A diamond-paved bezel frames the natural green aventurine dial of this 29 mm Constellation, reference 131.28.29.20.99.001. Its case combines stainless steel with 18K Sedna™ gold, shaped with the collection's half-moon facets and claws, while a shimmering green alligator leather strap echoes the stone. The date is shown at 6 o'clock.

On the dial, hands and hour markers in 18K Sedna™ gold sit alongside a matching OMEGA logo and Constellation star. The self-winding calibre 8700 is a Co-Axial Master Chronometer certified by METAS, resistant to 15,000 gauss, with a silicon balance spring and 50 hours of power reserve. The strap fastens with a stainless steel pin buckle; water resistance is 50 metres.
