Type

Dress Watch / Art Deco Wristlet

Brand

Bulova (formerly J. Bulova Company). Historically a Tier 1 American-Swiss luxury/premium manufacturer during the early 20th century.

Movement

Manual-wind mechanical movement. Likely a Bulova Caliber 10AN or 10AE, typically featuring 15 to 17 jewels and a frequency of 18,000 bph with approximately 30-40 hours of power reserve.

Dimensions

Diameter: ~26mm to 30mm (excluding crown); Thickness: ~9mm; Lug-to-Lug: ~35mm; Lug Width: ~16mm. This is a very small 'unisex' or men's vintage size compared to modern standards.

Description

A classic example of early 20th-century horology, this Bulova Tonneau captures the transition of the wristwatch from a novelty to a tool of elegance. The 'barrel' shape was a rebellion against the circular pocket watches of the past, offering a contoured fit on the wrist. Despite its heavy patina, the 'Exploding' numerals and sub-seconds register remain hallmarks of a sophisticated era of design.

Key Features

Tonneau case shape, 'Exploding' Arabic numerals, sub-seconds layout, hooded lugs, and high-domed acrylic crystal.

Dial Description

Aged silver/champagne tone with significant patina. Features 'Exploding' Arabic radium numerals and a rectangular/square sub-seconds dial at 6 o'clock. The hands are thin blued-steel or painted syringe/leaf style.

Case Material

Gold-filled or Gold-plated (likely 10K or 14K RGP). The visible wear and greenish oxidation suggest a base metal or brass interior. The finish was originally high-polish with engine-turned or 'stepped' detailing on the lugs.

Crystal Type

Acrylic/Plexiglass (High-domed). Highly scratched and clouded with visible yellowing and potential cracks due to age.

Bezel Details

Fixed integrated bezel, part of the tonneau case structure. Features decorative 'steps' at the 12 and 6 o'clock positions where the case meets the strap/bracelet.

Crown & Pushers

Small, knurled push-pull crown at 3 o'clock. Likely unsigned or featuring a simple cross-hatch, as was common for the 1920s/30s.

Bracelet or Strap

Missing. The watch features fixed bars or hooded lugs designed for a leather strap or a vintage 'Expansion' or 'Mesh' metal bracelet.

Caseback Details

Solid, snap-on caseback. Likely engraved with 'Bulova', a serial number, and a date code symbol (e.g., triangle, circle, or square) once cleaned.

Movement Type

Manual-wind mechanical movement. Likely a Bulova Caliber 10AN or 10AE, typically featuring 15 to 17 jewels and a frequency of 18,000 bph with approximately 30-40 hours of power reserve.

Water Resistance

Non-existent. This watch has no gaskets or screw-down components; even high humidity or a splash of water could further damage the movement and dial.

Origin & Provenance

American Brand / Swiss Movement (Ebauche). Parts were often manufactured in Switzerland (Bienne) and cased/timed in the USA (New York).

Age Estimate

Circa 1927–1934. The dial layout and case geometry are diagnostic of the peak Art Deco production years.

Cultural Significance

Representative of the 'Golden Age' of American watches. These timepieces transitioned the industry from military-focused trench watches to civilian luxury items.

Condition Notes

Poor. Significant environmental damage, heavy dial oxidation (green 'verdigris' likely from moisture and radium interaction), scratched/clouded crystal, and worn plating. Grade: Poor/Restoration Candidate.

Value Estimate

$30 - $75 in its current 'as-is' condition. Fully restored examples can fetch $250 - $450 depending on the specific model rarity and gold content.

Care & Maintenance

Requires a full movement overhaul. Do not attempt to wind if the movement is seized. Radium lume used on the dial is radioactive; avoid opening the case or inhaling dust from the dial/crystal. Store in a dry environment.

Similar Watches

Hamilton Piping Rock, Elgin Legionnaire, or Illinois Picadilly. These competitors offered similar tonneau shapes but differed in lug design and movement architecture.

Interesting Facts
