Longines - Lindburgh Hour Angle


Product Details

One of the most inexplicable of timepieces ever devised. A watch that not only tells you the time but can also be used (in association with an astronomical almanac) to determine your latitude and longitude location anywhere on Earth. Though it definitely requires more than a little bit of practise and study to learn how to use that feature.

Watch is is good condition with signs of wear but otherwise in fine order. Comes with full kit, box, papers and additional strap part which is used to extend the strap already on the watch (the watch is intended to be worn over a flight jacket). Also comes with an annotated map of Charles Lindburgh's travels, and a history book from Longines. Also an instruction manual ... though if you intend to use the location features of the watch, we can recommend a couple of youtube videos which explain its functions much better.

Not a fan of irregular lug width sizes? .. this watch says "Bite me! It's 25mm, deal with it!"

A watch that requires a study of 'The Equation of Time'. You don't have to have a PhD in nuclear physics to use this watch .... but it might help! It does, at least, tell you the time easily enough. A unique, fun and extremely interesting time piece. Elegant, different and a fascinating piece of horology.

Comes with a 2 year warranty from us.
