This large Santos-Dumont reference W2SA0028 houses a quartz movement within a steel case measuring 43.5 mm × 31.4 mm with a thickness of 7.3 mm. The yellow gold 750/1000 bezel frames a grey satin-brushed dial rendered with a sunray effect, golden Roman numerals, and polished golden-finish steel sword-shaped hands. A beaded crown set with a synthetic blue cabochon-shaped spinel adds a signature Cartier touch, while a sapphire crystal protects the dial.
The watch rides on a grey alligator-skin strap secured by a steel ardillon buckle, lending an understated elegance to the bold rectangular case proportions. Water resistance is rated to 3 bar (approximately 30 metres).
