ART DECO NAPOLEON HAT MANTEL CLOCK WITH TWO-TRAIN MOVEMENT AND WINDING KEY: IDENTIFICATION

Mid-20th century 'Napoleon Hat' style mantel clock featuring a dark-stained oak case with cross-banded veneer accents. The circular dial is protected by convex glass, exhibiting significant age-related yellowing and a vertical fracture. The two winding arbors on the dial face indicate a two-train movement, likely a bim-bam or cathedral coil strike mechanism. Chrome-plated bezel and stylized decorative escutcheons flank the central face. A single double-ended steel winding key is present.

Compare with other items in the archive: Mathurin Moreau (French, 1822–1912) - Andromeda, Bronze Figural Sculpture, American Oak Sideboard or Dresser with Serpentine Front - c.1890-1910, Silver Figural Sardine Fork with Barley Twist Stem.

ANTIQUARIAN'S ASSESSMENT

Vintage Technology Restorer & Historian

Tech Historian

The object is a very standard and well-documented form of 20th-century horology. Confidence is high regarding the era and type, though the lack of a visible maker's mark on the dial prevents a more specific attribution.

KEY EVIDENCE

  • 1Napoleon Hat case geometry is consistent with 1930s-50s production
  • 2Two winding arbors at the 4 and 8 o'clock positions confirm a striking movement
  • 3Convex glass fracture and dial foxing indicate long-term exposure to varying humidity
  • 4Chrome bezel and escutcheons are typical of the shift away from brass in the late Deco era

UNCERTAINTIES

  • •Cracked dial glass represents a safety hazard and significantly reduces value
  • •Internal corrosion is likely given the visible oxidation on the dial face

WHAT WOULD IMPROVE CERTAINTY

  • →Open the rear access door to identify maker marks on the backplate of the movement
  • →Inspect the movement for a 'deadbeat' or 'anchor' escapement to further refine the date
  • →Verify if the strike hammer still strikes a gong or coil without jamming

CONDITION & GRADE

Condition

Structural damage is present on the dial glass in the form of a vertical crack. The dial face exhibits significant environmental yellowing and staining. Surface abrasions are visible on the wood near the left escutcheon.

Weight & feel

Estimated weight ranges from 2.5 to 3.5 kg, suggesting a cast-iron or heavy brass movement frame housed within a solid wood and plywood laminate case.
