Since 1897, Chelsea Clock has kept time for the White House, the U.S. Navy, and generations of American homes. Now, as the nation marks its 250th year, we are honored to introduce the Columbia Collection — three timepieces designed to commemorate this singular moment in history.

At the heart of each mechanical clock beats our 12E movement, an American-made caliber we are releasing for the first time in nearly 20 years. The solid brass case is encircled by 250 individually etched rays on the bezel — one for each year of the republic — while the America 250 logo is engraved on the back plate, hidden like a private inscription meant for those who look closely. Each clock rests on a hand-finished wooden base. (Designed in partnership with Observatory.)

The Columbia Collection is available in three expressions. The 4.5" Columbia and 6" Columbia house the 12E mechanical movement and are produced entirely in the United States. The Columbia Medallion offers the full artistry of the collection in quartz — the same etched bezel, the same America 250 engraving, the same considered design — every detail intact, every engraving present.

This is a limited edition release. When they are gone, they are gone.
