About this watch

The Omega Speedmaster Professional Missions Gemini VI is a masterpiece of luxury watchmaking. This limited edition timepiece celebrates the Gemini VI space mission with its striking black dial and stainless steel case measuring 42mm in diameter. The plexi glass adds a vintage charm, while the tachymeter bezel offers a sporty touch. At the heart of this watch lies the Omega caliber 1861, a hand-wound chronograph movement renowned for its reliability and precision. With a power reserve of 48 hours and a frequency of 21,600 vibrations per hour, it keeps time admirably. The small seconds, hours, and minutes hands offer a traditional analog display that harkens back to the original Speedmaster models. The Omega Speedmaster Professional Missions Gemini VI is not just a watch; it's a piece of history, a testament to Omega's dedication to quality and innovation.
