The gold-plated (SGP) case retains its classic vintage geometry, featuring a polished stepped bezel, clean lug bevels, and slim side profiles that allow the watch to sit comfortably and discreetly on the wrist. Every component of the watch head is completely original to the piece, including the factory dial, 5740C high-beat movement, hands, acrylic crystal, case, and crown, and it has been fitted with a high-quality black leather strap that complements its warm gold tones.
