Very rare and original Longines Weems SAAF (South African Air Force) Mk VIIA wristwatch c.1940.
These watches are extremely rare as only around 2,500 were issued to the RAF at the outbreak of hostilities during World War Two and many will have no doubt seen action during the early dark days of the Battle of Britain and beyond.
The watch was issued to pilots and navigators and features a moveable outer bezel which is set to the seconds hand to calculate longitude in order to aid navigation.
The Weems watch takes its name from Lt.Cdr P.V. Weems who was a well know aviator, navigator and instructor at the Naval Officer School at Annapolis, Maryland, in the U.S.A.
The example for sale is rarer still as it was subsequently re-issued to the South African Air Force. This is indicated by the additional markings “AF1410” and down arrow within a U shape on the case back. We have only ever seen one other Longines Weems watch SAAF example such as this and consequently the watch for sale represents a truly unique opportunity to acquire a superb piece of aviation history.
