About the Seth Thomas “Ding Dong Strike No. 3” Clock
The Seth Thomas “Ding Dong Strike No. 3” clock, manufactured around 1913, showcases a unique and distinctive design with its case made from Brazilian onyx adamantine. This rare and exquisite piece measures approximately 14 inches wide and nearly 12 inches high, preserving a near-perfect condition despite the passage of time.
The original features of this clock include a flat glass in the sash, correct hands, and an adamantine type cream dial that bears the signature of Seth Thomas Clock Co. The dial also displays the distinctive “Ding Dong Strike” name, indicating its origin from the renowned American manufacturer.
The clock’s ornaments and sash were originally adorned with dull, gold plating, although this has tarnished over time, particularly noticeable on the mat. The clock features a large back board, two large bells similar to those found in Sonora Chime cases, and an 8-day movement that is signed by Seth Thomas. While the pendulum bob is correct, there are suspicions that the back cover may not be original.
This piece can be found detailed on Ly-Seth Thomas, page 446, providing a valuable reference for collectors interested in this unique and intriguing timepiece.

Seth Thomas Clock Co. “Ding Dong Strike No. 3”, ca 1913.
Rare case made of Brazilian onyx adamantine. The case is 14″ wide, almost 12″ high, and in near perfect condition. ST said that the sash, mat, and ornaments were “dull, gold plated”. Maybe when original, now dull and tarnished, particularly the mat. Flat glass in the sash, correct hands and perfect adamantine type cream dial. The dial is signed, “Seth Thomas / Ding Dong Strike / Manufactured in the United States of America”. Large back board, two large bells placed similar to those in Sonora Chime cases, 8 day movement is signed, and has the correct pendulum bob. I suspect the back cover is not original.
