Dials on Antique Seth Thomas 30 Hour Brass Movement Weight Clocks

Summary of dial types in chronological order:

• Wood or embossed metal (outer ring and chapter ring embossed), dots for minute marks, two rings drawn outside minute marks;
• Embossed metal (outer ring and chapter ring embossed), dots for minute marks, one ring drawn outside minute marks;
• Embossed metal (chapter ring embossed), dots for minute marks (one example reported to me 11-23-06).
• Embossed metal (chapter ring embossed), lines for minute marks, with corner decorations;
• Embossed metal (chapter ring embossed), no corner decorations;
• Embossed metal (chapter ring embossed), no corner decorations, ST logo in circle
• Flat metal, printed instead of drawn, printed corner decorations.

The very earliest dials, ca. 1842 - 43 have two characteristics:

• The numerals 3, 4 and 8 taper narrower toward the center of the dial;
• The winding holes are small, around 8.2 mm.

It is interesting that the earliest dials on the Seth Thomas one day brass clock were painted metal. Why did wooden dials appear for a short time around 1845? It may be that they were left over stock from the wooden movement clocks, which were discontinued in 1844 or 1845. This is the theory that Richard Tjarks and I have come up with, please let me know if you can provide any information about this. If you have a Seth Thomas wooden movement ogee clock, so we can compare the dials and case.

Late dial.

An article in the NAWCC Bulletin states that William B. Fenn, a dial and tablet painter, worked almost exclusively for Seth Thomas from 1840 to about 1863. It would be interesting to know if he painted some of the corner decoration in the earlier dials illustrated above.
