Cartier Tank W4TA0009

The W4TA0009 represents Cartier's diamond-set interpretation within the Tank Française collection. This reference distinguishes itself through its diamond-set bezel configuration, positioning it as the luxury variant among Tank Française offerings. The 20.3mm x 25.4mm case dimensions place it in the smaller size category for this model line. The steel case construction features a diamond-set bezel paired with a silver opaline dial. A sapphire crystal protects the dial surface, while water resistance extends to 30 meters. The quartz movement provides the timekeeping function, and the watch pairs with a steel bracelet. Production commenced in 2015 and continues to present. This reference targets collectors seeking Tank Française styling with diamond detailing while maintaining steel case construction. The combination of precious stone setting with steel materials creates a middle-ground option between standard steel variants and fully precious metal configurations. The quartz movement and moderate water resistance reflect the dress watch orientation of this reference within Cartier's offerings.
