Omega Speedmaster Reduced | 39mm Black Dial with Yellow Patina | Ref 3510.50 I

The Omega Speedmaster Reduced Ref. 3510.50 is one of the most wearable takes on the iconic Speedmaster, offering the same classic look in a more compact ~39mm case . This example features a black dial that has developed a warm yellow patina, giving it a unique vintage character that sets it apart from standard models. The contrast between the aged lume and deep black dial adds depth and personality, making it feel far more special on the wrist.

Powered by an automatic chronograph movement, the Reduced delivers reliable everyday performance while maintaining the classic Speedmaster DNA—tachymeter bezel, tri-compax layout, and strong legibility. Originally introduced as a more accessible and wearable alternative to the Moonwatch , it’s become a favorite for collectors who want heritage, comfort, and individuality all in one piece.
