Omega Speedmaster Reduced 3511.20 – Steel Matte White Dial

Details

A Familiar Case With A Cleaner Contrast

This Speedmaster Reduced keeps the classic Speedmaster case and proportions, but the matte white dial shifts the tone entirely. Same silhouette, same layout, but the color choice changes how it feels on the wrist. It is still unmistakably a Speedmaster, just brighter and more direct.

Why This Configuration Matters

The matte white dial is the defining element here. It gives the chronograph layout clarity and separation without relying on heavy contrast. The sub dials remain distinct, and the overall presentation feels crisp and purposeful. The register layout stays balanced and easy to follow, and the date integrates cleanly without interrupting the design. The lume on the hands and hour markers has aged evenly, adding subtle warmth that keeps the white dial from feeling flat.

What You Need To Know Before Wearing It

This watch is in very good condition. It remains completely original, including the signed Omega crown, caseback, dial, and movement. The case retains its factory finishing with only light wear consistent with age. The dial is clean and well preserved, and the sapphire crystal remains clear. The automatic chronograph movement is running properly and delivers the daily usability expected from the Reduced while keeping the Speedmaster character intact. This example comes with it's original papers and warranty card entailing it's serial number and reference. 

Why This Watch Still Works

The Speedmaster Reduced has built its reputation on wearability. It works as a daily chronograph, a lighter counterpart to a traditional Moonwatch, or a standalone Speedmaster for someone who prefers clarity over drama.

History

In 1957, Omega released the Speedmaster as a racing chronograph. Eight years later, NASA put it through a battery of extreme tests — temperature, humidity, vacuum, shock, vibration, acceleration — and in 1965 certified it as the official watch for all manned space missions.

On July 20, 1969, Buzz Aldrin wore his Speedmaster on the surface of the Moon. No other watch has been to the Moon. That fact has never stopped mattering to anyone who cares about watches.

The Speedmaster's production history across our inventory is rich: the manual-wind Professional (ref 145.022 from 1969 itself), the Reduced automatic (3510.5, 3511.5, 3511.8 with date), the Triple Calendar series (3521, 3523.3), the Michael Schumacher limited editions (3810.12, 3518.5), and the AC Milan and Schumacher World Champion 2000 editions. Each variant was built on the same essential chassis — the 39mm steel case, the tachymeter bezel — and each one lands somewhere on the continuum between racing instrument and artifact of human achievement.
