The full plate gilt keywind fusee movement features Harrison's maintaining power, ensuring precision and accuracy. The plain cock is adorned with a diamond endstone set in blue steel, adding an elegant touch. The compensation balance, with its heavy blue steel and brass laminated rims, is secured by screws to slender brass arms. A helical blue steel hairspring completes the impeccable craftsmanship.
The chronometer escapement is a masterpiece in itself, with an Earnshaw spring detent dovetailed into a gilt foot. The escape pivots are equipped with endstones, enhancing the accuracy of the movement. The white enamel dial is signed and numbered, featuring Roman numerals and gold hands. A subsidiary seconds dial adds to the functionality of the timepiece.

John Barwise was a highly esteemed watchmaker of his time and was selected by the Board of Longitude to assess the chronometers made by John Arnold and Thomas Earnshaw. This chronometer is a testament to his skill and expertise. The casemaker Thomas Hardy, known for his work on Arnold chronometers, crafted the consular case with his mark "TH" in a rectangle.
In conclusion, this early 19th century chronometer by Barwise is a remarkable piece of horological history. Its exquisite craftsmanship, combined with its historical significance, make it a truly special timepiece.
