How it wears, by wrist size
Large but doable — the hesalite dome and flat caseback sit higher than the specs suggest. Try before buying.
The sweet spot — classic Moonwatch proportions.
Ideal; comfortable for a 42mm hand-wound chrono.
Proportionate and secure on the bracelet.
Buy or skip?
Editorial take: 9/10 — the romantic's Moonwatch, now at a discount to the new one.
This is the Moonwatch of moon-landing continuity: hesalite crystal, solid caseback, and the Cam-and-lever soul of the 1861. It lacks the new watch's anti-magnetism and bracelet, and the market has noticed — clean examples now undercut the current Sapphire Sandwich by a third. For a first Moonwatch bought pre-owned, this is the sweet spot.
- You want modern engineering — the 3861 generation is METAS-certified and anti-magnetic
- You want scratch-proof glass — hesalite scuffs (it also polishes out with Polywatch)
- You want water resistance — 50m, hand-wound crown, no swimming

Frequently asked questions
Is the Omega 311.30.42.30.01.005 discontinued?
Yes — production ended in 2021 when the Calibre 3861 generation (310.30.42.50.01.001) took over. As of our last check (2026-08-23) it is secondary-market only.
What is the difference between the 311.30.42.30.01.005 and the new 310.30.42.50.01.001?
Movement (1861 vs METAS-certified 3861), bracelet (the new one is dramatically better), dial details (step dial, applied logo on the new watch), and caseback engraving. The new one costs roughly $1,500–$2,500 more pre-owned.
Is the hesalite Moonwatch a good investment?
It holds a loyal value floor better than most Omegas, but it is not an appreciation play. Buy it for the history. Past performance is not a guarantee, and this is not financial advice.
Why hesalite instead of sapphire?
NASA heritage: acrylic does not shatter into floating fragments in zero gravity. It scratches easily but polishes out in minutes with Polywatch — and the warm dome distortion is half the Moonwatch charm.
What movement is in the 311.30.42.30.01.005?
The Omega Calibre 1861: a hand-wound cam-and-lever chronograph descended from the Lemania 1873, direct heir to the Calibre 321 that went to the Moon.
What is the lug-to-lug of this Moonwatch?
Approximately 48mm by editorial measurement on the 42mm case with 20mm lug width. Verify against manufacturer data if precision matters.
Where to buy safely
Not applicable — discontinued; the current 3861 generation is the boutique route.
The realistic route — deep supply means you can demand full sets (big box, straps, cards) at fair prices.
Occasionally fine for mint full sets; factor the buyer's premium.
Low-risk with normal precautions — verify serial, chronograph function, and hesalite condition before money moves.
