The Dials

Duff & Sollace

 Seth Thomas offered a remarkable selection of glass-enamel dials in different styles and fonts, manufactured by the local firm of  Duff & Sollace until late in 1897, when a fire destroyed their factory. 


After the fire, the company used Swiss-made dials for all of the named grades and lower-grade models. Single-sunk dials, two pieces of copper soldered together, were installed on just about every Model 1 through 4. Double-sunk dials are quite rare, especially those with Gothic fonts, and were used only on the highest grades of the Model 5. Fancy dials using gold or silver filigree on top of a colored base were pressed and are also very hard to find. No genuine Ferguson dials have been reported so far.

Their Factory

The Duff & Sollace Dial Co was organized on November 19, 1895 in Thomaston, Connecticut by George Duff with capital stock of $5,000. This new venture, led by Joseph Sollace, began supplying enamel dials for the nearby Seth Thomas watch factory using a small machine shop owned by Charles Smith at the corner of Center and Litchfield Streets in Thomaston, which burned down on the night of October 25, 1897.

Dial Feet Locations

An 18-size dial will fit either open-face or hunting configurations. They came with only two dial feet at 13 and 45 minutes prior to 1900, when a much-needed third foot was added near the 34-minute-mark.

The Metal and Embossed Dials

Painted metal dial were an aftermarket item from the Roaring Twenties, when the Art-Deco style was in full swing. They were evidently designed to replace damaged porcelain originals, and are quite rare.

The Contract Dials

Most of the contract grades came with matching dials (not including private labels), and the company offered replacements for the same cost as the standard dials. The train motif was common and used on the RR Special, Engine Special, and Trainmen's Special.
