The short answer
The Omega Speedmaster Moonwatch (Professional) is a hand-wound chronograph made over a long period in several configurations. The current generation uses calibre 3861 (Co-Axial Master Chronometer, from 2021); its predecessor is the calibre 1861, made until 2021. The current 3861 is offered in two configurations: a hesalite front crystal with a solid steel caseback, or a sapphire front crystal with a sapphire display caseback — the crystal and caseback go together by version. Fair Vintage confirms the generation and version from the watch, grades the condition, values period-appropriate accessories, and gives a free, no-obligation valuation — all by post from Bedfordshire, with insured postage and payment by bank transfer within 72 hours of you accepting.
The current Moonwatch generation uses the hand-wound calibre 3861 (Co-Axial Master Chronometer), introduced in 2021. Its predecessor is the hand-wound calibre 1861, made until 2021. Both are manual-wind chronographs, but they are different generations, and the market treats them differently.
The current 3861 Moonwatch is offered in two configurations that pair specific parts together. The crystal and caseback go together by version — a hesalite front comes with the solid caseback, and the sapphire front with the display caseback.

A note on older examples. Across the Moonwatch's long history, the bracelet design, box, presentation set and included accessories have changed by period. Don't assume every Moonwatch came with the same bracelet or the same package — an earlier example may differ from a current one, and we assess yours as it is.
The generation (3861 vs 1861) and version (hesalite vs sapphire), case and bracelet condition, whether the watch has been polished, dial and hand originality, and how complete and period-appropriate the accessories are.
For a Moonwatch, buyers value a period-correct presentation box, the warranty card, and period-appropriate accessories — including any extra strap or tools where that particular generation included them. Matching the accessories to the era of the watch matters more here than on most models.
We buy Moonwatches without box and papers; we confirm the generation and version from the watch and reflect any missing items in the offer.

Distinguishing a 3861 from an 1861, and a hesalite/solid-caseback watch from a sapphire/display-caseback one, has a real bearing on value. For more on how references and nicknames shape an offer, see our guide to luxury watch resale value in the UK.

The 3861 (from 2021) is the current Co-Axial Master Chronometer; the 1861 is its predecessor, made until 2021. Both are hand-wound.
What's the difference between the hesalite and sapphire versions?
The hesalite version has an acrylic front crystal and a solid steel caseback; the sapphire version has a sapphire crystal and a sapphire display caseback.
Which is worth more, hesalite or sapphire?
They appeal to different buyers; we value each on its own condition and configuration rather than assuming one is always higher.
Did all Moonwatches come with the same box and accessories?
No — the presentation set and accessories have changed by period, so we assess what's period-appropriate for your example.
Is my Moonwatch automatic?
No — the Moonwatch Professional is hand-wound, both in the 3861 and 1861 generations.
Can I sell without the box and papers?
Yes — we confirm the generation and version from the watch and reflect any missing items in the valuation.
