Description
An elegant antique pocket watch case featuring a triple-hinged design. The inner cuvette is beautifully engraved in cursive, identifying the mechanical heart of the piece: a cylinder escapement with 10 jewel bearings. The frosted gold finish of the inner cover provided aesthetic appeal while protecting the delicate movement from dust. This style represents the refined transition from thick 19th-century 'turnips' to the sleeker dress watches of the early 20th century.
Key Features
Cylinder escapement (horizontal) design; 10 ruby jewel count; French cursive engraving; double-hinged back assembly.
Color & Finish
Pale yellow gold with a matte/satin frosted cuvette finish; high-polish silver-toned outer hinges and rims suggesting a mixed metal or worn rhodium/silver construction.
Hallmarks & Stamps
Engraved 'Cylindre 10 rubis' on the cuvette. Purity stamps likely located on the inside of the outer case back or on the pendant/bow (e.g., horse head for French 18K).
Dimensions Estimate
32mm to 40mm diameter (standard ladies' or small men's open-face pocket watch size)
Gemstones & Inlays
Movement contains 10 functional ruby jewels (indicated by '10 rubis'). No external gemstones visible.
Clasp & Closure
Hinged double-back case with a snap-fit cuvette (dust cover) and outer case. Movement is accessed via the side-mounted hinge.
Chain & Links
Not pictured; typically paired with an Albert chain or slide necklace. Rounded case rim with a reeded or smooth profile.
Craftsmanship Details
Hand-finished cuvette with engine-turned or frosted surface; precision-aligned hinges; hand-engraved nomenclature. The fitment reflects high-end late 19th-century industrial artistry.
Authentication Indicators
Traditional hand-engraving versus modern laser etching; high-quality hinge soldering; correct terminology for the era ('Cylindre'). Red flag: check for 'Metal' or 'Galonne' stamps which may indicate gold plate or base metal.
Origin & Maker
Likely Swiss or French manufacture. The French script 'Cylindre 10 rubis' is characteristic of continental workshops in the late 19th century.
Era & Period
Late Victorian / Belle Époque (circa 1880-1910)
Age Estimate
Circa 1890-1905, based on the cylinder escapement technology and script style.
Cultural Significance
A symbol of the burgeoning industrial middle class and the democratization of timekeeping during the late 19th century.
Condition Notes
Good to Very Good. Noted surface scratches on the cuvette; some patina and oxidation on the internal hinges. Structural integrity of the hinges appears intact. Wear grade is consistent with careful handling over a century.
Value Estimate
Melt value $400-$700 (if solid gold); Collector value $850-$1,200 depending on movement functionality and hallmark verification.
Care & Maintenance
Clean with a soft dry cloth only; avoid ultrasonic cleaning as it can damage the movement; store in a dry environment; avoid all contact with water or humidity.

Interesting Facts
The 'Cylinder' escapement was invented by Thomas Tompion in 1695 and perfected by George Graham, allowing watches to be much thinner than the earlier verge escapements.
