The Omega Speedmaster Professional is a legend, a watch synonymous with space exploration and enduring style. Within the vast Speedmaster family, the reference 3521.80 holds a special place, representing a specific era of production and a particular aesthetic that continues to captivate collectors and enthusiasts alike. This article delves into the details of the Omega Speedmaster 3521.80, exploring its features, history, and current market value, while also touching upon related models and their appeal.
The 3521.80 is a manual-winding Speedmaster Professional, a direct descendant of the iconic Moonwatch worn on the lunar surface. Unlike some later models featuring automatic movements, this reference adheres to the classic, reliable, and robust manual caliber 1861, a direct evolution of the legendary caliber 861. This movement, known for its simplicity and durability, is a key factor in the watch's enduring appeal. Its reliable performance and relative ease of servicing contribute to the 3521.80’s reputation as a robust and dependable timepiece.
Distinguishing Features of the 3521.80:
The 3521.80 boasts the quintessential Speedmaster design elements:
* The Iconic Case: The 42mm stainless steel case is the hallmark of the Speedmaster Professional. Its sturdy construction and brushed finish give it a classic, understated elegance. The slightly larger size compared to some vintage models makes it comfortable for a wider range of wrists.
* The Hesalite Crystal: Unlike some later models that incorporated sapphire crystals, the 3521.80 retains the original Hesalite crystal. While less scratch-resistant than sapphire, Hesalite has a unique characteristic: it shatters in a way that prevents sharp shards from flying off, making it safer in extreme conditions. Moreover, many enthusiasts appreciate the slightly warmer, more vintage aesthetic of the Hesalite crystal.
* The Legendary Dial: The black dial features the distinctive Speedmaster subdials, arranged in the classic tri-compax layout: a 30-minute chronograph counter at 3 o'clock, a 12-hour chronograph counter at 6 o'clock, and a small seconds subdial at 9 o'clock. The applied indices and luminous hands provide excellent legibility, even in low-light conditions. The "dot over ninety" on the seconds subdial is a further testament to its lineage, a detail that distinguishes true Speedmaster Professionals.
* The Caliber 1861 Movement: As mentioned earlier, the manual-winding caliber 1861 is the heart of the 3521.80. This robust movement is highly regarded for its reliability and ease of maintenance. Its visible movement through the exhibition caseback (on some versions) provides a fascinating glimpse into the intricate mechanics.
Finding the Right 3521.80:
