Omega Speedmaster Reduced | 39mm Black Dial | Automatic | Ref. 3510.50

The Omega Speedmaster Reduced Ref. 3510.50 is one of the most recognizable neo-vintage Speedmaster models, offering the iconic styling of the Speedmaster collection in a more compact and highly wearable automatic configuration. Housed in a stainless-steel case measuring approximately 39mm, this reference features a black dial, fixed black tachymeter bezel, Plexiglass/Hesalite crystal, and stainless-steel Omega bracelet.

The appeal of the Ref. 3510.50 lies in its balance of classic Speedmaster design and everyday practicality. The black dial features a traditional three-register chronograph layout, luminous hour markers and hands, and contrasting white detailing for excellent legibility. Its smaller proportions make it noticeably more compact than the Speedmaster Professional, while the automatic movement eliminates the need for daily manual winding. The result is a versatile Speedmaster that retains the unmistakable motorsport-inspired character of the collection in an easy-to-wear format.

Condition

Please review the photos carefully for an accurate representation. Light scratches, bracelet wear, bezel wear, crystal wear, case wear, or signs of use consistent with age may be present and do not affect functionality. The watch presents well overall with expected wear for its age.

Please note that there is extremely minor staining/discoloration visible around the center portion of the hands near the hand stack. This is very subtle and can be difficult to notice under normal viewing conditions, but it is being disclosed for complete transparency. Please review the close-up photographs carefully for the best representation.
