The Adamantine process was Patented in 1880 & Seth Thomas began to produce them in 1882 (per our research). Adamantine is a celluloid coating or veneer used over the clock case wood to mimic marble & rich grained woods or sometimes were done in black & other colors. The advantage to the process was that it allowed for less expensive production & made the clock much lighter for self display as well. The marble & metal based clocks could weigh over 20 lbs, this clock is under 10 lbs.
This clock has the 89-C movement & workings that are very clean for its age & it runs well. There is writing on the inside instruction tag that indicates the clock may have been serviced in 1994, but we are not 100% certain. We simply gently oiled ports which were already clean & otherwise left clock alone & as found.
It keeps good time, has key & chimes the number on the hour & once on the half hour. It has run consistently for several weeks & keeps fairly accurate time. Always use clock on a flat level surface for proper functioning. There are some care instructions on the inside label as well, although we have found over the years that the regulator adjustments take less adjusting than suggested for speeding up or slowing down the clocks. The clock case is in very good to excellent condition, but not perfect.The are a few places where the coating on surface has wear and some minor touch ups (as photoed), but overall it looks great. The clock face plate is nice and uniform in color as well, but a little off white. The scroll design on lower clock face is original but many owners will apply paint (white, gold, black) in the pattern for a more pronounced look, we just left it as we found it. We took multiple pictures from all sides of clock for your consideration and you can use zoom feature as well. A key is included, but the one in pictures will be swapped out for a double ended key that fits both the regulator and clock winding slots.
We just got the key after we shot pictures. We obtained the clock from an antique collector's private sale. Not sure of the exact date this clock was made, as it is not dated. But that is our best estimate.This does appear to be the rarest of the Adamantine Column clocks from what we could tell. You can find many of the 2-6 column but not so many 8's. Let us know if you have nay questions. We can attest this clock was running very well.
