The work carried out to this historically important year duration table clock started in 2004 when Tom Scott purchased the movement on the advice of Richard Garnier. The originally finished clock would have represented Tompion’s most-ambitious achievement ever and would have been commissioned by Prince George in a conscious surpassing of William III’s year-going Mostyn clock, being of vastly superior complication. Tom’s vision, and the dedicated research by, and under the direction of Garnier, started the long journey of restoration using the finest craftsmen available.

It was not completed until after Tom’s death in 2012, so Tom did not see the end result of his passion and drive, not to mention his funding, but he undoubtedly saved this horological masterpiece, breathing new life into its near-forgotten past.
