The Omega Speedmaster Professional, a watch synonymous with lunar exploration and enduring style, boasts a rich and varied history. Within that history, certain references and variations command particularly high levels of collector interest. Among these coveted pieces sits the Omega Speedmaster 145.022-69 ST, often referred to as the "69 Tropical," a watch that encapsulates the spirit of a bygone era and the allure of aged patina. This article delves deep into the specifics of this particular reference, exploring its history, features, and the factors that contribute to its exceptional desirability in the collector market.
1969 Omega ST 145.022: A Year of Significance
The year 1969 holds immense significance in the history of the Omega Speedmaster. It marks not only a pivotal year in human history with the Apollo 11 moon landing but also a significant year in the evolution of the Speedmaster itself. The 145.022-69 ST, with its serial number beginning with 2911xxx, firmly places it within this crucial timeframe. This reference represents a transitional phase in Speedmaster production, bridging the gap between earlier models and the later, more refined versions. Understanding this context is vital to appreciating the unique characteristics of the 145.022-69 ST.
The "69" in the reference number doesn't denote a specific modification or feature. Instead, it's a simple reflection of the year of manufacture, adding to the watch's historical significance and collector appeal. The ST designation refers to the stainless steel case material, a standard feature for the Speedmaster Professional.
The Allure of the Tropical Dial:
The most striking feature of the 145.022-69 ST, and the reason for its coveted status, is its "tropical" dial. This isn't a factory-applied effect; rather, it's a result of the natural degradation of the original tritium lume applied to the hands and dial markers. Over time, exposure to ultraviolet light and other environmental factors causes the lume to brown, often developing a rich, warm, and uneven patina. This unique coloration is what gives the "tropical" dial its name and contributes significantly to its aesthetic appeal.
The variation in the browning is what makes each tropical dial unique. No two are exactly alike. Some might exhibit a deep, chocolate-brown hue, while others might show a more subtle, lighter brown. The intensity and distribution of the browning are influenced by several factors, including the watch's exposure to sunlight, the specific chemical composition of the tritium, and even the storage conditions over the decades. This natural aging process is a testament to the watch's history and longevity.
This isn't simply a cosmetic feature; it's a mark of authenticity and a tangible link to the watch's past. The presence of a genuine tropical dial significantly increases the value and desirability of a 145.022, making it a highly sought-after collectible for serious enthusiasts. The process of determining authenticity is crucial, as many attempts to artificially replicate the tropical effect exist. Experienced collectors and watchmakers can identify genuine tropical dials through careful examination of the lume's texture, color consistency, and overall appearance.
