Omega Speedmaster 3576.50.00: A Detailed Examination
The Omega Speedmaster Professional Moonphase 3576.50.00 (note the addition of the final ".00" which is sometimes included in reference numbers) is not simply a Speedmaster with a moon phase; it's a carefully considered evolution of the design. It takes the core elements that made the Speedmaster Professional Moonwatch a legend – its robust case, easily legible dial, and reliable chronograph function – and seamlessly integrates the sophisticated complication of a moon phase indicator. This integration is crucial; it doesn't detract from the original design but enhances it, adding a layer of refined elegance without compromising the watch's inherent practicality and ruggedness.
The case, typically measuring 42mm in diameter, is crafted from stainless steel, reflecting Omega's commitment to durable and reliable materials. This size, while larger than some vintage Speedmasters, remains comfortably wearable for most wrists. The brushed finish on the case sides contrasts nicely with the polished bezel and lugs, adding visual texture and depth. The famous tachymeter scale graces the bezel, a hallmark of the Speedmaster line, allowing for speed calculations. The sapphire crystal, resistant to scratches, protects the beautifully detailed dial.
The dial itself is a masterclass in legibility and design. The classic Speedmaster layout is retained, with the three sub-dials for the chronograph function clearly positioned at 3, 6, and 9 o'clock. The moon phase indicator, a circular aperture usually located at 6 o'clock, adds a touch of sophistication without overwhelming the rest of the dial. The hands and indices are typically filled with luminous material, ensuring excellent readability in low-light conditions. The date window, discreetly placed, adds further functionality without disrupting the overall aesthetic balance.
The heart of the 3576.50 is the caliber 1861, a manually wound movement. This movement is a direct descendant of the legendary caliber 861, famously used in the Speedmasters worn on the moon. While not as feature-rich as some of Omega's more modern movements, the 1861 is known for its robustness, reliability, and relative simplicity – qualities highly valued by collectors who appreciate the heritage and mechanical integrity of the watch. The manual winding mechanism adds to the tactile experience of wearing the watch, providing a direct connection to the mechanical heart of the timepiece.
