A late-period Cartier Santos Octagon LM in stainless steel with solid 18K yellow-gold bezel and screws, powered by Cartier’s quartz movement. The 30 × 38 mm case, integrated two-tone “Combi” bracelet, and crisp white Roman dial embody the distinctive geometric styling that defines the Octagon within the broader Santos family. A strong, fully sorted early-’90s example with full-set presentation.
Why It’s Special
The Santos Octagon LM represents one of Cartier’s most recognisable transitional designs — blending sport and refinement through its angular bezel and integrated bracelet architecture. This example is presented as a complete full set, including inner and outer boxes, papers, manuals, and hang tags. It has undergone a full professional overhaul in February 2026, including movement service, case disassembly, corrosion treatment, ultrasonic cleaning, light refinishing, and replacement of the crown during service. Balance of a 12-month service warranty remains, materially reducing buyer risk compared with typical market offerings.
Condition
Dial is clean and original with crisp Roman numerals and intact minute track. No visible staining, cracking, or print degradation. Blued hands are correct and clean. Sapphire crystal is clear. Case has undergone professional overhaul and cleaning, with stainless steel brushing remaining defined and polished bevels presenting sharply. Solid 18K bezel and screws show only light superficial wear consistent with careful use, with no deformation or heavy rounding observed. Bracelet is tight with minimal stretch; gold screws are evenly toned and clasp engraving remains crisp. Overall presentation is materially stronger post-service and reflects careful ownership.
Performance: Fully overhauled in February 2026 by a reputable watchmaker. Running correctly and supported by the balance of a 12-month service warranty.
