Omega Speedmaster Date | Black Reverse Panda Dial | Yellow Patina I Ref. 3511.50

The Omega Speedmaster Date Ref. 3511.50 is a distinctive neo-vintage Speedmaster featuring a highly wearable 39mm stainless steel case, black reverse-panda dial, stainless steel tachymeter bezel, sapphire crystal, and matching steel bracelet. Its contrasting silver-toned subdials give the watch a sportier and more visually dynamic appearance than a traditional all-black Speedmaster configuration.

This particular example is distinguished by the warm yellow patina visible across the luminous hour markers. The aged coloration creates an attractive contrast against the black dial and gives the watch additional vintage character. The date wheel also displays small visible staining, which has been disclosed for complete transparency.

The three-register layout includes running seconds, a 30-minute counter, and a 12-hour counter, along with a date window at 3 o’clock. The watch is powered by an Omega self-winding movement based on the reliable Valjoux 7750 architecture, offering practical everyday use alongside the classic Speedmaster design.

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. The luminous hour markers display noticeable yellow patina. The date wheel also shows tiny visible staining and discoloration. These cosmetic characteristics are clearly disclosed and should be reviewed closely in the photographs.
