Many luxury watches look similar and fail to stand out, especially when you want something distinctive yet historically significant.

The Omega Speedmaster Moonwatch "Grey Side of the Moon" 311.63.44.51.99.001 offers a rare combination of space heritage, cutting-edge materials, and an authentic meteorite dial—crafted from ancient extraterrestrial stone.

You get a bold, technically advanced chronograph that carries the legendary Speedmaster DNA, enhanced with modern ceramic engineering and 18K Sedna™ gold details. It’s built for adventure, refined for formal wear, and designed to make a lasting impression.

Encased in 44.25mm of grey ceramic, this 2024 pre-owned example (excellent condition) features a grey ceramic meteorite dial, acid-etched to reveal a unique pattern—meaning no two dials are identical. The 18K Sedna™ gold bezel with silicon nitride ring and brushed OMEGA Ceragold™ tachymeter scale adds warmth and contrast to the monochromatic design.

Inside beats OMEGA’s Co-Axial Calibre 9300 automatic chronograph movement, visible through a sapphire crystal caseback, delivering precision and a 60-hour power reserve. Presented on a grey leather strap with a foldover clasp, this timepiece includes the box and papers.
