The story
After the great sea clocks came the sea watch — the marine timekeeper shrunk toward the pocket, precise enough to carry a ship's longitude in a case a captain could hold. This period engraving of a Berthoud sea watch shows the movement the way the eighteenth century preferred its triumphs: open, symmetrical, and slightly grander than life. Between Harrison's H4 and the chronometers of the next century, this is the shape the solution settled into.
