Speedmaster 'Grey Side of the Moon'

The Omega Speedmaster 'Grey Side of the Moon' takes its inspiration from lunar exploration, channeling the mystique of the moon’s surface into a striking ceramic chronograph. Unlike the classic Speedmaster Professional, this model features a 44.3mm case crafted entirely from grey ceramic, giving it a unique matte sheen and impressive scratch resistance. Its design pays homage to the original Moonwatch but adds a contemporary edge through materials and finishing, making it a standout in the Speedmaster lineup for those seeking something beyond steel or gold variants.

This reference, 311.93.44.51.99.001, is powered by Omega’s in-house Caliber 9300, an automatic movement with a column-wheel chronograph and silicon balance spring, providing both accuracy and a 60-hour power reserve. The sapphire crystal caseback reveals the beautifully finished movement, a detail that collectors appreciate. Water resistance is rated at 50 meters, suitable for daily wear but not intended as a dive watch.

Price variation is driven by condition, completeness (box and papers), and whether the watch features the original ceramic buckle and leather strap—replacements can affect value. Early pieces with the meteorite dial variant command a premium over the standard sandblasted platinum dial. The 'Grey Side' is less common than the 'Dark Side' or 'White Side,' so expect fewer examples on the market. When buying, confirm the ceramic case is free of chips or cracks, as repairs are costly and replacements are not always possible.
