About this watch
The Omega Speedmaster Professional Moonwatch Big Box / Sapphire is a masterpiece of luxury watchmaking, blending timeless design with cutting-edge technology and rich historical significance. This iconic timepiece boasts a black dial with stick and dot indexes, set within a robust yet refined 42 mm round stainless steel case. The sapphire crystal adds an extra layer of protection while providing crystal-clear visibility. One of the standout features is its tachymeter bezel, allowing you to measure speed based on time traveled over a fixed distance. This watch combines form and function, with precision-designed stick hands, a small seconds hand for added sophistication, and luminous indexes that shine bright in low-light conditions. The Omega Caliber 1863 movement represents the luxury version of its predecessor, the 1861, showcasing Omega's dedication to precision and craftsmanship. With a power reserve of 48 hours and a frequency of 21,600 vibrations per hour, you can trust that this watch will keep ticking accurately. The chronograph feature is a must-have for any serious timepiece, perfect for timing events or tracking laps. The pushers on the side are tactile and satisfying, giving users a sense of control and precision. With a water resistance rating of 50 meters and durable stainless steel construction, this watch can handle splashes and brief submersion, making it suitable for everyday wear. Whether you're a seasoned collector or a first-time buyer, the Omega Speedmaster Professional Moonwatch Big Box / Sapphire is a tribute to human achievement and a testament to Omega's craftsmanship.
