Cartier Tank Must de Silver Blue Roman Dial PM w/ Cartier Service 2026 Ref 666001 From 1980s

An elegant and uncommon Cartier Tank Must de Silver Ref. 666001 in the classic PM size, crafted in solid .925 sterling silver rather than the more commonly encountered vermeil finish. Recently fully serviced by Cartier, this is a beautifully preserved example ready to be worn and enjoyed.

The classic 20 × 28 mm case is made from .925 sterling silver and remains in wonderful condition. Its clean white dial features striking blue Roman numerals, perfectly complemented by traditional blued steel hands and a newly fitted blue sapphire cabochon crown.

Inside is the Cartier Calibre 157 quartz movement, which received a complete service at Cartier Boutique Brussels in 2026. The total intervention amounted to €517, comprising a €430 complete service, a new screw (€20) and a new sapphire crown (€67).

The watch is accompanied by its Cartier service paperwork, Cartier service pouch and the valuable 2-year international Cartier service warranty, offering excellent peace of mind to its next owner.

It is currently fitted with a black leather strap and a generic steel pin buckle.
