This article delves deep into the specifics of the 311.33.42.30.01.001, exploring its design, movement, history, and what makes it a coveted piece for collectors and enthusiasts alike.
The Essence of the Omega Speedmaster 311.33.42.30.01.001
The reference number itself, 311.33.42.30.01.001, is a key identifier for this specific configuration. Each digit within this code signifies specific attributes of the watch, from the case size and material to the dial color and movement. Understanding this numbering system allows for precise identification within the vast Omega Speedmaster family.
This particular Speedmaster boasts a classic, instantly recognizable design. The 42mm stainless steel case houses a black dial, protected by a prominent, domed Hesalite crystal. This choice of crystal, while seemingly simple, is crucial. Hesalite, unlike sapphire crystal, is more resistant to shattering upon impact, a vital characteristic for its historical use in extreme conditions. The slightly softer nature of Hesalite also contributes to the unique, slightly magnified view of the dial, a characteristic appreciated by many Speedmaster enthusiasts. The slightly aged, almost vintage-looking effect that comes with the Hesalite crystal's ability to develop a patina over time is a sought-after feature.
The black dial is meticulously crafted, showcasing the iconic Speedmaster layout. Three subsidiary dials are prominently featured: a small seconds sub-dial at 9 o'clock, a 30-minute recorder at 3 o'clock, and a 12-hour recorder at 6 o'clock. These sub-dials, combined with the central chronograph seconds hand, allow for precise timing of events up to 12 hours. The applied indices and hands, often filled with luminous material for optimal legibility in low-light conditions, provide a crisp contrast against the dark dial. The Omega logo is subtly yet proudly placed at 12 o'clock, while the "Speedmaster Professional" inscription is found below, confirming its heritage.
