Omega Constellation Co-Axial Watch, 35 mm, Steel and 18 Carat Gold, Diamond Markers, Automatic, Warranty 2016

An Omega Constellation Co-Axial in steel and 18 carat gold, with a gold-coloured dial, diamond hour markers, a Roman numeral bezel, a date window and a display case back.

The Piece

Omega was founded in 1848 by Louis Brandt in La Chaux-de-Fonds, Switzerland, and its Constellation line has carried a star-and-observatory emblem on the case back since the 1950s.

The case is 35 mm, with a gold bezel engraved with Roman numerals, gold claw guards at the crown and a steel and gold bracelet with a folding clasp bearing the Omega emblem. The gold-coloured dial is signed Omega Constellation and Co-Axial Chronometer, with diamond hour markers, a star beneath the lettering and a date window at three. The display case back shows the automatic movement.

The watch is in very good order. Its previous owner finds the dial and hands clean, with slight scratches on the crystal and slight scratches and small dents on the case, bezel and bracelet, and on a flat timegrapher test it loses about 18 seconds a day, which is offered as a rough guide only. The wrist circumference is about 16.5 cm with no spare links. The warranty card is dated March 2016, and the last photograph shows it with the precious stones certificate and pictograms card.
