WW1 British Canadian Trench Watch Cover

The WW1 British Canadian Trench Watch Cover is an accessory designed to protect military wristwatches during the First World War. Produced for British and Canadian service members, this cover typically features a metal construction—often brass or nickel-plated—with a wire guard or grill across the face. The purpose of the cover is to shield the glass crystal from impacts, mud, and debris common in trench conditions, while still allowing the wearer to read the time. The cover is fitted with a hinged mechanism or a spring clip to securely attach it over the watch case. Such items were commonly used by officers and other personnel who relied on wristwatches for timing operations and coordinating maneuvers. The design reflects period-specific adaptations to the challenges of warfare, as watches evolved from pocket to wrist models. Trench watch covers are considered collectible due to their association with early twentieth-century military equipment.
