The Omega Seamaster 166.003 in solid 18k gold is a quintessential vintage dress watch from the 1960s, highly valued for its elegant 34mm proportions and robust automatic movement.  This specific configuration, featuring a champagne dial, represents one of the more luxurious executions of the reference.

• Case Material: Solid 18k Yellow Gold (750).

• Case Diameter: 34mm (often listed up to 34.5mm), with a slim profile of approximately 10mm–12mm in thickness.

• Μηχανισμός: Typically powered by the 24-jewel Caliber 562 or Caliber 565 automatic movements. The Caliber 565 is particularly desirable as it includes a quickset date function activated by pulling the crown to the outermost position.

• Καντράν: Sunburst champagne finish with applied gilt baton hour markers and a date aperture at the 3 o'clock position.

• Crystal: Domed acrylic (Plexiglass), which can often be polished to remove light scratches.
