Delicate timepieces had no place in the harsh environment of the trenches. The Waltham Watch Company of Massachusetts developed a model much like this one as effective insurance against cracked and scratched crystals. World War I Military Watch is constructed with a caged stainless steel case, an oversized crown, and outfitted with a rugged leather-backed canvas band. Mineral crystal, quartz movement. Case diameter 40mm. Water resistant to 165 feet. Imported.
