The Cartier Tank Allongée reference W15329U3 is a ladies' wristwatch rendered entirely in 18K white gold. Its rectangular case measures 14.5 × 28 mm and is fitted with a scratch-resistant sapphire crystal, beneath which the white dial displays bold Roman numeral hour markers alongside slender blued-steel sword-shaped hands indicating hours and minutes.
Driving the watch is a quartz movement, delivering reliable timekeeping within the Tank's characteristically slim profile. The fixed bezel and clean dial layout speak to the model's longstanding place in Cartier's design vocabulary. The 18K white gold bracelet fastens securely via a hidden fold-over clasp.
This example is Swiss made, dates to 2007, and is offered in used condition with its original box and original papers included.
