Silver-toned open-face pocket watch with Elgin-branded dial

This item is an open-face pocket watch featuring a silver-toned metal case and a decorative chain, presented in a vintage display box. The dial is white with black Arabic numerals and bears the name 'ELGIN' below the 12 o'clock position. It utilizes a three-hand configuration including a small seconds sub-dial located at the 6 o'clock position; the hands appear to be blue-steeled in a spade and whip style. The case edge shows intricate scrolling or engine-turned engraving, consistent with early 20th-century decorative styles. The presented box is lined with cream-colored satin and bears the printed text 'The Halle Bros. Co. THE MENS STORE BY KREMENTZ'. Physically, the watch shows significant signs of age, including heavy spotting/oxidation across the dial face and some dulling of the metal surfaces. While the markings suggest an Elgin movement and a Krementz-related retail origin, these attributions remain hypotheses pending an internal inspection of the movement and case back for serial numbers or hallmarks. The overall aesthetic is consistent with American pocket watches manufactured between 1910 and 1930.

I have examined the provided image of the silver-toned open-face pocket watch. Based on what I can see, the dial bears the name 'ELGIN' and the presentation box is associated with The Halle Bros. Co. and Krementz. I am treating the attribution to the Elgin National Watch Company as a working hypothesis, as I cannot verify the movement serial number or case material hallmarks from a photo. The watch features a spade-and-whip hand configuration and a sub-seconds dial consistent with early 20th-century American production, likely between 1910 and 1930. The value is significantly impacted by the visible condition; I observe heavy spotting and oxidation on the dial and dulling of the case. While the presence of the retailer-branded box adds some historical interest, the overall condition is considered 'fair' at best. My estimate of $75 to $150 assumes the identification is correct and the case is a base metal or silver-filled alloy. If the case were confirmed as solid silver through physical testing, the value would increase. Conversely, if the internal movement is found to be non-functional, damaged, or a later replacement, the value would likely drop to a range of $20 to $40 for parts. A physical inspection by a watchmaker is required to confirm the movement's grade, verify the case composition, and check for any internal signature or hallmark that would support the hypothesized origin. General market demand for common Elgin models in this condition remains stable but modest among entry-level horological collectors.
