The Omega Speedmaster Date Ref. 3513.50 is a clean and versatile neo-vintage Speedmaster, offering classic Omega chronograph styling in a compact and wearable case size. This reference features a 39mm stainless-steel case, black dial, tachymeter bezel, sapphire crystal, closed caseback, and stainless-steel bracelet. Powering the watch is Omega’s Calibre 1152 automatic chronograph movement, offering approximately 44 hours of power reserve.

The appeal of the Ref. 3513.50 lies in its balance of practicality and traditional Speedmaster DNA. The black dial features three chronograph registers, luminous hands and applied hour markers, and a date display at 3 o’clock, while the tachymeter bezel reinforces the model’s motorsport-inspired character. Its 39mm proportions make it more compact than the Speedmaster Professional while still giving it a substantial presence on the wrist.

Condition

Please review the photos carefully for an accurate representation. Light scratches, bracelet wear, bezel wear, crystal wear, case wear, or other 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 are light scratches / marks visible in the anti-reflective coating of the sapphire crystal. These are subtle under normal viewing conditions and become noticeably more visible when direct light hits the crystal at certain angles. The crystal itself remains clear, but the coating wear is being disclosed for complete transparency. Please review the photographs carefully for the best representation.

The Ref. 3513.50 is documented with a sapphire crystal and anti-reflective treatment on the inner surface; anti-reflective coatings are separate layers applied to sapphire to reduce reflections.
