Measuring 43.5 x 31.4 mm, the Santos-Dumont large case is rendered in stainless steel and framed by an 18K yellow gold bezel that introduces a warm contrast to the two-tone composition. Exposed screws on the bezel remain true to the shape first conceived in 1904, while a sapphire crystal protects the dial above. The steel crown is set with a blue sapphire cabochon — a characteristic Cartier touch carried throughout the collection.
On the white dial, Roman numerals provide clean legibility alongside blued-steel sword-shaped hands. Time-only display — hours and minutes — is driven by a quartz movement, keeping the watch straightforward to live with day to day. Water resistance stands at 30 meters, suitable for the demands of everyday wear.
A brown alligator leather strap secured by a steel ardillon buckle completes the reference, lending warmth that works well with the gold bezel. The WGSA0036 is presented with its original Cartier box and papers, making it a complete example of this enduring rectangular icon.
