Housed in a 42.1mm steel case measuring 13mm in thickness, this Ballon Bleu de Cartier features the model's signature fluted crown set with a synthetic spinel cabochon. A sapphire crystal protects the silvered guilloché dial, which is appointed with Roman numerals and blued-steel sword-shaped hands. A calendar aperture sits neatly at the 3 o'clock position.
Power comes from a mechanical movement with automatic winding, offering a self-sustaining caliber well suited to everyday wear. The watch carries a water resistance rating of 3 bar, equivalent to approximately 30 meters or 100 feet.
Completing the presentation is an alligator-skin strap fastened by a double adjustable folding steel buckle, lending the piece a supple, comfortable fit. Reference W69016Z4 represents the Ballon Bleu collection in a versatile 42mm configuration built for those who appreciate Cartier's longstanding dedication to considered design.
