Patek Philippe - Calatrava 3520 ‘Slate’
Slate 🤍 Elegance
An 18k white gold Patek Philippe ref. 3520 — an elegant Calatrava form, here with an exceptionally rare grey sunburst dial and white Roman numerals. At 32mm and powered by the hand-wound calibre 177, it’s paired with a refined Japanese steel bracelet that complements its quiet sophistication.
The case shows gentle wear yet retains strong hallmarks; the dial, a touch of oxidation visible only under certain light, adds character rather than flaw. Produced from the late 1960s to early 1980s, the 3520 remains one of Patek’s most timeless and architectural designs.
