In nautical terminology, the time a sentry stands watch or a ship's crew is on duty, equal to 4 hours on both land and sea. At sea, the evening watch is often divided into two shorter watches called dog watches. During dog watches, sailors' watch assignments rotate through the day instead of falling at the same hours every day. Watches at sea are divided into 8 bells (4 bells for dog watches).
