Omega speedmaster 'moonwatch' from 1993 With warranty card

Omega Speedmaster Professional “Moonwatch”

Ref. 3590.50 – Sold in 1993

An icon needs little introduction. This Omega Speedmaster Professional ref. 3590.50 represents the pure, tritium-era Moonwatch in its most honest and wearable form. With its warm patinated lume, classic stepped dial and legendary hand-wound movement, this is the Speedmaster exactly as collectors want it today.

This example was sold in 1993, comes with its original Omega warranty card, and has been freshly serviced, making it a rare opportunity to acquire a correct, ready-to-wear Moonwatch with strong provenance. A timeless chronograph that connects directly to Omega’s space-flight heritage, yet remains perfectly usable as a daily watch.

Technical background

The reference 3590.50 is powered by the calibre 861, the direct descendant of the movement qualified by NASA for all manned space missions. By the early 1990s, this reference marked the end of the tritium era, making these watches especially appealing for their warm vintage character combined with modern reliability.
