The Omega Speedmaster Professional "Moon to Mars" Edition, model number 3577.50.00, is a unique and symbolic watch that continues Omega's famous connection to space travel. This special edition celebrates not only the historic moon missions, but also the future plans for manned missions to Mars. Design and aesthetics: Dial: The most striking feature of this watch is its dial, which is characterized by differently colored subdials for the chronograph functions, meant to represent the surfaces of the Moon, Earth and Mars. This design element is not only visually appealing, but also reflects Omega's commitment to space travel. The main colors of the dial are black, with the subdials designed in gray, blue and red. Case: The 42mm case is made of stainless steel and perfectly matches the robust and functional character of the Speedmaster series. As with traditional Speedmaster watches, the bezel is equipped with a tachymeter scale, useful for measuring time during scientific and sporting activities. Technical features: Movement: The "Moon to Mars" is powered by the Omega Caliber 1861, a hand-wound chronograph movement that has a direct lineage from the original Moonwatch Caliber 861. This movement is known for its reliability and was chosen for the Apollo missions due to its robustness and accuracy. Water resistance: The watch is water resistant up to 50 meters, which protects it against splashes and short immersions, but makes it unsuitable for diving. Bracelet: The bracelet is typically a black leather strap with a stainless steel clasp, which complements the classic and timeless look of the Speedmaster Professional. It is also possible to choose a stainless steel bracelet for an even more robust look. The Omega Speedmaster Professional "Moon to Mars" 3577.50.00 is more than just a watch; it is a piece of space history and a testament to Omega's role in this exciting chapter of human discovery. It is ideal for collectors and enthusiasts seeking a watch with deep historical significance and a strong narrative component. We offer you a 1-year warranty.
