The Omega Speedmaster X-33, introduced in 1998 as a modern-day Moonwatch (now 'Mars Watch'), came with a high-tech titanium case and an analog/digital movement with a specified set of functions. Reference 3990.50.36, a first-generation piece, is fitted with a red Kevlar strap and a folding buckle, which distinguishes it from the 3990.50.41 that has a pin buckle.
