This 100% brass bell with a lacquer finish is a replica of the ship's clock that seamen would strike in a half-hour sequence based on the four-hour ship's watch system. The end of the first half hour was marked by one bell, the end of the first hour was two bells, the end of the first 1-1/2 hours was three bells, etc. Eight bells mark the end of a four-hour watch. Eight bells are struck six times in a 24-hour period: at noon, 4 p.m., 8 p.m., midnight, 4 a.m. and 8 a.m.
