The steel A7 Avigation ref. 3592


Extremely rare steel Longines A7 “Avigation” chronograph, manufactured in 1937.

Launched before World War II, these single pusher chronographs were initially produced for aviators only. The dial was set at an angle so the time could be easily read while piloting. Also, a single button pusher incorporated into the crown allowed the pilot to easily start, stop and reset the chronograph.

The Longines “A7 Avigation” name comes from the US Army Air Corps “Type A” designation of many of their issued equipment watches and derives from the conjunction of “Aerial Navigation”.  After the war and for a very short period of time, a small production in stainless steel – as the present one – was made for the civilian market as opposed to the chrome-plated military version.

The present stainless steel civilian A7 is preserved in amazing original condition. The black matte dial is enhanced by the gilt writings. The gilt finished movement is superbly preserved. The beauty and rarity of this historical oversized steel Longines chronograph is extraordinary.

Accompanied by the Longines “Extract from the Archives” confirming that this specimen was invoiced on 4th of December 1937 to Hans Erich Lochner in Bathurst Canada, who was at that time a flight captain for the German company Lufthansa.
