A glazed table clock known as ‘T45’ by Anthony Randall, England, completed 1998. This clock incorporates an accurate reconstruction of parts, from the centre wheel onwards, of the mechanisms of John Harrison’s H4 and H5 timekeepers. The ‘T’ in the name references the two tensator mainsprings which drive the mechanism, and enable it to run for 8 days on a single wind, with a very constant driving force. The centre wheel drives a train remontoire via an internally cut third wheel. The remontoire rewinds an additional small spring, which provides the energy to drive the escapement, which is mounted on a platform at the top of the clock. Donated to the Clockmakers' Charity by the maker, Anthony Randall. Clockmakers' Museum No. 1535
