Speedmaster Professional Moonwatch
the "Moonwatch"
The watch NASA actually flight-qualified: 42mm steel, hand-wound Caliber 3861, METAS-certified, still shipped with Hesalite instead of sapphire by design.

Every watch that claims heritage owes a debt to the one that actually has government paperwork: NASA flight-qualified the Speedmaster Professional in 1965, and Omega has spent six decades declining to modernize the parts of the case that made it pass.
The current reference, 310.30.42.50.01.001, runs the manual wind Caliber 3861: 42mm across, 13.54mm thick, 47.5mm lug to lug, per Omega’s own spec sheet rather than the numbers enthusiasts round to. METAS Master Chronometer certification means the movement is tested to 0/+5 seconds a day and rated antimagnetic to 15,000 gauss, on top of a 50-hour reserve that assumes you wind it yourself every morning. Water resistance sits at a modest 50 meters. This is a chronograph built for a spacesuit, not a dive computer.
The trade Omega actually makes is with the crystal, not the bracelet. Hesalite is acrylic, softer than the sapphire fitted to this reference’s costlier sibling, and it will pick up hairline scratches from a rough cuff in a way mineral or sapphire would resist. Omega keeps selling it anyway because a whole subculture of owners polishes their own crystals with toothpaste and calls it maintenance, and it is, genuinely, the crystal that flew. The caseback is the quieter concession: solid steel with the Seahorse medallion, not sapphire, so a movement that earned an actual METAS certificate stays permanently out of sight.
None of that changes the recommendation so much as it costs it. At $6,650 to $7,800 depending on how hard the dealer negotiates, you are paying a large premium over a manual wind chronograph with 50 meters of water resistance and an acrylic crystal, specs a $200 field watch would beat on paper alone. You are also buying the only watch on this page with documented spaceflight history and a service network most of the field can’t match. If you want a steel sport watch with a lower price and a clasp that does more of the comfort work, the Black Bay 58 sits right there in the rail below.
