Omega Speedmaster Triple Calendar - Black Dial

Details

The Speedmaster that does more without trying harder

This Speedmaster Triple Calendar comes from a period when Omega was comfortable expanding the Speedmaster idea without diluting it. Same familiar case shape and overall feel, but with added information layered in a way that still feels balanced. At 39mm, it wears comfortably and stays true to the Speedmaster’s everyday character.

Why this configuration matters

The triple calendar layout is what sets this reference apart. Day, date, and month are integrated cleanly into the dial without crowding it, preserving legibility and symmetry. The black dial keeps everything grounded and readable, letting the complications feel practical rather than ornamental.

This reference sits in an interesting middle ground. More involved than a standard Speedmaster, but far less busy than full calendar chronographs from the same era. It is a thoughtful execution rather than a maximal one. Automatic movement fits the intent perfectly. This was designed to be worn regularly, not wound ceremonially.

What you need to know before wearing it

Condition is very good throughout. The case, bezel, and bracelet are all in very good shape. The dial and crystal are clean and well preserved. The movement is running well and all functions operate as intended. 

Why this watch still works

This is a Speedmaster for someone who wants a little more information on the dial without giving up the familiar look and feel. Practical, balanced, and easy to live with.

It works as a daily chronograph, a more interesting alternative to the standard Speedmaster, or a quiet sleeper from Omega’s 1990s catalog. Familiar enough to recognize, different enough to keep your attention.

Every watch we offer has been authenticated and mechanically looked over to ensure immediate usability.

Bracelet extension, cutting, or sizing is available upon request through our professional in-house jewelers.

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.
