Movement

Etched in time.

Introducing the Columbia Collection — three handcrafted timepieces forged in brass, designed with Observatory to honor exceptional history.

A new chapter in a long Chelsea tradition.

The Columbia Collection began with America’s 250th anniversary, a milestone that called for more than a commemorative object. Chelsea worked with designers Cutter Hutton and Ayako Takase of Observatory to create a clock worthy of the occasion and designed to be passed down for generations to follow.

Founded in 1897 and still manufacturing in Chelsea, Massachusetts, Chelsea Clock is America's oldest and largest maker of luxury mechanical clocks and marine timepieces. For nearly 130 years, our clocks have kept time aboard U.S. Navy vessels, in the offices of presidents, across every branch of the military, and in the homes of generations of Americans who understood that a well-made clock is not a decoration — it is a record of the hours that mattered.

Columbia Collection Details

Introducing the Columbia Collection. Three handcrafted timepieces, each conceived with the gravity this anniversary demands and built to the standard Chelsea has held since 1897.

At the heart of each mechanical clock beats our 12E movement, — hand-built from more than 125 brass and steel parts, requiring more than a month to produce, and available for the first time in nearly a quarter century. Every movement is hand-assembled by craftspeople who each average nearly two decades of experience, then repeatedly tested for accuracy, precision, and quality at our factory in Chelsea, Massachusetts. The case of the Columbia is finished with a precision-machined surface, highlighting its solid forged brass origins. The face of the clock is encircled by 250 individually etched rays on the bezel — one for each year of the republic. A custom silvered dial with a unique face design is paired with a matching set of custom black hands. The casing is mounted to a hand-finished, solid wood architectural base. On the back of the clock, the officially licensed America 250™ seal can be engraved, defining this design's moment in time.

250 Ray Bezel

250 etched rays encircle the dial, each marking a year of the American story. Together, a solid-brass sunburst and a quiet nod to the anniversary behind the collection.

Custom Dial & Custom Black Hands

Designed exclusively for the Columbia Collection, a new hand and face design evokes Chelsea's heritage while looking forward.

Custom Engrave Back Plate

A smooth back plate, ready for a personal engraved inscription. The most enduring gifts are the ones that carry a name, a date, or a few words worth keeping.

The 12E Movement — American-Made, Hand-Assembled

More than 125 brass and steel parts. More than a month to build and test. Assembled by craftspeople averaging nearly two decades of experience. The 12E is not a component — it is an American engineering marvel at the heart of the clock.

Individually Serialized

Each mechanical clock carries its own serial number — and can be personalized — making every piece as singular as the moment it commemorates.

Design

The Columbia Collection is a collaboration of the Chelsea engineers and designers Cutter Hutton and Ayako Takase. The team designed the Columbia clocks to celebrate the masterful craftsmanship, quality materials, and remarkable engineering that define Chelsea Clocks while artfully reflecting on our nation’s past and looking towards its future. Hutton & Takase’s studio, Observatory, is located in Providence, Rhode Island, where the two teach at the Rhode Island School of Design.

Forged in Brass. Finished by hand.

The Columbia Collection is made for the generations ahead. Handcrafted in Chelsea, Massachusetts.
