The Omega Speedmaster Professional 145.012. The mere mention of this reference number conjures images of lunar landings, pioneering space exploration, and a legacy of unparalleled horological achievement. But beyond the romanticism and the historical significance lies a watch that commands respect for its technical prowess and its status as the final iteration of a legendary lineage: the last Speedmaster to house the coveted caliber 321 movement. This article delves deep into the fascinating world of the 145.012, exploring its history, its technical specifications, its place in the Omega Speedmaster pantheon, and its current market position within the context of Omega Speedmaster professional price discussions.
A Legacy Forged in the Crucible of Space:
The Omega Speedmaster’s journey to becoming the “Moonwatch” is a story well-documented, a tale of rigorous testing and unwavering reliability in the face of extreme conditions. The 105.003, 105.012, and 145.012 models all played crucial roles in this narrative, each representing a stage in the evolution of this iconic timepiece. However, the 145.012 holds a unique position; it’s the final chapter in the story of the Speedmaster powered by the legendary caliber 321 movement. This movement, based on the Lémania 27CH C12, is considered by many to be the pinnacle of mechanical watchmaking artistry, a masterpiece of precision and elegance. Its column-wheel chronograph mechanism, renowned for its smooth operation and tactile feedback, represents a bygone era of horological craftsmanship. The transition to the caliber 861, while improving certain aspects of production and maintenance, marked a departure from the hand-finished intricacies of the 321.
The 145.012: A Detailed Examination:
The Omega Speedmaster Professional 145.012 is more than just a watch; it's a piece of history. Its design, while seemingly simple, reflects a deep understanding of functionality and durability. The iconic 42mm stainless steel case, with its symmetrical lugs and broad arrow hands, is instantly recognizable. The black tachymetric bezel, a crucial element for timing speed, is a testament to the watch's racing heritage, while the applied indices and luminous hands ensure excellent readability, even in low-light conditions. The hesalite crystal, chosen for its robustness and resistance to shattering, further underscores the watch's suitability for demanding environments.
The dial, often referred to as a "step dial" due to its subtle recessed sub-registers, is another key characteristic of the 145.012. The subtle variations in dial printing and the placement of the logo and text across different production runs contribute to the fascinating diversity within this reference number. These subtle differences have become significant points of discussion amongst collectors, further enhancing the watch's allure. The movement, the caliber 321, is a marvel of engineering, a testament to the horological expertise of the era. Its intricate construction, visible through the exhibition caseback (on some variations), is a feast for the eyes, offering a glimpse into the heart of this legendary timepiece.
