Antique Seth Thomas Office Calendar No. 7 Clock
Jan 2020 – 46 Antique American Clocks Seth Thomas “Office Calendar No. 7”, 1888. The second-smallest Office Calendar, at 26.5 inches (behind the No. 3 “Peanut”). This one is very original. The glasses and hands are old, including the original calendar hand; the dials may have been repainted long ago as they are just too good to still be original paint, but they show a lot of age; the calendar roller paper covers are very dark, and the walnut veneer case shows no repairs and has all the decorative buttons. This one is time-only with a signed ST movement that is running effortlessly. The pendulum bob is a replacement. The calendar day is advancing but the date needs adjustment. Good labels inside, and a date stamp on the back (1888). About all you could ask for. The last one Horton’s sold was in July of 2018 for $610.

Seth Thomas “Office Calendar No. 7”, C. 1878.
Rosewood veneer case is 26.5″ high, with decorative attached buttons, top, bottom, and middle. The case is very similar to their No. 4 and No. 6 models. This case is almost perfect, no bad veneer, no repairs, all original. Key lock on the side. Two labels inside the case, the one on the door says the clock and calendar were set to running November 1, 1878. Original dials have not been repainted and have very little paint loss; however, years ago someone put a coat of varnish or wax on the dials. It has held the paint very good, but it also darkened them somewhat and gives the impression there are brush marks. They aren’t bad, and since the case is so nice I would sure live with the dials. 8 day, spring, striking hours on a large brass bell. Perpetual calendar is functioning and clock is running.

Seth Thomas “Office Calendar No. 7”, C. 1878.
This No. 7 in some ways is a better clock than #64, but the rosewood veneer on #64 always looks better to me. This walnut veneer case is very nice, still with the original finish, a tiny veneer chip or two, scuffed on the bottom of the door, but no harm. This door has a hook on the side, where #64 has a key lock on the side. The biggest negative is that the case apparently split slightly around the lower hinge. It hasn’t been tinkered with and is not bad as is. I probably would not do anything. Dials look very good, color matches, but top dial was repainted at some time. Two excellent full labels. The one on the door says the clock was set to running on August 1, 1878. The case is 26.5″ high. Movement is 8 day, strikes hours on a large brass bell, perpetual calendar is working properly. Ly-Seth Thomas #67; Ly-Calendar #608.

C.1880, Seth Thomas Clock Co., “Office Calendar No. 7”, 8-day calendar timepiece, as-found, less veneer on bezels.
The rosewood veneered case is otherwise fine with original finish on the sides and old finish on the front. Both painted dials are original, but someone has done some poor repair to the numbers 6-7-8-9 and there is some minor paint loss on the lower dial. The hands are original and the calendar wheels are rather clean for their age. Our estimate reflects the missing veneer. Still photogenic; legible label inside door has some wear. Height 26.5 inches
