The smallest of the ships bells. We offer four sizes of bells, petite to large, for beach house or boat... The helmsman rings the ships bell for every half hour of the four-hour ships watch.

One bell - One ring (say 12:30)... Two bells - Two rings (say 1 PM)... etc. until... Eight bells - Eight rings (4PM). AM-Living bells are made of heavy solid brass, handmade and sand-cast with bronze finish. The chunky hand knotted lanyard offers years of use. A true nautical heirloom offering clear & solid sounds.
