Graham Watches Celebrates 300th Anniversary of the Orrery
Thursday - 04 July 2013
The Geo.Graham Tourbillon Orrery is a limited edition of just 20 pieces, and features the Moon, Earth, Mars and the Sun based on a 300-year calendar. The Moon is made of rhodium; the Earth is blue sapphire; Mars is a ruby; and the Sun is represented by a rose gold hand-engraved Tourbillon bridge with two Phoenix heads, inspired by the decoration used by George Graham.
The watch has an 18kt rose gold case with a 48 mm diameter. It is powered by the Graham calibre G1800 high precision mechanical movement, exclusively made by Christophe Claret with Haute Horlogerie finishing and circular Côtes de Genève decoration.
The black dial features three scales: the hours and minutes scale, Gregorian calendar (365.25 days) and Zodiac scale (12 astrological signs). Earth indicates the date and zodiac sign. The watch has off-centre skeleton hands with black SuperLumiNova coating.
The Tourbillon Orrery has a domed sapphire crystal with anti-reflective coating on both sides, and a see-through sapphire crystal case back. The case back features a 100-year scale, Moon and Mars correction indicators, and a hand-engraved serial number. 'Geo.Graham Tourbillon Orrery' is inscribed on the dial at 4 o'clock.
The timepiece comes with a hand-sewn black croco strap with an 18kt rose gold buckle.
