How it wears, by wrist size
Large but classic — 42mm with a 47.5mm lug-to-lug is manageable. The 3861 case wears slimmer than the old 1861.
The sweet spot — this is the proportion the Moonwatch was born with.
Ideal; flat and secure on the new bracelet.
Proportionate; consider keeping it on the bracelet rather than a NATO for balance.
Buy or skip?
Editorial take: 9/10 — the Moonwatch for people who look at movements.
The Sapphire Sandwich costs more than the hesalite version and gives you scratch-proof glass plus a view of the best hand-wound chronograph Omega has ever made — METAS-certified, anti-magnetic, and finally with a bracelet worthy of the watch. If the romantic Moonwatch ritual matters more than movement-watching, the hesalite 310.30.42.50.01.001 saves you money.
- You want the 'flown' purity — the hesalite/solid-back version is the NASA-spec configuration
- You want water resistance — 50m and a hand-wound crown mean this is not a swim watch
- You forget to wind watches — hand-wound means daily ritual

Frequently asked questions
Is the Omega 310.30.42.50.01.002 discontinued?
No. As of our last check (2026-08-23) the Sapphire Sandwich Moonwatch is in current production.
What is the difference between the .001 and .002 Moonwatch?
Crystals and caseback: the .001 keeps the traditional hesalite (acrylic) front and solid caseback; the .002 ('Sapphire Sandwich') uses sapphire front and back so you can see the Calibre 3861. Same movement, same case.
Is the Speedmaster Moonwatch a good investment?
Standard-production Moonwatches depreciate normally — buy it for the history and the movement, not the return. Past performance is not a guarantee, and this is not financial advice.
What movement is in the 310.30.42.50.01.002?
The Omega Calibre 3861: hand-wound chronograph with Co-Axial escapement, 50-hour reserve, METAS Master Chronometer certified including 15,000-gauss magnetic resistance.
Is the 3861 better than the old 1861?
Objectively yes — METAS certification, anti-magnetism, longer reserve, finer finishing. Subjectively, the 1861 has half a century of moon-landing lineage. Both are legitimate Moonwatches.
What is the lug-to-lug of the Moonwatch 42mm?
Approximately 47.5mm by editorial measurement on the 42mm case with 20mm lug width. Verify against manufacturer data if precision matters.
Can I swim with the Sapphire Sandwich?
No — 50m water resistance and a hand-wound crown mean splashes only. Moonwatch first, sports watch second.
Where to buy safely
Safe route with the 5-year warranty and the full box set of straps; ADs sometimes negotiate.
The value route — pre-owned Sapphire Sandwiches run $6,200–$7,800 with full sets.
Skip for a current-production Moonwatch — premiums make no sense here.
Low-risk with normal precautions — verify serial, chronograph reset, and the full strap set before money moves.
