This collectable 18th century industrial design features a 30 minute hourglass made of bronze and wood. Ship's hourglasses were calibrated to the half hours of the ship's watch, and if the helmsman didn't turn the glass too early it actually doubled in defining longitude. Navigators tried to keep count of the hours; the galleons wrecked on the Western Australian reefs remind us of the perils of incorrectly kept time.
