The Omega Speedmaster Professional, affectionately known as the Moonwatch, is an icon. Its history is intertwined with space exploration, its design a testament to enduring style, and its functionality a benchmark for precision timekeeping. But for many prospective buyers, one crucial specification often tops the list of considerations: thickness. At a price point often exceeding $9,500.00, understanding the dimensions of the 2021 models and their predecessors is paramount. This article will delve into the thickness of the 2021 Omega Speedmaster Professional, comparing it to previous iterations and exploring related aspects of this legendary timepiece, including its water resistance, dial variations, case dimensions, and the iconic tachymeter bezel.
Omega Speedmaster 2021 Thickness: Context is Key
Before focusing specifically on the 2021 models, it's crucial to establish a historical perspective. The Speedmaster's design has evolved subtly over the decades, resulting in variations in thickness. The early Speedmasters, particularly those from the 1950s and 60s, were generally thinner than their modern counterparts. This is largely attributed to advancements in movement technology and the incorporation of features aimed at enhancing durability and functionality. The legendary Calibre 321, for instance, while incredibly accurate, occupied a smaller space than its successors. The introduction of the Calibre 861 and later the Calibre 1861, while robust and reliable, contributed to a slight increase in case thickness.
The 2021 Speedmaster Professional models, generally referencing the reference number 311.30.42.30.01.005 and its variations, maintain a relatively consistent thickness, though precise measurements can vary slightly depending on the specific model and its features. While Omega doesn't explicitly advertise a single thickness for all 2021 models, a general range of approximately 13.2mm to 13.8mm is often cited. This variation can be attributed to factors such as the type of crystal (sapphire versus Hesalite), the presence of any applied decorations or coatings, and minor manufacturing tolerances.
Comparing this to previous generations, we see a noticeable difference. The vintage Speedmasters, particularly those worn on the moon, boasted a slimmer profile, often measuring around 12mm or less. This difference, though seemingly minor, contributes significantly to the overall feel and wearability of the watch. The increased thickness in modern models is largely a result of the improved movement, the sapphire crystal (often preferred for its scratch resistance over the original Hesalite), and the more robust construction aimed at meeting modern standards of durability and water resistance.
Is Omega Speedmaster Waterproof?
The water resistance of the Omega Speedmaster Professional is a frequently asked question. While not designed as a dedicated dive watch, the Speedmaster Professional offers a respectable level of water resistance. Modern models generally boast a water resistance rating of 50 meters (165 feet). This is sufficient for everyday wear and accidental splashes, but it is not suitable for swimming or diving. It's crucial to remember that this rating is under controlled conditions and can be affected by factors such as age, wear and tear, and the condition of the gaskets. Regular servicing is essential to maintain the water resistance of any watch, especially one with a history as rich as the Speedmaster.
