Cartier Tank Must Large 33.7×25.5mm Diamond K11F White Dial Brown Smooth Calf

Engineered by K11 Factory (K11F) for collectors who care as much about what’s under the caseback as what’s on the dial, the Cartier Tank Must Large 33.7×25.5mm Diamond K11F White Dial Brown Smooth Calf pairs a Solid 316L Stainless Steel (Satin & Mirror Finished) exterior (25.5MM) with the cloned Calibre 1847 MC Automatic Clone movement (42-Hour Power Reserve (28,800 vph)).

Inside the Calibre 1847 MC Automatic Clone Architecture

The winding stem engages with a firm, positive click across every setting position, and the hands advance with zero backlash. Sealed behind a scratch-resistant sapphire crystal and triple-checked gaskets, it’s built for daily wrist rotation rather than sitting in a display box.
