ARNOLD & SON EIGHT-DAY 43MM WATCH

Back in the 18th century, John Arnold delivered marine chronometers with reliability and down-to-the-second precision needed by navigators to determine longitude on the high seas. The Eight-Day combines these features with a high-performance movement and two of the hallmarks of the antic marine chronometers: the power reserve at 12 o’clock and small seconds at 6 o’clock.
