Two and a half centuries of independence. Two hundred and fifty years of a republic built, tested, defended, and carried forward by every generation that came before us. The 250th anniversary of the United States is not merely a milestone — it is a unique moment in time. It deserves to be honored with intention. It deserves to be held.

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.

Introducing the Columbia Collection. Three limited edition 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.
