THE MYSTERIES OF WATCHMAKING HISTORY
Part 2
CRIME, DISAPPEARANCE, REBIRTH AND THE ANATOMY OF A MASTERPIECE
If the genesis of Breguet No. 160 represents the pinnacle of human ingenuity in an aristocratic setting, its later journey belongs to a far more unpredictable narrative — one in which the object ceases to be merely a technical artefact and becomes the protagonist of an almost literary story. Over the course of the 20th century, the so-called Marie Antoinette becomes a symbol of collecting, of obsession and, ultimately, of the vulnerability of cultural heritage.
The watch that had survived the French Revolution, the death of the woman for whom it was intended and the passing of generations would come to face a danger of an entirely different nature: modern crime.
The Museum and the Illusion of Security
In the 20th century, Breguet No. 160 became part of the prestigious collection of Sir David Lionel Salomons, one of the most influential collectors and scholars of the work of Abraham-Louis Breguet. The collection, later donated, went on display at the L.A. Mayer Museum for Islamic Art in Jerusalem — an institution that, despite its name, houses one of the most important collections of classical watchmaking in the world.
For decades the watch remained there, seemingly safe, part of a museum narrative that presented it as the absolute masterpiece of historical engineering. That security, however, would prove illusory.
Seen in retrospect, the problem was not merely technical but conceptual: museum security at the time was prepared for conventional theft, not for meticulous operations carried out by highly specialised individuals.
The 1983 Heist: Criminal Precision
In the early hours of 15 April 1983, the museum was the target of a burglary whose execution was closer to a surgical operation than to a traditional robbery. The man responsible, Na’aman Diller, was no impulsive criminal but a methodical, patient and technically competent individual.
Diller entered the museum without arousing suspicion, disabled security systems and opened display cases thought to be impregnable. His choice of pieces reveals deep knowledge: he did not simply take objects of monetary value, but pieces of exceptional historical and horological importance — among them, Breguet No. 160.
What is most intriguing is not the success of the theft, but its logic. Unlike jewellery or gold, a watch such as the Marie Antoinette cannot be sold easily. It is too well known, too unique. This raises a fundamental question: what was the real motive?
The hypotheses include:
Pathological collecting — possession as an end in itself;
Long-term investment, waiting for future circumstances in which to sell;
or a form of intellectual challenge — the theft as proof of ability.
Whatever the motive, the result was devastating: the disappearance of one of the greatest icons of world watchmaking.
The Disappearance: When an Object Becomes Myth
For the next 24 years, the whereabouts of Breguet No. 160 remained completely unknown. No sign at auctions, no identified attempt at a clandestine sale, no credible lead.
This absolute silence had a curious effect: the watch ceased to be merely a missing object and became a contemporary myth.
In its physical absence, the narrative grew. Experts debated its fate:
had it been dismantled to conceal its identity?
was it hidden in an inaccessible private collection?
had it been destroyed by accident or neglect?
This period is particularly significant because it reveals something profound about the symbolic value of watchmaking: a watch may disappear physically, but it remains present in the collective imagination.
The Replica as an Act of Resistance: Breguet No. 1160
Faced with the disappearance of the original, the house of Breguet, under the leadership of Nicolas G. Hayek, took a decision that, at the time, seemed almost audacious: to reconstruct the Marie Antoinette without access to the watch itself.
This project — the Breguet No. 1160 — is in itself an extraordinary achievement. Based on historical drawings, descriptions and incomplete documentation, it required a hybrid approach combining technical archaeology and modern engineering.
What is at stake here is not merely replicating an object, but reconstructing an 18th-century thought process.
The team had to answer fundamental questions:
How did Breguet organise the movement internally?
What mechanical tolerances did he use?
How did he balance energy and precision across so many simultaneous complications?
The replica, completed in 2008, became a manifesto: watchmaking is not only the preservation of the past — it is also its intellectual re-creation.
The Rediscovery: The Return of the Impossible
In 2007, in a development worthy of a detective novel, the story took an unexpected turn. After the death of Diller, his widow contacted the authorities and revealed the existence of safes containing the stolen objects.
Among them, intact, was Breguet No. 160.
The impact of this discovery cannot be overstated. After more than two decades of absence, the watch returned to the public domain — not as a ruin, but as a working, well-preserved piece.
This moment represents something rare: a complete historical restitution.
Whereas many stolen artefacts are recovered in a deteriorated state, the Marie Antoinette returned practically unscathed, as if it had been placed in temporal suspension.
Mechanical Anatomy: An In-Depth Reading
With the watch accessible once again, it became possible to study it with modern tools. The analysis confirms what had already been suspected: No. 160 is not merely complex — it is structurally innovative.
Energy architecture
One of the greatest challenges in grand complication watches is energy management. Every additional function consumes power. In No. 160, Breguet devised a system in which energy is distributed in an almost organic way, avoiding excessive losses.
Integration of complications
Unlike later watches, in which complications are added as modules, No. 160 features native integration. Everything is part of a single, coherent system.
Precision vs. complexity
There is always a trade-off between complexity and precision. Breguet managed to minimise this conflict through innovative solutions, including low-friction materials and optimised geometries.
The third dimension
The movement is not flat. It is three-dimensional, almost architectural. This approach anticipates solutions that would only become common much later.
Cultural Significance: An Object That Survives History
Breguet No. 160 is more than an exceptional watch. It is an artefact that has lived through:
the fall of a monarchy,
the transformation of Europe,
the evolution of mechanical science,
and one of the most intriguing crimes of the 20th century.
Few objects manage to accumulate so many layers of meaning.
In my view, this watch represents something profoundly human: the attempt to create a perfect and lasting object in an intrinsically unstable world.
And perhaps that is why it continues to fascinate.
Between Time and Eternity
The journey of the Marie Antoinette shows that certain objects transcend their original function. From an instrument for measuring time, the watch becomes a witness to history itself.
Its survival — not only physical but symbolic — prompts an essential reflection: what makes an object truly valuable?
It is not just the gold, nor the mechanical complexity.
It is the history it carries.
Breguet No. 160 does not measure only hours. It measures centuries.
