Palazzo trades the maison’s keepers: Santos, Tank, Ballon Bleu — cases honest, papers where stated, every piece examined against reference before it joins this page.
Cartier hides its proof in plain sight — a secret signature in the chapter ring, a sapphire in the crown. We check all of it, and we put what we find in writing.
Caliber read against the reference — finishing, engraving and screw quality. Quartz or mechanical, the inside must match the papers.
Roman chapter ring under loupe for the hidden CARTIER signature, printing crispness and hand bluing. Redials disclosed, never disguised.
Case hallmarks, crown sapphire (or spinel, period-correct) and bracelet stamps. Polishing graded honestly — sharp, light, or refinished.
Certificate, serial cross-reference and service history — documented on your invoice and the Palazzo certificate.
