The Omega Speedmaster. A name synonymous with lunar exploration, precision timing, and enduring style. While no single Speedmaster model has been universally "discontinued" in the sense that it's completely vanished from Omega's offerings, the story of the Speedmaster is one of constant evolution, with specific references and movements phased out over time, replaced by newer iterations. This evolution, however, doesn’t diminish the legacy of these discontinued models, particularly those like the reference 145.012, inextricably linked to momentous achievements like the first confirmed snowmobile expedition to the North Pole.
In 1968, a year pivotal in Speedmaster history, Ralph Plaisted and his team etched their names into the annals of exploration. Their successful journey to the North Pole, achieved using snowmobiles and navigational tools including sextants and the trusty Omega Speedmaster reference 145.012, stands as a testament to the watch's reliability and resilience. This particular Speedmaster, already proven in the crucible of the Apollo missions, demonstrated its versatility beyond the vacuum of space, thriving in the harsh, unforgiving conditions of the Arctic. This reinforces the Speedmaster's reputation not just as a space explorer's tool, but as a robust and dependable timepiece for any challenging environment. The 145.012, with its iconic design and the legendary caliber 321 movement, represents a pinnacle of Speedmaster history, and its use in this groundbreaking expedition further solidifies its legendary status. While no longer in production, examples of the 145.012 remain highly sought after by collectors, commanding significant prices in the pre-owned market.
This same year, 1968, also marked a significant internal change within Omega's Speedmaster lineage. Omega transitioned from the caliber 321 movement, a manually wound marvel that powered many of the early Speedmasters, including the 145.012 used by Plaisted and his team, to the new caliber 861. This shift, while representing technological advancement, also marked the end of an era for the 321, a movement now considered highly collectible and a symbol of the Speedmaster's early glory days. The caliber 861, while a different beast, continued the Speedmaster's legacy of robust performance and accuracy, paving the way for future iterations of the iconic chronograph. This transition highlights the ongoing evolution of the Speedmaster, a constant refinement and improvement that has kept the watch relevant and desirable for decades.
