Very rare Waltham “Giant 6-Size Trench” men’s Military design wristwatch in yellow gold fill, circa 1917.

Giant 6-size trench watches are very rare in gold fill and this is one of only a handful known to exist, all cased by Bates & Bacon of Philadelphia.  The case is in crisp, excellent condition with no brassing. Caseback is excellent and unengraved, with some scratches. Original enamel dial is superb with no cracks. Case measures 42mm long and 38mm wide. Has new glass crystal. This watch is powered by its correct 15-jewel Waltham Seaside grade manual wind movement, just serviced and running strong.
