Trench Watch with Bund-Style Leather Strap

This is a vintage 'trench' style wristwatch, a transitional timepiece design from the early 20th century (circa 1910s-1920s) that converted pocket watch movements for wrist wear. The watch features a white enamel or ceramic dial with bold, stylized black Arabic numerals and a sub-dial at the 6 o'clock position for seconds. The brand name 'Waltham' is partially visible on the upper quadrant of the dial. It is housed in a polished nickel or silver-toned metal case with a distinctive oversized onion-style winding crown. The watch is mounted on a wide, thick brown leather 'Bund' or 'trench' strap, which was originally designed to protect the wearer’s skin from extreme temperatures and to protect the watch from moisture. The strap shows significant signs of age and patina, with darkening of the leather and visible stitching. Condition-wise, the dial exhibits some minor discoloration or 'foxing' near the numerals, and the case shows light surface scratches consistent with age. This piece exemplifies the craftsmanship of early portable timekeeping, transitioning from the Victorian era to the utilitarian needs of World War I.

This Waltham 'Trench' watch represents a significant era in horological history, marking the transition from pocket to wrist-worn timepieces. Upon my visual examination, the dial appears to be an original enamel or porcelain disc; the minor foxing and aged patina are consistent with a vintage of circa 1915-1925. The cathedral-style hands and bold Arabic numerals suggest a military-inspired utility, and the 'onion' crown is a desirable period-correct feature. The inclusion of a wide Bund-style leather strap, while likely a high-quality reproduction or later addition, adds significant aesthetic value and historical context. Current market demand for WWI-era 'trench' watches remains steady among niche horology collectors, though values are heavily dependent on the movement's functionality and case material (e.g., silver vs. nickel). Comparables for a working Waltham nickel-cased trench watch typically range from $400 to $800 depending on the movement's grade. Factors limiting the value include the visible dial discoloration and the lack of visibility regarding the movement's caliber and service history. Note: This appraisal is based solely on high-resolution imagery. Full authentication requires an in-person inspection to verify the hallmarkings on the inner case back and to examine the serial number on the movement, which would confirm the exact production year. To finalize this valuation, I would need to observe the movement's balance wheel oscillation and verify the absence of hairline cracks in the enamel dial under 10x magnification.
