Constellation Sedna™ gold Master Chronometer 131.58.29.20.99.001

As part of an exquisite collection of timepieces, this watch combines the iconic Constellation design with a dazzling selection of 634 precious stones totalling 1.56 ct. The 29 mm case is crafted from 18K Sedna™ gold and is snow-paved with 108 full cut diamonds. Gripping to its sides are the legendary polished claws, along with a bezel that features Roman numerals in positive relief and 160 full cut diamonds. The astonishing attention to detail is continued on the 18K white gold dial, which is fully paved in a snow setting of 354 single cut diamonds. There is also an 18K Sedna™ gold Constellation star, and most beautifully, a circle of 12 baguette-cut ruby hour markers in 18K white gold holders. The watch is completed by a red leather strap on a polished 18K Sedna™ gold buckle. Behind the sapphire crystal on the caseback sits the OMEGA Co-Axial Master Chronometer Calibre 8703.
