42mm brushed and polished stainless steel case with a 48-hour power reserve, water resistant to 100 feet / 30 meters. Scratch-resistant sapphire crystal glass with a solid screw-down caseback crisply stamped with the iconic Speedmaster Hippocampus medallion, a solid 18K white gold fluted tachymeter scale bezel, and the classic asymmetrical case architecture built for premium flight utility. Exceptional, aristocratic on-wrist presence thanks to its creamy ivory dial, luxury heat-blued steel accents, and an elegant quad-register tracking layout.

Sophisticated mid-2000s complication model housing a legendary space-heritage hand-wound mechanical engine, featuring iconic blued-steel "Broad Arrow" hands, matching applied blue luminous hourglass markers, a dedicated pointer date tracking dial flanking an integrated photo-realistic moon phase window at 12 o'clock, and crisp blue chronograph tracking elements.

Full Set, with original red Omega leather presentation box, cream leather cardholder wallet, operating instructions manual, pictogram card, and original international warranty card.
