Introducing the legendary Omega Speedmaster 3520.50.00 — a watch that combines the iconic Speedmaster DNA with one of the most feature-packed dials Omega has ever produced.
Crafted in stainless steel with a versatile 39mm case, the Speedmaster Triple Date delivers the perfect balance between sportiness and everyday wearability. Beneath the sapphire crystal lies a striking black dial displaying a chronograph, day, date, month, 24-hour indicator and small seconds, making it one of the most practical Speedmasters ever created.
Powering this masterpiece is the automatic Omega Calibre 1151, renowned for its reliability and smooth operation. With a power reserve of approximately 42 to 44 hours and a robust chronograph architecture, it was designed for those who appreciate both mechanical sophistication and everyday functionality.
Collectors often refer to this reference as the “Mk40” due to its distinctive dial layout and abundance of complications. Despite its impressive specification sheet, it remains one of the best-value Speedmasters on the market today, offering far more functionality than many watches at a similar price point. Enthusiasts frequently describe it as one of the most underrated Speedmasters ever produced.
Whether you’re a seasoned collector or searching for your first serious Omega, the Speedmaster 3520.50.00 stands out as a unique piece that combines heritage, practicality and mechanical excellence. It’s a watch that rewards a closer look every time it finds its way onto your wrist.
