A late-1980s Cartier Santos de Cartier Octagon (LM) in two-tone steel and solid 18K gold, powered by Cartier’s dependable Quartz Calibre 90. The signature screw-set bezel, sapphire crystal, and octagonal case deliver the unmistakable Santos design in a 30×38 mm format that wears elegantly and comfortably on the wrist.
Why It’s Special
The Santos Octagon represents Cartier’s late-1980s design language — blending precision quartz technology with enduring elegance. Its brushed steel case and solid-gold accents balance utility and luxury, while the champagne dial has developed a rich, even patina that enhances its warmth and depth. Period-correct and distinct, it remains a refined expression of Cartier’s timeless Santos aesthetic.
Condition
Excellent vintage condition overall. The champagne dial shows a consistent, attractive patina with crisp Roman numerals and blued sword hands. The stainless-steel case and bracelet retain sharp lines, while the solid 18K gold bezel has been lightly polished in recent years to refresh its appearance. Minor hairlines and natural wear are visible under close inspection, consistent with careful use. Bracelet shows light stretch but maintains a firm, secure fit (≈ 17.1cm wrist). The included Cartier presentation box shows light interior ageing consistent with long-term storage.
Performance: Quartz movement running correctly with a fresh battery installed August 2025.
