OW M-110 AS

In the absence of a magnetic compass, the US Army Ranger Handbook provides infantrymen with detailed instructions on how to use the watch method to get a bearing. This is a simple technique that involves lining the hour hand up with the sun, and then bisecting the distance between the hour hand and the 12 o’clock position to discover south. Another distinctive feature of the OW M-110, which military users will recognise, is the radio silence period markers on the dial. These are three-minute periods immediately after each quarter hour, reserved exclusively for making – and listening for – distress calls.
