The **Omega Speedmaster Professional Moonwatch Ref. 311.30.42.30.01.006** stands as one of the most iconic chronographs in horological history. Known as the **“Moonwatch,”** it was the first watch worn on the Moon, earning its place in human exploration.

Its **42 mm stainless steel case** is inspired by the original 4th-generation Speedmaster worn on Apollo 11. The watch features a **black dial** with luminous hour markers and **three sub-dials** for 30-minute, 12-hour, and small-seconds counters. The **hesalite crystal** protects the dial, while the **sapphire crystal caseback** allows a full view of the movement — hence the “sapphire sandwich” nickname.

Inside beats the **Omega Calibre 1863**, a manual-winding chronograph movement derived from the legendary Calibre 1861, itself a direct descendant of the Calibre 321 used during the Apollo era. This rhodium-finished movement showcases classic chronograph architecture and delivers impeccable reliability with a **48-hour power reserve**.

The **tachymeter bezel**, engraved on black aluminum, underscores the watch’s racing origins. Water-resistant to **50 meters**, the watch is mounted on a solid **stainless steel bracelet** with a folding clasp. The caseback is engraved with “**Flight-Qualified by NASA for All Manned Space Missions**” and “**The First Watch Worn on the Moon**.”

The 311.30.42.30.01.006 is not just a watch — it’s a piece of history, combining timeless design, mechanical excellence, and a legacy that transcends generations.
