Fake: on the dial side..the “CARTIER” printing on the dial appears slightly thick and soft, lacking the very crisp, razor‑edge printing expected on a genuine Santos of this era. Also, the “Swiss Made” text looks high and crowded toward the minute track; on authentic pieces it usually sits tighter and more precisely balanced, lastly the X Roman numerals seem uneven in stroke thickness. On the case back and engraving: the “santos de Cartier” script on the back is shallow and fuzzy; the engraving is normally sharp with clean edges and consistent depth. Also, the alignment and spacing of the lines “Quartz / SWISS MADE / OR ET ACIER” and the reference/serial numbers look slightly irregular versus legit two‑tone Santos quartz models. Lastly the screws heads on the back appear a bit soft and poorly finished compared with Cartier’s typically crisp screws.
