Reichs-Luftwaffe 'Imperial Air Force'
The Imperial Air Ministry (RLM) was founded by Hermann Goering who was in control of it. In this way it was not influenced by the more conservative war ministry, which was not loyal to the Nazi leaders, but whose Generals held with the Prussian tradition of loyalty to the state and not to a person. The air ministry demanded the development of aircraft clocks partly with chronograph functions, big pilot navigation wristwatches (55mm diameter) with pocket watch movements and a central second hand, as well as pilot chronographs. The first navigation wristwatches (B-Uhren) experimented with the central second by derivation of pocket chronograh movements (Valjoux 61 or Longines). These were marked 'RLM' with the number on the bottom. These early watches had a push button for the positioning of hands. There were single pieces with grade angle dial (Lange) or even rare examples of Patek Philippe or Vacheron & Constantin. The latter serial types had two different dials: normal hour hands and minute hands, or a small hour dial and a big minute dial. They were classified with 'FL 23883'.

The earliest known origin of the Navigator’s watch came in the form of the Longines Weems second-setting watch. This was created by Lt Commander Philip Van Horn Weems in conjunction with Longines, and had a rotating center seconds dial and a 48mm diameter case. This watch was patented in 1929 and went into production.

In the 1920s and 30s there were a plentiful number of pilot's wristwatches, mostly with chromed or nickel cases, with broad clips for the strap and screwed or angled back. I know some items with unknown or fantasy brands, but most were known Swiss manufacturers like Omega, Longines, Zenith.
