Omega Speedmaster Moonwatch Moon to Mars 3577.50.00 Discontinued 2005 [Preowned]Overview The Omega Speedmaster Moonwatch "Moon to Mars" (ref. 3577. 50) is a tribute to both past lunar achievements and future Martian exploration. Introduced in 2004, this special edition features a striking dial with sub dials representing Earth, the Moon, and Mars in vivid colors. Though the sub dials were initially met with mixed reactions due to their grainy, photo realistic designs, they have become a defining feature of this unique watch.
