Chinoiserie-style floor clock bearing Reguladora markings

This is a tall case clock, commonly referred to as a grandfather clock, appearing to be finished in a black lacquer with extensive gold-toned Chinoiserie and geometric ornamentation. The crown features a pagoda-style silhouette decorated with a hand-painted scene of mountains and architecture. The wooden case is further embellished with gold scrollwork and floral motifs. The dial assembly contains a centrally located face with Roman numerals and an intricate filigree center disc. Visible text on the dial includes 'Reguladora' and 'Made in Portugal'. Above the main dial is a smaller sub-dial with a selector hand pointing to text reading 'Westminster' and 'Ave Maria', suggesting a dual-chime movement. The owner identifies this as a 'Reguladora west minister Ave Maria grandfather clock', which is unverified but consistent with the visible face markings. Construction features include fluted pillars with gold-toned capitals and a glass-enclosed dial hood. The decorative style is consistent with mid-to-late 20th-century European interpretations of traditional motifs. While the craftsmanship appears detailed, the attribution to the Portuguese maker Reguladora is based solely on unverified dial markings and stylistic consistency with their output from that era. No physical inspection of the internal movement has been performed to verify its origin or condition.

Based on my visual review of the image provided, this tall case clock is designed in an elaborate Chinoiserie style characterized by black lacquer and gold-toned ornamentation. Per user submission, the item is attributed to the Portuguese manufacturer Reguladora and is described as a 'Westminster Ave Maria grandfather clock.' The dial bears markings consistent with this maker and suggests a dual-chime movement; however, I cannot verify the internal mechanical components or the case materials from a photograph alone. This estimate assumes the clock contains a functioning, high-quality Reguladora movement and that the decorative finish is in good condition with minimal loss to the hand-painted detailing. The market for mid-to-late 20th-century decorative floor clocks remains steady for pieces with unique aesthetic appeal, though demand for large-scale traditional clocks has fluctuated. I have based this value on what such an item might achieve at a specialized furniture or decor auction, assuming the attribution is correct. Because I cannot perform a physical inspection to check for manufacturer stamps on the movement or verify the age of the lacquer work, this attribution remains a hypothesis. If the piece were found to be a more modern mass-produced reproduction using synthetic materials or a standard quartz movement rather than the mechanical movement suggested by the dial, the value would likely decrease to the $200–$400 range. To establish a more precise valuation, a physical examination by a horologist is necessary to inspect the movement’s state, verify the 'Made in Portugal' hallmarks, and assess the degree of hand-painted versus stenciled ornamentation.
