Port Chalmers Historic Society member Harry Woods said watching crews from AmberTrax and Stark Bros install the recently redesigned timeball about noon yesterday at Flagstaff Lookout was the culmination of about three years’ planning for the four society members pushing the plan.
"Once I get that ball on, I’ll be able to have a restful sleep at night," Mr Woods said.
"There’s a lot of maritime history there to see - after all those hours, it’s come together."
The 120kg marine-grade stainless steel time-signalling device, now obsolete, was made in Christchurch by Stark Bros.
It was painted black to increase its visibility from a long distance, Mr Woods said.
He had tested it and could see the flagstaff from as far away as St Leonards, nearly 6km from the lookout.
He and fellow historic society members Norman Ledgerwood, Garry Bain and Warner Gardner were also working on information panels for a planned October 3 opening, Mr Woods said.
From that date, just as it did for a decade in the late 19th century, the timeball would rise then drop to mark 1pm every day.
The original timeball at Port Chalmers was used daily from 1867 to 1877 so ships’ officers could set their chronometers, used in navigation.
In April 1882, the service was reinstated as a weekly service following a petition from 11 shipmasters, a history of the timeball provided to the Otago Daily Times outlines.
Although the timeball then fell into disuse, it remained on the flagstaff until 1970, when the flagstaff underwent rebuilding.
The society raised $50,000 for the project.
