Seth Thomas Clock Co. “World”, ca. 1900. ST made this model in both a 15-day and 30-day version. Both versions used a No. 86 movement mounted on an iron bracket, with
the same 21.5-inch pendulum length, and were housed in identical cases. There are two clues that may allow you to distinguish
a 15-day from a 30-day: A movement marked ‘86W’, as found here, is a 30-day movement (Ly, Seth Thomas Clocks & Watches,
Vol. 2, page 959), whereas 15-day movements usually are not marked, and use the original No. 86 movement (no letter designation). In addition, 30-day clocks usually have “THIRTY DAY” printed on the dial below the number 6, but this may be lost on a repainted or
replaced dial. The 15-day World was marketed from 1896–1921, but ST did not make the 30-day version until the 1920’s. Here, the 32-inch oak case has a clean, old finish; the dial glass is modern, the lower door glass earlier. The painted metal
dial is clean but worn; it is not designated as a thirty day. The ST 86W movement, signed and time-only, double-wind, is running. The heavy pendulum bob and stick look right, there is a worn beat scale, and no label or date on the back. AAC sold a similar
example last summer for $300. $150–$300.
