Notes

This clock was converted to balance spring from bristle regulator and minute hand added in the early eighteenth century. This improvement was well carried out with minimum disturbance of the movement. It is interesting to point out that the replacement balance fitted at the time, was made from the back plate of an oignon watch, and still bears the signature "J.F. Dreuz à Paris. A fine astronomical masterpiece clock by the same maker, is in the Time Museum, Rockford, Illinois.
