Sinclair Harding Moonphase Sea Clock 1829-325

The Sinclair Harding Moonphase Sea Clock 1829-325 is a distinguished tribute to the age of maritime exploration and the pursuit of the longitude problem at sea. Inspired by the broader historical challenge of determining longitude, it reflects the development of John Harrison’s pioneering marine chronometers alongside earlier astronomical approaches such as the lunar distance method associated with Edmund Halley. At its centre, a hand-painted moonphase dial individually signed and numbered by artist Keith Warrington offers a poetic interpretation of this celestial tradition, each piece incorporating a hidden initial and date that ensures every clock is uniquely detailed. Crafted predominantly within Sinclair Harding’s workshops, the clock unites modern precision with traditional finishing techniques, resulting in an object of enduring character and quiet refinement. A celebration of British craftsmanship, it honours the artistry and ingenuity that shaped one of the most pivotal chapters in horological history.
