ATACAMA FIELD DAY DATE 1920 SERIES
Originating in the 1880's, the field watch gained popularity during the First World War due to soldier's demands for reliable and portable timepieces. Trench fighting required quick, accurate timing so watches had to be small enough to be worn on the wrist. The battlefield environment also created a need for exceptionally water and shock resistant watches, and the Field watch quickly evolved a distinctive style – rugged and utilitarian with virtually no embellishment.
