WWI Era American Trench Style Pocket Watch I TP Dial Manual c1917–1920 Working

An authentic early 20th century American trench-style military watch, dating to the World War I period or immediate post-war years (circa 1917–1920). This watch features a black military-style dial marked “I TP”, Arabic numerals with aged luminous infill, and a subsidiary seconds dial at 6, all characteristic of WWI trench and utility timepieces produced for military and industrial use. The watch winds smoothly via the top crown and ticks loudly, indicating it is currently running. Timekeeping accuracy has not been tested over an extended period and, as with all vintage mechanical watches, it is sold as a collectible rather than a precision instrument. During World War I, wristwatches were still evolving and many soldiers relied on compact pocket or trench-style watches designed for durability, legibility, and rapid mass production. - The “I TP” dial marking is consistent with Type I Trench Pattern dials seen on WWI-era American military and quasi-military watches - The simple, non-hacking manual wind movement, lack of shock protection, and subsidiary seconds layout all point to pre-WWII manufacture - Both the movement and case are stamped “MADE IN U.S.A.”, aligning with American wartime production rather than later WWII government contract watches - Serial numbers present on the movement and case further support early 20th century mass manufacture, rather than post-1940 military standardisation This watch is not presented as officially issued, but as a period-correct trench-style watch of the type widely used by servicemen during the WWI era. - In working order at time of listing - Winds and ticks clearly - Honest age-related wear throughout - Scratches and patina to case and glass - Dial shows wear and fading consistent with age but remains legible - Please study all photographs carefully as they form part of the description Measurements - Approx 5cm diameter excluding crown
