Lewis-Burwell Double Dial
Perpetual Calendar Clock
(ca. 1867)

This is a fine example of a weight-driven calendar clock produced for Bristol, Connecticut,
dealers L.F. and W.W. Carter (circa 1867).  Collectors frequently refer to this
double dial clock as the “Lewis No. 2” model.

The rosewood veneered case with grain-painted bezels houses an eight-day-running,
weight-driven timepiece movement and an early perpetual calendar mechanism invented
by Benjamin B. Lewis.  Elias Burwell purchased rights to manufacture Lewis’
patent mechanism (circa 1864-1867).
 



(Item #AC-3)

(ca. 31-1/2" H x 15-1/2" W x
4-1/4" D)

This calendar mechanism, described as the “Y” variant based on the configuration of
its back plate, automatically compensates for differences in the length of the months, including the Leap Year.

Thus, it is “perpetual.”

Both movements are original to the case. The clock retains its original hands, pendulum rod, weights, and case hardware. 

The painted 12” diameter time dial is original to the case and was professionally cleaned and restored.
