Notes
Pocket Watch Chronograph movement adapted for use as a navigation instrument. Similar watches produced for military specification A-7 also made by AR & JE Meylan and Gallet. 175 were originally ordered from Longines. A small run of civilian market watches were released using spare movements after the war in steel cases rather than mil-spec base metal ones.
