The Omega Speedmaster Professional is a watch steeped in history, a legend forged in the fires of space exploration. While the instantly recognizable Speedmaster Professional "Moonwatch" is often associated with the manually-wound Calibre 321, the reference 3221.30 represents a significant chapter in the Speedmaster's evolution, showcasing a different, yet equally compelling, side of this iconic timepiece. This article delves into the specifics of the Omega Speedmaster 3221.30, exploring its features, its place within the Speedmaster lineage, and its enduring appeal to collectors and enthusiasts alike. We will also touch upon related models and their market value, addressing searches such as "Omega Speedmaster 321 for sale," "Omega Speedmaster 321 price," and "Speedmaster 321 for sale," while clarifying the distinctions between the 321 and 3221.30 movements.
The Omega Speedmaster 3221.30 is powered by the Omega calibre 3606, a self-winding chronograph movement. This is a key differentiator from its predecessors, many of which, notably those associated with the Apollo missions, utilized the manually wound Calibre 321. The 3606 offers a significant advantage in terms of convenience, eliminating the need for manual winding. Its automatic winding mechanism uses the natural motion of the wearer's wrist to maintain the power reserve, a feature that greatly enhances the practicality of the watch for everyday use. This self-winding mechanism, coupled with its 25 jewels, contributes to the movement's reliability and accuracy. The 44-hour power reserve provides ample timekeeping capabilities, ensuring the watch remains operational even if it’s not worn for an extended period. This contrasts with the shorter power reserve often found in manually wound movements like the Calibre 321, necessitating more frequent winding.
