1995 Omega Speedmaster Day-Date ref. ST 375.0084 (MK40)

This is the Omega Speedmaster Day Date reference ST 375.0084, often referred to as the MK40. Produced in the 1990s, this model has developed a strong following for its distinctive, colorful dial layout and full calendar functionality, housed in the familiar Speedmaster case.

The matte grey dial features a well-balanced mix of color and function. Blue, yellow, and red accents add visual interest without feeling overdone. The 24-hour subdial at nine o'clock stands out with its half-blue design, and the outer date track integrates cleanly into the layout. Aged lume on the hands and indices gives the watch a slightly vintage feel.

The watch is running well, with all functions operating properly. It’s offered on a strap as shown, with no box or papers. A great example of a lesser-seen Speedmaster reference that offers both complication and personality.
