The Omega Speedmaster Reduced Ref. 175.0033 (often nicknamed "Golden Eyes" for its white dial and contrasting gold subdials) is a vintage two-tone automatic chronograph produced from the late 1980s through the 1990s. It offers the classic Speedmaster aesthetic in a more compact, wrist-friendly 39mm case.

• Case & Dimensions. The stainless steel case measures 39mm in diameter, with a compact lug-to-lug length of approximately 44.5mm to 45mm and a thickness around 12mm to 12.5mm. 

• Two-Tone Accents. It features a solid 18k yellow gold tachymeter bezel, along with gold-toned crown and chronograph pushers. 

• Dial & Crystal. The matte white dial houses three recessed, concentric-patterned gold subdials ("golden eyes") for the running seconds, 30-minute counter, and 12-hour counter, protected by a domed hesalite (acrylic) crystal. 

• Movement. Powered by the Omega Caliber 1140 (or the later Caliber 1143), which pairs an ETA 2890-2 / 2892-A2 automatic base with a Dubois-Dépraz 2020 chronograph module. It features 45–46 jewels, beats at 28,800 vph, and offers an approximate 38-to-42-hour power reserve. 

• Water Resistance. Rated to 5 bar (50 meters / 167 feet) with a snap-on (press-in) case back. 

• Strap / Bracelet. Originally sold on either a two-tone steel and 18k gold bracelet (Ref. 1469/811) or a leather strap with an Omega pin buckle.
