Omega Speedmaster Reduced | 39mm Black Dial | Sapphire Crystal | Ref. 3539.50

The Omega Speedmaster Ref. 3539.50 is a later-generation Speedmaster Reduced that captures the recognizable styling of the classic Speedmaster in a more compact 39mm case. It features a black chronograph dial, black tachymeter bezel, scratch-resistant sapphire crystal, and stainless steel bracelet.

Powered by the self-winding Omega Calibre 3220, the watch offers chronograph functionality, small seconds, and an approximately 40-hour power reserve. Its automatic movement and midsize proportions make it a practical alternative for those who enjoy the Speedmaster design but prefer a smaller and more convenient everyday watch.

The sapphire crystal and original 100-meter water-resistance rating distinguish the 3539.50 from many earlier Speedmaster Reduced configurations. Its discontinued status, traditional black-dial design, and highly wearable proportions make it an appealing neo-vintage Speedmaster.

Condition

Please review the photographs carefully for an accurate representation. Light scratches, bracelet wear, bezel wear, crystal wear, or other signs of use consistent with age may be present and do not affect functionality.
