The Omega Speedmaster Professional Chronograph has a legacy etched in history, synonymous with lunar exploration and enduring style. While the Moonwatch remains the iconic representative of the Speedmaster line, other models offer a compelling blend of heritage and contemporary design. The Omega Speedmaster Chronograph Automatic, reference 3510.50.00 (often simply referred to as the 3510.50), occupies a unique space within this rich lineage. This article delves deep into this specific model, exploring its features, history, variations, and what makes it a desirable choice for watch enthusiasts. We'll also touch upon related models like the Omega Speedmaster 3510.00 and consider the broader context of the Speedmaster family.
The Omega Speedmaster 3510.50.00: A Detailed Examination
The 3510.50.00 is a compelling example of Omega's ability to meld classic Speedmaster design elements with a more refined, everyday-wearable aesthetic. Unlike the rugged, tool-watch aesthetic of the Professional Moonwatch, the 3510.50 presents a slightly more polished and versatile look. This is achieved through subtle yet significant design choices.
The case, typically measuring 39mm in diameter (a popular size for many enthusiasts), is crafted from stainless steel, often described as 316L stainless steel, known for its corrosion resistance and durability. This size strikes a balance between comfortable wearability and the presence of a classic chronograph. The caseback is typically solid, concealing the automatic movement within. The lugs are elegantly curved, contributing to the watch's overall refined appearance.
The dial is where the 3510.50 truly shines. While variations exist, many feature a classic tri-compax layout, with three sub-dials arranged neatly at 3, 6, and 9 o'clock. These sub-dials indicate the chronograph's running seconds, 30-minute counter, and 12-hour counter respectively. The hour markers are often applied indices, offering excellent legibility, complemented by luminous material for low-light visibility. The hands are similarly styled, ensuring a cohesive and balanced dial design. The date window, subtly integrated at 6 o'clock, adds a practical touch without disrupting the overall aesthetic balance.
Powering the 3510.50 is an automatic movement, typically an Omega calibre 1151 or a variation thereof. This movement is based on the robust ETA 7750, a well-respected chronograph movement known for its reliability. Omega's in-house modifications and finishing elevate the movement beyond a standard ETA base, adding a touch of luxury and precision. The power reserve is typically around 44 hours, providing ample timekeeping capability.
