Overview
The Omega Speedmaster Grey Side of the Moon, reference 311.93.44.51.99.001, is a full-ceramic interpretation of the iconic Speedmaster silhouette, rendered entirely in a cohesive grey palette. Its 44.25 mm case is crafted from grey ceramic, a material prized for its scratch resistance and distinctive matte-satin aesthetic. Paired with a matching grey dial and powered by the in-house Co-Axial calibre 9300, it represents one of the more technically ambitious expressions within the broader Speedmaster family.
History
The Grey Side of the Moon was introduced in 2014 as part of Omega's expanding "Side of the Moon" sub-family, which explored the use of advanced ceramic case construction across the Speedmaster line. The reference built on the foundation laid by the earlier Dark Side of the Moon, substituting that model's black ceramic for a lighter, cool-toned grey ceramic throughout. Production continued until 2021, giving the reference a meaningful run during a period when Omega was actively investing in both in-house movement development and exotic case materials. Collectors have noted the model as a significant milestone in demonstrating how far ceramic finishing techniques had advanced within Swiss watchmaking.
Notable points
- The 44.25 mm case, lugs, and crown are all fashioned from grey ceramic, making the construction notably uniform in both material and colour.
- Calibre 9300 is an in-house Co-Axial movement featuring a column-wheel chronograph mechanism and a silicon balance spring, representing a high point in Omega's manufacture development.
- The monochromatic grey dial continues the case's tonal theme, with subdials and indices integrated without disrupting the overall visual harmony.
- The 'Side of the Moon' designation places this reference in a distinct Speedmaster sub-family defined by full ceramic cases, separate from the aluminium-bezel Professional line.
- Produced from 2014 to 2021, the reference enjoyed a sustained production period that allowed it to become well established among collectors of modern Speedmaster variants.
