Longines developed these simple, high-quality watches in the 1930s in Saint-Imier, Switzerland. These were Longines’s first waterproof models, intended for heavy use. The crown was large in size and the crown tube was sealed. The crystal was attached to a deep groove on the case, and the screw-back case back was locked into place using a lead gasket. The three locking notches (tre tacche) on the case back are the most recognizable feature of these models. This model houses the well-known, high-quality Longines cal. 10.68Z movement.
