Omega 311.30.42.30.01.006 (Pre-owned - Good) — USD 5,909 on eBay

The Omega Speedmaster Professional Moonwatch reference 311.30.42.30.01.006 represents a significant chapter in the enduring legacy of the "Moonwatch," Omega's most iconic timepiece. Produced between 2014 and 2021, this reference embodies the classic design and technical specifications that qualified the Speedmaster for all six lunar missions, making it a direct descendant of the watch worn by astronauts on the moon. Its continued adherence to the fundamental elements that defined the original makes it a cornerstone of any serious Omega collection. Crafted with a 42 mm stainless steel case, the watch maintains the distinctive silhouette and proportions that have been synonymous with the Speedmaster Professional for decades. The legendary black dial, with its contrasting white hands and indices, ensures optimal legibility, a critical aspect of its professional heritage. Water resistance is rated at 50 meters, consistent with its historical specifications as a robust tool watch. At the heart of the reference 311.30.42.30.01.006 beats the manual-winding Omega Caliber 1861. This cam-actuated chronograph movement is a direct descendant of the Caliber 861, which itself evolved from the original Caliber 321, and has powered the Speedmaster Professional for decades. Its reliability and serviceability are well-regarded, making it a beloved movement among enthusiasts. This specific period of production for the 311.30.42.30.01.006 places it as one of the final iterations of the mainline Speedmaster Professional to house the Caliber 1861 before Omega's subsequent transition to the Master Chronometer certified Caliber 3861. For collectors, the 311.30.42.30.01.006 holds particular appeal as a pure, traditional Moonwatch that captures the essence of its space-faring predecessors without modern technological updates. Its status as a "last of its kind" with the Caliber 1861, preceding the introduction of the 3861 movement, marks it as a distinct and highly sought-after reference that encapsulates the classic Speedmaster Professional experience.
