C.1905, Seth Thomas, “Regulator No. 7” wall clock
(short version) in excellent original condition. This is an interesting clock, in that it has an 80 beat movement on which the pendulum rides around 4″ off the bottom of the case, which to me makes it a more pleasant appearing clock than the regular 72 beat movement, on which the view of the pendulum is restricted behind the door. The movement is original to the case and there are no spare holes for any of the hardware; movement appears similar to that used in a No. 2. The beat scale has always been mounted in the high spot it occupies. The case retains original finish, nicely polished; the dial has been professionally re-blacked over the original white surface (has nice crazing), and with original hands, pendulum, hardware, etc. Height 45″

C.1905, Seth Thomas, Thomaston, Conn, “Regulator No. 7” Long, in walnut, in excellent original condition.
The only thing that keeps this from being outstanding is some flaking on the dial. The finish has nice patina, a little dull, would rub to a sheen unless you prefer it as is. This clock has the large No.62 movement with cut pinions and maintaining power. Note also this is the desirable long case version. The weight has split the bottom board, but it has been properly repaired. We sold the cousin to this clock on year ago, lot 304 for $9750+12%. Although this should fare as well, our estimate is conservative. Any Seth Thomas collector would be pleased with this clock. Height 48″
