 Old Style Navigator Compass  Parts (1965-1980)

The original Navigator series compass from E.S. Ritchie & Sons was first manufactured in 1965. The dome measures 4-1/4" in diameter. The Navigator takes approximately 25 ounces of compass oil to fill it completely. It was made as you see it on this page until it was modified in 1980. At that time the the dome and oring were modified. The Modified Navigator was manufactured until 1984. If you are ordering parts from this page be sure that the oring on your compass is mounted on the outside of the dome. If it is under the dome than you need to see the parts diagram for the Modified Old Style Navigator. Click on the diagram to identify the parts that you need.
