Bidspirit auction | An Assortment of Four American

An Assortment of Four American Waltham Pocket Watch Movements for Parts - A collection of four antique mechanical pocket watch movements manufactured in Waltham, Massachusetts. The lot includes various iterations of the manufacturer's mark. One porcelain dial is printed in black with a serif wordmark reading A. W. Co. WALTHAM (photo 2). A second dial features a cursive script reading Am. Watch Co. WALTHAM (photo 4). A third dial bears the mark American Waltham W. Co. (photo 6), and a fourth is marked AMERICAN Waltham Watch Co. in a mixed font (photo 8). All four dials are white porcelain with Roman numeral hour markers and sunken sub-second tracks. The brass plates of the movements feature various engraved marks and serial numbers. One movement is engraved in a decorative script P. S. Bartlett WALTHAM, MASS. and bears the serial number 2491196 (photo 3). A second movement plate is engraved American Waltham Watch Co. with the serial number 3732959 and the words SAFETY PINION (photo 5). A third movement is engraved American Waltham Watch Co. with the serial number 6108039 (photo 9). The fourth movement plate is missing, revealing the interior brass wheels and pillars (photo 7). The movements are of the manual wind variety and appear to be size 18s based on the caliber. Each movement measures approximately 1 7/8 inches in diameter. This lot is in poor, non-working condition and is offered strictly for parts or restoration. All four porcelain dials exhibit significant damage, including heavy staining, multiple hairline cracks (crazing), and chips with enamel loss, most notably around the edges and center holes (photos 2, 4, 6, 8). The movements show heavy oxidation, surface corrosion, and a buildup of dust and debris (photo 10). Movement serial 2491196 is missing its balance cock and balance wheel assembly (photo 3). Movement serial 3732959 and 6108039 also appear to be missing balance components (photos 5, 9). The fourth movement is heavily cannibalized, missing its top plates and the majority of its internal components (photo 7). Only one dial retains its hour and minute hands (photo 6); all other hands are missing or detached.
