Honolulu Hawaii USA Horizontal Dial 278
The dial is a raised horizontal circle 18 inches in diameter. The nearly inch-wide brass gnomon supports a raised relief globe, with the Hawaiian Islands uppermost to accurately show which part of the world is in sunlight. The dial has hour lines and a ring of 5-minute marks. Hours are numbered from 6 until 18. Cardinal points and magnetic north are indicated. Dial shows some signs of deterioration. Designer Ginnosuke Ohara is a dialist with Japan's Research Institute for Sundials. The dial base is a mushroom design of concrete about 40 inches high and 40 inches in diameter. A time capsule is located in the base, to be opened in 2030.
Honolulu Hawaii USA Dial 291
Bronze. Outer circle has flame-shaped knobs projecting from rim. Indicator or axis cuts band diagonally, terminating in oval projection on lower side. Gift of Mrs. Theodore A. Cooke. This dial is no longer on display at the museum. When an enquiry was made in May 2002, none of the staff knew of the dial's existence until an elderly lady in the gift shop knew it was in storage. The lady was a grand daughter of Mrs. Cooke.
Honolulu Hawaii USA Equatorial Dial 340
As of May 2012, this dial was removed from display by museum staff. Bronze equatorial dial 20, inches in diameter. The dial is outlined by an ornate ring tilted in the plane of the polar axis with extending flames representing the sun. A gnomon rod bisects this ring. The dial base is a statue of the Hawaiian mythological figure Maui snaring the sun, Kala, with ropes to snare the sun. The dial itself is a semicircular portion of an equatorial ring with inscribed hour lines and raised Roman numerals. The dial has been exhibited in various museums in San Diego, San Francisco, Seattle and Vancouver before permanent installation at the Bishop Museum in Honolulu. Gnomon and equatorial ring appear misaligned for 21 degree latitude. The museum is will correct the dial in the near future.
Honolulu Hawaii USA Vertical Declining Dial 481
An elegant vertical declining and reclining dial built on the sloping face of a large lava boulder. Total size of the dial is 4 1/2 x 6 feet and uses a half-inch thick copper gnomon 6 x 10 inches. Hour lines and numerals at 9, 12, and 3 are of brass. The dial is corrected for longitude and was designed to fit its deep valley location and orientation of the boulder. Tradition holds that these rocks have spirits and must be treated with respect.
Kaneohe Hawaii USA Armillary Dial 543
A 32-inch diameter bronze armillary dial with extensive Polynesian-themed motif. An integral plaque provides corrections for EOT and longitude within HST. The armillary includes ten bronze rings: horizon; solstitial colure (meridian); equinoctial (equator); Tropic of Cancer; Tropic of Capricorn; Arctic circle; Antarctic circle; "prime vertical circle" perpendicular to the meridian circle and horizon that spans from east to zenith to west; equinoctial colure perpendicular to meridian circle and equator passing through the north and south poles; and an "upright ring" inscribed with Zodiacal signs between the prime vertical and equator.
Kaneohe Hawaii USA Horizontal Dial 715
A 12 inch diameter (perhaps bronze) horizontal dial with hour lines and half-hour marks and Roman hour numerals. Inscription area is heavily corroded. Dial rests on a mortared marble stone pedestal. This may be a commercial stock dial and the design may be flawed as the gnomon root appears to be north of the 6 AM - 6 PM line.
Pearl City, Oahu Hawaii USA Horizontal Dial 535
A 28 foot stone horizontal dial with 8 foot high black wood and fiberglass gnomon located in a children's Sundial Garden. Hour markers are Roman numerals cast into concrete blocks. Dial is screened by koa and lonomea trees.
