Omega Speedmaster Moonwatch Muunfueizu 3576.50 — USD 6,143

The Omega Speedmaster Moon Phase reference 3576.50 stands as a distinguished variant within the venerable Speedmaster collection, offering a sophisticated blend of the iconic manual-wind chronograph with astronomical complications. Emerging from an era that saw the Speedmaster line diversify beyond its "Moonwatch" origins, this reference maintains the spirit of its manual-wind Professional siblings while introducing a more intricate horological display. Crafted in stainless steel with a matching bracelet, it presents the familiar robust case and black tachymeter bezel synonymous with the Speedmaster's racing and space heritage. Distinguishing the 3576.50 are its specific dial layout and complications. The classic black dial incorporates three subsidiary registers for chronograph functions, but uniquely features a combined moon phase and pointer date indicator positioned prominently at 12 o'clock. This integration provides a visually arresting and highly functional display, setting it apart from standard Professional models and the automatic Speedmaster Date variants. The watch maintains the asymmetrical case design of the Speedmaster Professional, ensuring its unmistakable profile. Powering the Speedmaster Moon Phase 3576.50 is a manual-wind chronograph movement, specifically the Omega Calibre 1866. This calibre is a direct descendant of the legendary Calibre 1861 (itself based on the Lemania 1873), augmented with modules for the moon phase and date complications. Delivering a reliable 48-hour power reserve, the movement embodies the traditional mechanical artistry cherished by collectors, offering an engaging winding experience akin to the original Moonwatch. For collectors, the reference 3576.50 represents a desirable intersection of tradition and complication. It appeals to those who appreciate the manual-wind ethos of the Speedmaster Professional but seek the added charm and utility of an astronomical display. Its relatively less common status compared to the standard Professional models, combined with its distinctive dial architecture and direct lineage to Omega's storied chronograph movements, ensures its significance within the broader Speedmaster universe.
