OMEGA Speedmaster Dark Side of the Moon: How the Ceramic Legend is Refined with the 2025 Update

OMEGA’s Fine-Tuning: The Dark Side of the Moon Series Evolves Since its debut at Baselworld in 2013, the Omega Speedmaster Dark Side of the Moon (DSotM) has stood as a pinnacle of the brand’s technological mastery and ceramic application in modern luxury watchmaking. This bold, entirely ceramic rendition of the legendary Moonwatch quickly became a collector favorite, embracing the theme of the "far side of the Moon." Marking the start of its fall releases, Omega's 2025 update significantly renews the DSotM series. Comprising a total of seven new references (four core models with various strap options), this lineup adheres to the established design while introducing crucial technical and aesthetic improvements. The update primarily focuses on transitioning the ceramic Speedmaster to the latest Master Chronometer calibres and enhancing its overall ergonomics through case refinement. Size Unchanged, Ergonomics Enhanced Despite widespread anticipation for a change, the case diameter remains consistent across the new models at 44.25 mm. However, the previous generation’s thickness, which often exceeded 16.14 mm, has been subtly reduced to 15.09 mm on the automatic models using the Calibre 9900. This slight reduction offers a noticeably better fit and presence on the wrist. All new DSotM models continue to offer 50 meters of water resistance. Here is a breakdown of the four main models comprising the new "Dark Side of the Moon" collection: 1. Dark Side of the Moon Automatic (Dark/White, Calibre 9900) The most conventional and legible member of the series, this model pairs the black ceramic case and bezel with crisp white markings and indications. Calibre: Omega Co-Axial Master Chronometer 9900 (Automatic, 60-hour power reserve, METAS certified). Design: Features the dual-register layout (with combined chronograph minutes and hours at 3 o’clock) and a date display at 6 o’clock. This model maintains the spirit of its predecessor (the Calibre 9300 version) while offering a slightly slimmer profile and the superior performance of a modern Master Chronometer certified movement. 2. Grey Side of the Moon Apollo 8 (Skeletonized, Manual, Calibre 3869) This is the most visually and thematically powerful model in the series. Inspired by astronaut Jim Lovell’s observation that “the moon is essentially grey,” it is executed entirely in grey ceramic. Calibre: Omega Co-Axial Master Chronometer 3869 (Manual-winding, 50-hour power reserve). Key Feature: At 12.97 mm, it is the thinnest model in the series. Both the dial and movement are skeletonized using laser ablation technology to replicate the Moon’s surface texture. This reference will be particularly appealing to collectors who missed out on previous Apollo 8 DSotM editions. 3. Black Black Automatic (Calibre 9900) Embodying pure stealth and monochrome elegance, this version preserves the ethos of the former "Black Black" model. Even the markings and indices are designed to be as subdued as possible, visible mainly by lume activation. Calibre: Co-Axial Master Chronometer 9900 (Automatic). Design: An updated and slightly thinner iteration of the previous Calibre 9300 version, perfect for those who favor the ultimate stealth aesthetic. 4. Black Red Manual (Calibre 9908) This is arguably the collection's most eye-catching, yet technically "nerdy," variant. The predominantly black theme is dramatically broken up only by the strategic use of red on the central chronograph seconds hand and the "Speedmaster" text on the dial. Calibre: Co-Axial Master Chronometer 9908 (Manual-winding, 60-hour power reserve). Feature: Unlike the automatic 9900, it omits the date function. This minimalist, manual-winding aesthetic strongly appeals to purists of the traditional Speedmaster. The Industry’s Lingering Question: Why No Smaller Case? With this quartet, Omega has pushed the technical limits of the existing DSotM platform, creating a more contemporary collection. The slimmer cases and updated Master Chronometer calibres are robust arguments for an upgrade. Yet, one enduring request from the watch community, persistent for over a decade, remains unanswered: A smaller case diameter. Considering the Speedmaster Professional sits at 42 mm, the 44.25 mm ceramic case remains a substantial presence, particularly challenging for smaller wrists. The influx of a new, younger audience—partially thanks to the massive success of models like the Moonswatch—is eager to see the cool and bold aesthetic of the DSotM in a more accessible size (i.e., 40-42 mm). In conclusion, the 2025 Dark Side of the Moon update delivers a powerful technical evolution. While the refinements, new finishes, and upgraded calibres will entice dedicated fans of the format, the broader watch market and the next generation of collectors are still keenly awaiting a long-overdue ergonomic downsizing of the ceramic Speedmaster in the near future.
