This 37 mm model offers a harmonious balance of elegance, technical refinement, and everyday wearability.
Crafted in stainless steel, the 37 mm case features the signature rounded Ballon Bleu silhouette with a polished finish, giving the watch a refined and elegant wrist presence. The integrated stainless steel bracelet complements the case, providing comfort and a seamless visual flow. The crown, set with a blue synthetic spinel cabochon, remains a defining feature of the Ballon Bleu collection.
The dial presents a silvered finish with Roman numerals, blued steel sword-shaped hands, and a delicately integrated moonphase display at 6 o’clock, adding both visual interest and horological complexity. The elegant layout ensures excellent legibility while preserving the refined aesthetic synonymous with Cartier.
This timepiece is powered by an automatic mechanical movement, ensuring reliable performance and a smooth operation suitable for daily wear. The precision and robustness of the movement reflect Cartier’s commitment to quality and enduring craftsmanship.
