About This Watch
The Omega Speedmaster Moonwatch Professional with sapphire crystal offers a modern interpretation of the legendary Moonwatch. This version features sapphire crystal on both the front and exhibition caseback, allowing the wearer to admire the beautifully finished caliber 3861 movement. The bezel is upgraded to a polished black ceramic ring with a tachymeter scale filled with white enamel, replacing the aluminum insert of the Hesalite model. This combination of modern materials with the classic Moonwatch design creates a more refined, scratch-resistant timepiece while maintaining the same iconic silhouette. The sapphire crystal provides superior scratch resistance and clarity compared to the traditional Hesalite, making it popular among those who prioritize daily wearability. The Master Chronometer certification ensures accuracy of 0/+5 seconds per day and resistance to magnetic fields of 15,000 gauss. Whether you choose Hesalite or sapphire is one of the great debates in watch collecting — the sapphire version offers practicality and a view of the movement, while sacrificing some of the vintage charm that makes the Hesalite so beloved.
