Omega Speedmaster Reduced | 39mm Black Dial | Ref 3510.50 I

The Omega Speedmaster Reduced Ref. 3510.50 is one of the most approachable ways to experience the iconic Speedmaster design, offering the same classic look in a more compact ~39mm case. Originally introduced as a smaller, more wearable alternative to the Moonwatch, it keeps the signature tachymeter bezel and tri-compax chronograph layout while delivering a size that fits comfortably on almost any wrist.

Powered by an automatic chronograph movement, the Reduced is built for easy daily wear—no winding, no hassle—just consistent performance. It maintains the core Speedmaster DNA while adding practicality, making it a great choice for someone who wants the heritage of the Speedmaster line in a more versatile and wearable format.

What makes the 3510.50 special is how well-rounded it is. It’s not trying to be oversized or overly technical—it’s simply a clean, balanced chronograph that works in any setting. Whether it’s your first Speedmaster or an everyday piece in a larger collection, this is the kind of watch that just fits naturally into rotation.
