A superb vintage from the late 1910s with an unconventional shape, and probably the only watch on the market in such a configuration and condition! This superb Longines comes with an unusual "Baignoire" case, manufactured in 14-carat gold in the '10s. Rare enough to be noted, its radium dial is entirely original with large "Bréguet" numerals and has never been restored, just like the 11.62N movement that powers it and the rest of the watch, which has stood the test of time superbly well. This extremely rare reference 613 is a genuine museum piece, and comes with its box and an archive extract dating from the watch's first sale in August 1919. A very contemporary and unisex watch in terms of size and case shape, a must-see.
