Omega · Family: Speedmaster
The Omega Speedmaster Professional Moonwatch Co-Axial Master Chronometer ref. 310.32.42.30.01.002 is the 42mm steel manual-wind chronograph powered by Calibre 3861, with a Co-Axial escapement and METAS Master Chronometer certification. Cazador has no verified price observations yet (0 recorded). Its standout detail is the sapphire caseback, which exposes the finished Calibre 3861 versus the closed steel-back executions in the same Professional line.

The Speedmaster Professional is the chronograph Omega consistently ties to the 'Moonwatch' nickname, rooted in its documented association with NASA's crewed spaceflight program. Per widely documented brand history, NASA qualified the Speedmaster Professional in 1965 for use on all manned space missions after subjecting it to a battery of thermal, shock, and vacuum tests [UNVERIFIED: exact test protocol details, dates, and names of those involved are not part of this source]. That origin is what gives the model its popular name and much of its collector appeal.
Reference 310.32.42.30.01.002 sits within the current Moonwatch generation built around Calibre 3861: a manual-winding chronograph with a Co-Axial escapement, the technology Omega introduced to reduce friction between escapement components and extend service intervals. On top of that movement, Omega adds Co-Axial Master Chronometer certification, independently validated by METAS (Metrology and Testing Institute of Switzerland), which tests the fully cased watch — not the bare movement — for precision, resistance to magnetic fields up to 15,000 gauss, and water resistance.
What sets this particular execution apart within the Moonwatch family is its transparent sapphire caseback, which exposes the finishing and construction of Calibre 3861 — including its balance bridge and manual-wind mechanics visible from the back — versus the closed steel-caseback variants Omega also offers in the same Professional line. This configuration typically appeals to buyers who want to see the movement without giving up the 42mm steel case or the classic Moonwatch dial and bezel identity.
Beyond these verifiable points, any details about specific astronauts, individual Apollo-program missions, or in-flight anecdotes tied to this exact reference are not part of the documentation available in this source and fall outside the scope of this fiche [UNVERIFIED].
The nickname comes from its documented association with NASA's crewed spaceflight program, which qualified the Speedmaster Professional in 1965 for use on all manned missions. Specific mission and astronaut details tied to this exact reference are not documented in this source.
We don't yet have enough verified market data (0 observations) to publish a reliable price range. We avoid estimating figures without sourced data; this section activates once at least 5 verified PricePoints exist.
The main documented difference is the caseback: this execution carries a transparent sapphire back that exposes Calibre 3861, versus the closed steel-caseback variants in the same Professional line.
It's an independent certification from Switzerland's METAS that tests the fully cased watch, not just the bare movement, for precision, resistance to magnetic fields up to 15,000 gauss, and water resistance — a step beyond standard COSC certification.
It's a manual-winding movement with a Co-Axial escapement, continuing the Speedmaster Professional's tradition as a mechanical chronograph without an automatic oscillating mass.
Approximately 50 hours [UNVERIFIED: exact minute-level figure not confirmed for this specific reference in available source data].
Based on available information it remains in current catalog [UNVERIFIED: exact catalog status not reconfirmed as of this fiche's publication date]. We'll update this once we can confirm it against a direct source.
No, it's not built for diving: the Moonwatch family carries a reference water resistance around 50 meters, suitable for daily wear but not for serious diving [UNVERIFIED: exact figure not line-item reconfirmed for this reference].
