Rolex Precision “Disco Volante” Ref. 9522 – 18K Yellow Gold UFO Case, Grey Ghost Dial (1950s)

A rare and delightfully unconventional piece from an era when Rolex produced far fewer watches and experimented boldly with design, the Rolex Precision Ref. 9522—nicknamed the “Disco Volante” (Flying Saucer/UFO)—stands as one of the most distinctive mid-century Rolexes ever made.

With its lugless case, domed crystal, ghost-grey dial, and engraved bezel, this late-1950s beauty captures a unique chapter in Rolex history, before the brand became the global icon it is today.

UFO / Flying Saucer Case – A Bold 1950s Experiment

The 36 mm case is crafted entirely in 18k yellow gold and exhibits the iconic “Disco Volante” profile:

• No external lugs – the strap integrates inside the case

• High domed Plexiglass crystal, enhancing the UFO silhouette

• Wide, rounded case sides that give it a floating, sculptural presence

• Hour–minute engraved bezel, a rare and very cool design detail

• No signs of polishing, preserving the crisp factory geometry

This design was a short-lived experiment by Rolex, making surviving examples remarkably scarce today.

Original Grey Ghost Dial – Pristine & Highly Collectible

One of the highlights is the exceptionally preserved original Rolex “grey ghost” dial, in pristine condition, featuring:

• Rich shifting grey tone

• Applied gold indices

• Alpha hands – characteristic of early examples

• Small running sub-seconds at 6 o’clock

• Rolex coronet at 12

• Clean printing and flawless surface

This dial variant is rare and highly sought after, especially in such untouched condition.

The watch retains its original Rolex signed crown, completing the period-correct aesthetic.

Rolex Calibre 1000 – Early Manual-Wind Excellence

Inside sits the Rolex Calibre 1000, a reliable and finely finished hand-wound movement used in early Oyster and Precision models.

Paired with a serial number 651,399, the watch dates firmly to the late 1950s, aligning perfectly with the alpha hands and UFO case period.

Original Strap & Buckle – A True Time Capsule

A remarkable detail: this watch still features its original Rolex leather strap, an extremely rare survival more than 60 years later.

It also retains its original 18k yellow gold Rolex buckle, matching the case and adding tremendous collector value.

These original accessories elevate the piece into true museum-grade territory.
