Water Resistance
120 Meters (12 ATM). Suitable for swimming and snorkeling, though the crown must be fully screwed down to maintain integrity.
Origin & Provenance
Swiss Made; Manufactured in Geneva, Switzerland. Fully in-house movement and case production.
Age Estimate
Circa 2010–2021 based on the blue dial saturation and lack of the 'Tiffany & Co.' stamp.
Cultural Significance
It redefined the concept of luxury by proving that a steel watch could be just as prestigious—and more expensive—than solid gold timepieces. It is a staple among A-list celebrities and financial titans.
Condition Notes
Visually appears in excellent condition with sharp bezel edges; polished center links on the bracelet shows high reflectivity suggesting minimal wear or professional upkeep.
Value Estimate
Secondary market value ranges from $75,000 to $120,000 USD depending on year and completeness (box/papers). Discontinued status maintains high demand.
Care & Maintenance
Service every 5 years; water resistance gaskets should be pressure tested annually. Avoid wearing during high-impact sports despite the 'sport' designation due to the movement's sensitivity.
