Patek Philippe Calatrava Ref. 3512 – Ultra-Thin White Gold Roman Dial Classic

Elegant, discreet, and technically refined, the Patek Philippe Calatrava Ref. 3512 represents the maison’s pursuit of pure, ultra-thin dress-watch perfection. This rare 18k white gold variant is especially coveted, combining precious-metal minimalism with a beautifully preserved original Roman-dial layout.

Ultra-Thin White Gold Case – Minimalism in Its Purest Form

One of the defining strengths of the Ref. 3512 is its incredibly slim profile: only 5.2 mm thick including the glass. This ranks it among the thinnest vintage Calatravas ever produced, gliding effortlessly under any cuff.

The case is made of solid 18k white gold, a far rarer configuration than the yellow-gold models more commonly seen. The metal lends the watch a crisp, modern, understated appearance that fits seamlessly into both contemporary and classic wardrobes.

Key proportions:

• 31 mm diameter

• 16 mm lug width

• Iconic ultra-thin silhouette

• Warm, perfectly vintage Plexiglass crystal

• Patek Philippe signed crown

Original Silver Roman Dial – Classical & Tastefully Aged

This example retains its original untouched silver dial, featuring:

• Fine sunburst finish

• Elegant printed black Roman numerals

• Slim pencil-style hands

• No date, no complications—just balanced Calatrava purity

Importantly, the dial shows minor, even patina around the outer edges, adding character without compromising cleanliness or symmetry. This light peripheral ageing is consistent with well-preserved vintage Patek pieces and confirms its originality.

The overall presentation remains bright, harmonious, and unmistakably refined.

Calibre 175 – Ultra-Thin Geneva Seal Excellence

Housed inside is Patek Philippe’s Calibre 175, an ultra-thin, hand-wound movement stamped with the prestigious Geneva Seal.
It is admired for its:

• Elegant construction

• Slim architecture tailored for ultra-thin cases

• Smooth winding action

• Outstanding reliability and accuracy

A perfect mechanical match to the watch’s discreet, minimalist design.

Strap & Buckle

The watch comes fitted with a black leather strap paired with a standard stainless steel buckle—a clean, classic pairing that suits the Calatrava’s understated aesthetic beautifully.
