Which effect increased navigational accuracy during oceanic voyages when marine chronometers replaced sandglasses?

💡 Explanation

When marine chronometers replaced sandglasses, accurate timekeeping allowed precise determination of longitude by comparing local time with Greenwich Mean Time because the Earth rotates 15 degrees per hour. Therefore longitude was better determined, rather than stellar navigation, latitude calculation or magnetic corrections, which rely on different principles.
