Omega Speedmaster 310.30.42.50.01.002 - Exhibition Caseback - New - Full Set

The Omega Speedmaster Professional Moonwatch reference 310.30.42.50.01.002, introduced in 2021, represents the most recent evolution of the legendary Speedmaster line — a watch forever linked to humankind's greatest achievement: the Moon landing. While embracing modern advancements in materials and movement technology, this reference remains fully faithful to the heritage and aesthetics that have made the Speedmaster one of the most revered chronographs in horological history. Encased in a 42 mm stainless steel case with the signature twisted lugs and asymmetrical design first introduced in the 1960s, the watch preserves the timeless Moonwatch profile. The matte black stepped dial features applied Super-LumiNova hour markers for optimal legibility, paired with the classic tri-compax chronograph layout that has defined the model for over half a century. The bezel, crafted in anodized aluminum, retains the vintage-correct 'dot over 90' tachymeter scale — a detail deeply appreciated by collectors for its historical authenticity. This version distinguishes itself from its sibling, the Hesalite-crystal model (ref. 310.30.42.50.01.001), through its use of sapphire crystal on both sides: a domed sapphire on the front for superior scratch resistance and a sapphire exhibition caseback revealing the beautifully finished manual-wind movement inside. This dual-crystal configuration has earned the affectionate nickname "Sapphire Sandwich" among enthusiasts. At its heart beats the Omega Co-Axial Master Chronometer Caliber 3861, the latest evolution of the storied 1861. This movement introduces Omega's proprietary Co-Axial escapement and Master Chronometer certification, ensuring magnetic resistance up to 15,000 gauss, improved accuracy, and enhanced reliability — all while maintaining the manual-winding character of the original Moonwatch. The newly redesigned stainless steel bracelet features a tapered profile and polished central links, offering improved comfort and a refined aesthetic that complements the watch's balanced proportions. Originally sold in 2024, this example remains in new condition and is offered complete with its original full set. A perfect blend of heritage and innovation, the 310.30.42.50.01.002 continues the Speedmaster's unmatched legacy as a chronograph of precision, endurance, and timeless design — equally at home in space or on Earth.
