Used Omega Speedmaster "MoonWatch" 42MM - 311.30.42.30.01.005

By Paul Altieri

The Speedmaster "Moon Watch" is to Omega as the Submariner is to Rolex and the Navitimer is to Breitling, a true icon of the brand. An impressive chronograph, the Speedmaster is equipped with a Tachymeter bezel and chronograph functions that can be used by the wearer to measure incredible speeds. It was because of these features that the Speedmaster was chosen as the watch of NASA's astronauts, resulting in its presence during all six lunar missions and earning it its impressive nickname "Moon Watch". While its history is certainly impressive, what makes the Moon Watch such a popular choice among collectors is the use of a versatile stainless steel finish and striking black dial and bezel. The newer pre-owned Omega that is presented here today features improved materials, such as a Hesalite crystal over the dial, a calibre 1861 mechanical movement, and brighter luminous material.

htThe Omega Speedmaster professional chronograph, or Moonwatch, is the master of precision timekeeping. Trusted by Nasa as a tool watch for Astronauts, the Omega Speedmaster has famously accompanied astronauts on six lunar missions. Its impressive chronograph function includes a seconds subdial, 30-minute subdial, 12-hour subdial, and central sweeping hand. Pushing the side pushers engages the chronograph function, allowing the wearer to use their Omega Speedmaster as a stopwatch. The case is also outfitted with a Tachymetric bezel that can be used to measure incredible speeds, a particularly useful function for astronauts and professional drivers. The case is waterproof up to 50 meters and outfitted with a Hesalite crystal. The Omega calibre 1861 movement beats within the case and boasts manual-winding and a 48-hour power reserve.tps://www.youtube.com/watch?v=BY9h4wqKbbk

    Beautiful Watch

    I've wanted a Moonwatch for over 20 years since I saw one in a space magazine in elementary school. I finally own one and couldn't be happier. Using the NATO strap until I can get several links removed from the metal band, but oddly enough I actual really like the NATO strap...

    Superb site and transaction, phenominal delivery time. Some slight confusion concerning the special discount at the time. I didn't receive it. No big deal I would not hesitate to purchase another rolex from Bob's ! ***
