The history of this Omega Speedmaster
The House of Omega presents an absolute icon of space exploration. Initially conceived in 1957 for racing drivers, the chronograph established itself with NASA to become the reference outside the atmosphere. Reference 3590.50.00 illustrates a fascinating transition period for collectors. The historical anecdote of this lineage lies in the adoption of the cam-type caliber in 1968, incorporating a polymer brake called Delrin, specifically designed to absorb shocks and reduce wear on the central wheel without the need for lubrication. This technical evolution underlines the purely utilitarian and rigorous vocation of the instrument.
Case, caliber and bracelet of this Speedmaster
The asymmetrical 42mm stainless steel case features lyre lugs and a subtle alternation of polished bevels and brushed sides. The domed Hesalite crystal protects an exceptional dial whose lacquer has naturally evolved into a chocolate hue. This patina, coupled with the eggshell-colored indexes and tritium hands, lends a unique aesthetic. The display is organized around a small seconds and chronograph counters totaling 30 minutes and 12 hours, framed by the famous black aluminum tachometric bezel. A previous owner chose to equip this timepiece with a transparent sapphire caseback revealing the mechanics. It is powered by the hand-wound Calibre 861, vibrating at 21,600 vibrations per hour and offering a 48-hour power reserve. The whole is mounted on the sought-after folded-link steel bracelet identified by the nomenclature 1171 and its end pieces 633, closed by a single folding clasp.
Why this Omega watch
The major interest of this configuration lies in the metamorphosis of its dial. Obtaining a homogeneous brown patina known as tropical is a rare natural phenomenon linked to the aging of protective varnishes. The true watchmaking value of this model lies in the formal validation of this hue by the Manufacture's archives, an exceptional fact that reassures and enthuses purists. It's an opportunity to acquire a piece of history with a singular visual identity, particularly prized on the vintage chronograph market where authenticity dictates exclusivity.
