Produced between 1870 and 1920, the Duchess clock is collectible due to its exquisite design, rarity, and association with the renowned Seth Thomas Clock Company. Notable features of this model include the finely crafted brass movement, often adorned with engraved ornaments, and the beautifully designed pendulum bob, which adds a touch of grandeur to the overall aesthetic.
In addition to its visual appeal, the Duchess clock’s collectibility stems from its historical significance as an iconic piece from the golden age of American clockmaking.
