The Omega Speedmaster X-33 debuted in 1998 as a modern-day Moonwatch, now the 'Mars Watch', featuring a high-tech titanium case and an analog/digital movement with a special set of functions. The second generation, released in 2001, received minor updates. Reference 3291.50.00 is from this second generation, easily identified by its matte bezel insert and distinct crown.
