An heavily modified Cartier Santos 'Large' that transforms a historic tool watch into a high-octane piece of jewelry. This watch features the classic Santos silhouette, originally designed for Alberto Santos-Dumont in 1904, but completely iced out with diamonds across the case, bezel, and dial. The addition of rainbow-colored hour markers provides a vibrant, contemporary contrast to the monochromatic shine of the diamonds and white leather strap.

Full diamond pavé aftermarket dial featuring custom multi-colored rainbow indices (likely sapphire or garnet mix), sword-shaped hands, and a date window at 6 o'clock.

Water Resistance
Original rating 100m (10 bar). Recommended: Treat as splash-resistant only due to potential modifications to the case integrity during diamond setting.
Origin & Provenance

Age Estimate
Modern generation (2018–2024), likely manufactured within the last 5 years based on the dial layout and case shape.
Cultural Significance
Represents the intersection of classical horology and modern luxury 'flex' culture. While respected by purists in its original form, this diamond version symbolizes status, success, and high-fashion visibility.
Condition Notes
Visually Good. Case settings look intact, though aftermarket stone settings can vary in quality. The strap appears clean and the crystal shows no major chips. Overall: Very Good (Customized).
Value Estimate
Secondary Market: $15,000–$25,000 USD (Value varies wildly based on diamond quality/carat weight and if original parts are included). Note: Aftermarket modifications usually void Cartier factory warranties.
Care & Maintenance
Service every 5-8 years. Ensure stones are checked for tightness regularly. Avoid water immersion as aftermarket setting can compromise original gaskets. Clean with a soft brush and mild soap.
