Hi Cathl
That is a you know a Longines 'WEEMS' watch. It was designed by Lieutenant Commander Weems. (US, Patent number:2008734)
Weems work in navigation became so important and invaluable, that he isa now known as the 'father of modern navigation.'

In 1930 Longines agreed to manufacture the 'weems' watch

Charles Lindenbergh used the 'weems' design on his famous flight. He then (Lindenbergh) took the basic design added scales to dial and bezel to calculate the hour angles of the sun, and stars. There By creating the 'Lindenbergh Longines Hour Angle watch'
That IS what you have. I never seen one before.

If you can give me the serial numberof YOUR watch, I will find out ALL the details about it for you.
Including exact manufacture date and to whom (and where) it was first sold.

Thanks for posting a very unusual watch.

Adam

Cathy you've got a very cool piece of history. If you do make the decision to sell I couldn't think of a better owner than Adam (Gladiator). It will be in a museum some day!! :001_smile:
