Description from the seller
Omega Speedmaster Automatic
An exceptional and highly collectible Omega Speedmaster Day-Date (often referred to by collectors as the "Cosmos" or "Mark 40" edition). This timepiece elegantly merges the iconic Speedmaster racing DNA with a sophisticated triple-calendar complication. Driven by the robust and reliable automatic Omega Calibre 1151, this model stands out with its multi-functional matte black dial, contrasting red chronograph hands, and a distinct AM/PM 24-hour sub-dial split in blue and black.
The case back proudly features the legendary Speedmaster Sea-Monster medallion alongside its serial number 56959535.
