Anniversary mantel clock, bears text reading 'Concordia' (not authenticated)

This is a tabletop anniversary style torsion pendulum clock, frequently referred to as a four-hundred-day clock, housed beneath a clear domed enclosure. The item features a polished brass-tone metallic base and matching structural frame components, surmounted by an ornate, scrolled top arch above the circular clock face. The dial is off-white or cream-colored, decorated with a delicate floral garland border encircling the minute track and black Arabic numerals marking the hours. The hands are dark blue or black in color with an ornate filigree design on the hour and minute hands. Visible beneath the dial are four rotating spherical brass-tone pendulum balls that comprise the characteristic torsion suspension mechanism of this clock type. The protective dome appears to be clear acrylic or glass, resting securely on the stepped metallic base. Regarding condition, the metal surfaces display a generally bright finish with minimal visible tarnishing or surface wear in the photograph, though close physical inspection would be required to assess any micro-scratching, mechanical functionality, or internal wear. The dial features legible text reading 'Concordia' in a script font. The owner has provided additional context, user-attributing the piece as 'Concordia'; however, this user-supplied claim remains unverified and is presented solely as provenance information. The style is consistent with mid-to-late 20th-century decorative mantel clocks manufactured to emulate traditional European torsion clocks. The identification of the brand rests entirely upon the printed text visible on the dial face, which is unverified regarding authenticity.

Based on what I can see in the photograph, this is a mid-to-late 20th-century anniversary-style torsion pendulum clock featuring a polished brass-tone finish, a floral-accented dial, and a protective dome enclosure. The dial bears text reading 'Concordia' in a script font. The owner identifies this as a Concordia piece, but per user submission, this attribution remains unverified and is treated solely as a working assumption. I cannot verify from a photo whether the internal mechanical components are fully functional, nor can I determine the precise metal composition or detect micro-scratching without physical inspection. My value estimate of $75 to $150 assumes that the piece functions properly and that the 'Concordia' text corresponds to the maker associated with this style of decorative clock. General market demand for vintage torsion clocks of this era is relatively modest, as they are commonly produced decorative items rather than rare horological antiquities. If the clock turns out to be a reproduction, an unbranded copy, or made 'in the style of' rather than by the named brand, the value would likely decrease to the $30-$60 range, as buyers generally value working condition and aesthetic appeal over unproven brand association. To confirm authenticity and mechanical integrity, an in-person examination by a horologist, physical inspection of internal movements, and research into period manufacturing documentation would be required.
