About this watch

The Omega Speedmaster Professional Moonwatch 321 Platinum is a stunning tribute to the brand's rich legacy of space exploration. With its platinum case, chronograph movement, and luxurious materials, this watch demands attention without being overly ostentatious. The black onyx dial adds depth, while the stick and dot indexes stand out beautifully. At the core is the Omega caliber 321 B, a hand-wound marvel that pays homage to original Speedmaster movements. With a power reserve of 55 hours and a frequency of 18,000 vibrations per hour, it ensures precision and reliability. The chronograph feature operates through pushers on the side of the watch, engaging the timing mechanism. This timepiece is a celebration of engineering, design, and the spirit of exploration. Its timeless elegance and advanced functionality make it a worthy addition to any watch collection.
