Omega Speedmaster ref 3592.50 from 1993 APOLLO XI

A beautiful example of the beloved Speedmaster Professional 3592.50, the transitional “sapphire sandwich before the sandwich” that collectors chase. This 1993 piece blends warm tritium charm with the visual poetry of the copper-toned calibre 863—Omega’s decorated display-back version of the 861, the movement lineage worn during the Apollo program.

On the sapphire caseback you get the iconic “Apollo XI” engraving, a tribute to the mission that defined the Speedmaster’s place in history. Freshly serviced, running perfectly, and complete with its original bracelet, this is a ready-to-wear collectible with genuine lunar heritage.

Technical Background

Reference 3592.50 sits in the transitional era: a hesalite crystal up front—true to the Apollo-era specification—and a sapphire display back revealing the gilt-finished 863. The caseback ring carries the Apollo XI text, marking this as one of the commemorative display-back Speedmasters from the early ’90s. Tritium indices give the dial that soft vintage tone only time can create.
