Chaumet Pebble "Jump Hour" 10A - Yellow Gold

The "Hidden" Pedigree of François-Paul Journe

The Chaumet Reference 10A is a "holy grail" for collectors of 1990s neo-vintage design. While Chaumet is a legendary Parisian jeweler, the mechanical soul of this watch is rooted in elite independent watchmaking. This model was developed during the era when a young François-Paul Journe was commissioned by Chaumet to design their complicated timepieces. Owning a 10A is, in many ways, owning a piece of Journe’s early creative history, before he became a global icon of haute horlogerie.

The "Disco Volante" (Flying Saucer) Aesthetic

The 36mm case is an 18K yellow gold masterpiece of geometry. Known by collectors as a "Disco Volante" or "Pebble" case, its lugless, circular design creates a seamless, coin-like profile on the wrist. Because the lugs are hidden beneath the gold "mask" of the case, the watch sits perfectly centered and exceptionally thin. This minimalist architecture allows the focus to remain entirely on the unique way the watch communicates time.

Art Deco "Digital" Mystery

Unlike a standard watch where hands sweep across a dial, the 10A utilizes an aperture-based "Jump Hour" system. The top window displays the hour, which remains stationary until the exact top of the hour, then instantly "jumps" to the next digit. The bottom window features a rotating disk for the minutes. This "digital" mechanical layout is a direct nod to the Art Deco mystery watches of the 1920s, offering a secretive and highly symmetrical dial that prioritizes art over traditional handsets.

Curated Preservation and Style

This example is in very good condition, retaining its original Chaumet branded black leather strap with 18K yellow gold pin buckle. Inside, the modified Calibre 2892-2 automatic movement provides the necessary torque to power the instantaneous hour jump. It's a rare, high-character timepiece for the collector who values design history and independent DNA.
