market and Calatrava now describes any number of thin, restrained, time-only dress watches from decades past, watches with no connection to Patek Philippe, the Ref. 96, the Calatrava Cross, or the medieval order that carried its name.
Which is a pretty remarkable journey for a word that started with an eighth-century Islamic fortress on the banks of the Guadiana. Nearly 1,200 years later, we’re using it to sell old watches on the internet.
