The seller represents this timepiece as being in very good condition. It includes a box, a Pictograms card, additional items, and open papers.
The Omega Speedmaster Dark Side of the Moon “Grey Side of the Moon” (311.93.44.51.99.001) features a 44.25mm grey ceramic case paired with a matching tachymeter bezel, both inspired by the lunar surface itself. Its stunning grey dial—crafted from lunar dust–toned 950 platinum—sets this model apart, offering a refined, almost ethereal sheen that echoes the moon’s texture. Two chronograph subdials at 3 and 9 o’clock, along with a date window at 6, ensure practical functionality within its celestial design. A sapphire window on the case back reveals Omega’s impressive 9300 Co-Axial movement, underscoring the technical mastery behind this piece. Completing the look is a grey alligator strap with matching stitching and a rich contrasting interior, secured by a branded pin buckle. This “Grey Side of the Moon” is one of the most striking interpretations of the Speedmaster line—elegant, modern, and unmistakably tied to Omega’s lunar heritage.
