Omega Speedmaster Moonwatch Professional 310.30.42.50.01.001
Known as Moonwatch Professional, Hesalite (Caliber 3861)
This is the Hesalite version of the current Omega Speedmaster Moonwatch Professional, the reference that replaced the long-running 311.30.42.30.01.005 in January 2021. It is the closest thing Omega makes to the watch that went to the Moon: 42mm stainless steel, a domed Hesalite crystal instead of sapphire, a solid engraved caseback, and the asymmetric case profile Omega brought back with this generation. The big change over the outgoing model is inside. The old hand-wound caliber 1861 is gone, replaced by the caliber 3861, a Co-Axial Master Chronometer certified by METAS. So you keep the manual-wind, three-register, tri-compax Speedmaster you know, but now with a co-axial escapement and 15,000 gauss magnetic resistance. If a collector says just Moonwatch and means the everyday, wear-it-anywhere, no-worries steel Speed, this is the reference they mean. We buy and sell it every week on 47th Street.
Produced: Introduced January 2021 and still in current production as of 2026. This is the fifth-generation Moonwatch and the first to carry the caliber 3861 in place of the caliber 1861. The .001 Hesalite reference remains the entry point to the current Moonwatch line.

Market & Value
This is one of the most liquid luxury watches in the world, which is exactly why the numbers matter. US list is $7,800 for the Hesalite on bracelet. The sapphire-sandwich version, reference 310.30.42.50.01.002 with a display caseback, lists higher at $9,000. On the secondary market the Hesalite .001 has settled well under retail: pre-owned examples in good shape have traded in roughly the $5,000 to $6,000 range through 2026, with fresh 'brand new' dealer listings on Chrono24 clustering around $6,750 to $6,850. WatchCharts has shown the model firming up over the past year rather than sliding further, so the bleed off the 2021 launch highs looks like it has mostly played out. Two practical takeaways for a buyer or seller. First, unlike the steel Rolex sports models, you do not need to chase the gray market on a Moonwatch; supply is healthy and you can usually buy the exact spec you want. Second, that same availability caps upside, so this is a watch you buy to wear and keep, not to flip. When we write a check on one, we price to real transacted numbers, not to list.
What to Know Before You Buy
A few things separate this reference from the ones around it and from the model it replaced. The Hesalite crystal is the point, not a compromise. It is the historically correct material, it takes a knock without shattering, and light scuffs polish out with Polywatch in a minute. If you want a clear display caseback and a scratch-proof sapphire crystal front and back, you want the .002, and you pay $9,000 list for it. The caliber 3861 is the real story here. The co-axial escapement and the Master Chronometer certification mean this Speedmaster keeps time to a tighter daily rate than the old 1861 and shrugs off magnetic fields that would have stopped the previous movement cold. Watch the details that tell you it is the current generation: the step dial, the Broad Arrow hands, the dot-over-90 bezel, and the box-style Hesalite crystal. The five-arch bracelet with the comfort-release clasp is also new to this generation and is a genuine upgrade over the flat 1998-style bracelet on the outgoing model. On condition, because the Hesalite is soft, expect surface marks on any pre-owned example; those are cosmetic and cheap to address. What you actually inspect for value is bracelet stretch, sharp versus rounded lugs, and a full set with the correct dual box and both bracelet and NATO strap.
