Tiffany & Co. Revives Its 1893 Astronomical Clock

Some watchmaking creations pass through the ages without ever losing their power to fascinate. Others become true witnesses of History. The astronomical clock by Tiffany & Co. belongs to this second category.

To mark the 250th anniversary of the signing of the United States Declaration of Independence, Tiffany & Co. is once again unveiling a historic piece designed by the House for the 1893 World’s Columbian Exposition in Chicago. Restored over seven months in the Geneva watchmaking workshops of Tiffany & Co., this impressive astronomical clock now recovers its full technical, aesthetic and heritage dimension.

Its history is already exceptional. Its mechanics are even more so: it incorporates no fewer than 21 complications, most of them astronomical. Some have become extremely rare in contemporary watchmaking. One of them is even unique: the indication of the number of years elapsed since the independence of the United States.

In 2026, the mechanism thus displays « 250th ».

A spectacular way for Tiffany & Co. to bring watchmaking, astronomy and American history into dialogue.

A piece created for the World’s Columbian Exposition in Chicago

The year is 1893.

Chicago hosts the World’s Columbian Exposition, a major event intended to celebrate the 400th anniversary of Christopher Columbus’s arrival in America. Tiffany & Co. then chooses to present an extraordinary watchmaking achievement, designed to demonstrate the full extent of its expertise.

The making of this astronomical clock is placed under the direction of Joseph Lindauer, Master Clock Maker of Tiffany & Co. The House’s craftsmen work for more than two years to bring this genuine mechanical work of art to life.

Set in an imposing Louis XV style case, the clock stands eight feet tall, or nearly 2.5 meters.

Its casing draws on rich decoration made up of floral sculptures and marquetry. On the front, thirteen painted silver dials, ringed with gilt, are set into a frame enhanced with California mother-of-pearl.

But behind this spectacular appearance lies above all a mechanism of exceptional complexity.

Twenty-one complications gathered in a single clock

The Astronomical Clock by Tiffany & Co. does not merely tell the time.

Its 21 complications make it possible to follow different forms of time measurement, from the civil time we use daily to the astronomical phenomena directly linked to the movements of the celestial bodies.

This accumulation of functions constitutes today a remarkable testament to what mechanical watchmaking could achieve at the end of the 19th century.

Some indications are familiar, such as the hours and minutes or the perpetual calendar. Others are much rarer, or even practically absent from modern watchmaking.

And all contribute to the same aim: to represent time in its broadest dimension.

A true miniature astronomical observatory

On the upper dial, the Sun and the Moon appear in their respective apparent positions, against a decor depicting the sky.

Below this celestial representation is a horizon line giving rise to an evocation of the sea. It makes it possible to represent the tides at every hour.

The clock thus becomes far more than an instrument intended to measure time. It establishes a direct link between the mechanical movement and the phenomena observable in the sky.

Other dials complete this ensemble.

One of them is a perpetual calendar indicating in particular the signs of the zodiac, the month, the date, the day of the week, leap years as well as the Anno Domini.

Beside it, another dial represents a meridian divided into 24 parts and graduated from Greenwich. It also incorporates 31 of the world’s principal cities and makes it possible to know simultaneously the time of day or night in each of them thanks to a rotating plate.

A veritable temporal map of the world at a time when international travel and long-distance communications were undergoing spectacular development.

The Sun, the Moon and the celestial rhythms

The richness of the Astronomical Clock reveals itself even more when one looks at its astronomical indications.

The clock notably displays the apparent position of the Sun, the times of sunrise and sunset, as well as the apparent position of the Moon and its various phases.

It also indicates the tides thanks to the representation of the horizon located above the sea.

But Tiffany & Co. goes much further.

The mechanism makes it possible in particular to display the equation of time, that is, the difference between the 24-hour civil time and true solar time.

It also indicates the declination of the Sun, corresponding to the angle formed between the solar rays and the plane of the Earth’s equator, as well as the declination of the Moon, which depends notably on the inclination of its orbit.

These indications bear witness to an era when astronomical watchmaking still constituted a genuine laboratory for understanding time and the celestial cycles.

Complications that have become almost impossible to find

Some functions of this clock are particularly fascinating because they have virtually disappeared from modern watches and clocks.

Among them is the solar cycle, which positions the year within a 28-year cycle used to determine the distribution of the days of the week.

The clock also possesses the « Golden Numbers », used in calendars to determine the dates of the new moons within the 19-year metonic cycle.

Next comes the epact, which corresponds to the age of the ecclesiastical Moon on 1 January and which historically plays a role in the calculation of the date of Easter.

Finally, the dominical letter is a particularly rare complication intended to determine the day of the week corresponding to a given date.

These last three functions take on an added dimension when they are considered together.

The solar cycle, the dominical letters and the epact make it possible to determine the ecclesiastical full moon following the spring equinox. The date of Easter is then set on the first Sunday following this full moon.

A mechanism that therefore no longer merely measures the hours: it attempts to bring order to the great cycles of human, earthly and religious time.

A unique complication to celebrate America

But one indication truly sets this clock apart from all others.

Its mechanism makes it possible to display the number of years elapsed since 1776, the year of the independence of the United States.

This historic complication, described as unique, takes on a very particular resonance in 2026.

To mark the 250th anniversary of the signing of the Declaration of Independence, the clock displays « 250th ».

Time then becomes memory.

More than a century after its creation, this indication conceived by the watchmakers of Tiffany & Co. regains its full relevance. The mechanism designed at the end of the 19th century thus continues to count the years of American History.

Tiffany & Co., a little-known watchmaking history

This restoration also serves as a reminder of a sometimes forgotten dimension of the history of Tiffany & Co.: its longevity and its expertise in the field of watchmaking.

The House begins marketing watches and clocks as early as 1847.

In 1868, Tiffany & Co. opens an office as well as a watch assembly workshop in Geneva. A few years later, in 1874, the House establishes a manufacture in the heart of the Swiss watchmaking city.

On both sides of the Atlantic, its watchmakers and clockmakers then develop genuine technical expertise and file several patents linked to mechanical innovations.

The Astronomical Clock of 1893 is therefore part of an ancient watchmaking history deeply rooted in Tiffany & Co.’s desire to combine aesthetic creation, artisanal know-how and technical innovation.

Seven months to awaken a masterpiece

Acquired by Tiffany & Co. in 2025, the clock underwent a particularly meticulous restoration.

For seven months, the House’s Geneva watchmaking workshops worked to restore its mechanical operation while preserving its aesthetic integrity.

The objective was twofold: to recover a perfectly operational mechanism while respecting the appearance and the spirit of this historic creation.

This restoration work takes on its full meaning today, since the clock regains a place in the contemporary history of Tiffany & Co.

After its unveiling on 3 July 2026, it will be presented to the public at the Landmark, the Tiffany & Co. flagship located at 727 Fifth Avenue in New York.

A clock that has become living memory

It is rare for a watchmaking creation to be able to tell so many things at once.

The Astronomical Clock by Tiffany & Co. tells the story of a House which, as early as the 19th century, aspired to master the most complex disciplines of watchmaking. It also tells of the evolution of the measurement of time, the astronomical knowledge of its era and the fascination for the great celestial cycles.

But above all it tells an American story.

In 2026, as the United States celebrates 250 years since the signing of its Declaration of Independence, this clock designed in 1893 returns to the spotlight with an indication that seems to have been imagined for this precise moment.

« 250th ».

Two digits and three letters that on their own sum up the extraordinary dialogue between mechanics and History.

With the restoration of this exceptional piece, Tiffany & Co. does not merely preserve an old object. The House reactivates a part of its watchmaking heritage and reminds us that certain mechanical creations are not intended solely to measure time.

They are there to preserve its memory.
