The Omega Speedmaster Professional, affectionately known as the "Moonwatch," holds a unique place in horological history. Its association with NASA's Apollo missions and its enduring design have cemented its status as an iconic timepiece. While the caliber 1861 and, more recently, the 3861, often dominate conversations surrounding the Speedmaster Professional, the caliber 1863 deserves its own spotlight. Though less frequently discussed, the 1863 movement powered a significant number of Speedmaster models, representing a crucial chapter in the watch's evolution. This article will delve into the details of the Omega Speedmaster equipped with the caliber 1863, examining its features, comparing it to other Speedmaster movements (like the 1861 and 3861), and exploring its place within the broader context of Omega's legendary chronograph.
The Omega Speedmaster Professional: A Timeless Design
Before focusing specifically on the 1863, it's crucial to understand the fundamental characteristics of the Speedmaster Professional. This iconic watch boasts a distinct design language, immediately recognizable to watch enthusiasts and casual observers alike. The classic Speedmaster features a black dial, often referred to as a "panda" dial in certain variations due to its contrasting sub-dials. This black dial, protected by a scratch-resistant sapphire crystal (in more modern iterations; earlier models used Hesalite), provides a stark backdrop for the highly legible hour markers and hands. The three sub-dials – a small seconds sub-dial, a 30-minute recorder, and a 12-hour recorder – are meticulously arranged, providing a balanced and functional aesthetic. The central chronograph seconds hand adds to the overall functionality.
This layout, refined over decades, is a testament to Omega's commitment to both style and practicality. The design is simultaneously robust and elegant, capable of withstanding the rigors of space travel while remaining a sophisticated and desirable wristwatch. The prominent tachymeter scale on the bezel further enhances the watch's functionality, allowing for speed calculations.
Omega Speedmaster 311.30.42.30.01.005 on Sale: A Modern Interpretation
While this article focuses primarily on the historical significance of the caliber 1863, it's worth acknowledging the modern iterations of the Speedmaster Professional. The reference number 311.30.42.30.01.005, often found on sale through authorized retailers and reputable grey market dealers, represents a contemporary example of the Speedmaster legacy. This model typically features the more modern caliber 3861, offering improved performance and chronometric accuracy compared to its predecessors. However, examining models like the 311.30.42.30.01.005 provides a valuable contrast to understanding the evolution of the Speedmaster and the place of the older 1863 movement.
