Brass drive weights with lead, from the long-case clock by Ahasuerus Fromanteel, London, United Kingdom, 1660-1665

The Fromanteel family produced the first pendulum clocks in England, following the visit of Fromanteel’s son John to Holland (Netherlands). He learned to make these new clocks from Salomon Coster who had an agreement with Christiaan Huygens to use his idea. Clocks now became accurate enough to have minute hands.
