In the summer of 1913 the Seth Thomas Clock Company issued Centennial Medals to celebrate the one-hundredth anniversary of the original founding of the company in 1813.  The medals were designed by Seth Thomas jr., the great-grandson of the founder of the Seth Thomas Clock Company. The Centennial Medals were two and one half inches (2 1/2”) in diameter, struck in bronze with a gold finish.  The obverse displays a portrait of Seth Thomas, in relief. Around the edge it reads “To Commemorate The 100th Year of Seth Thomas Clock Co”.  At the sides of the portrait “ Seth Thomas” and “1785-1859” is inscribed. On the reverse there is a figure representing Father Time holding a pendulum in his right hand swinging over a scale marked 1813 - 1913.  The pendulum ball bears the Seth Thomas trade mark. In Father Time’s left hand is a scythe.  To his right is an hourglass.

Later that year on September 1st of 1913 the Seth Thomas Clock Company released its Catalog No. 701 “Seth Thomas Watch Movements”. Catalog No. 701 was also marked as the “Centennial Edition” Trade Price List. 

Within the 1913 Centennial Edition Trade Price List Seth Thomas introduced “Seth Thomas ‘Centennial’ Open-Face Watches”, 7-jewel high grade movements in three sizes. All of the movements were pendant set, utilized the Breguet hairspring, and came cased and timed from the factory.
