IN-DEPTH: The Lineage of the Longines Czech Aviator Chronometre

The so-called "Tartarugone" is a chronometer wristwatch that was produced by Longines for Czech aviators before, during, and after the Second World War. The Tartarugone features a unique case shape and has greatly evolved over time—utilizing three different movements. The second series, which was made in a very limited quantity, is seldom seen in good condition. While the other variations are not as rare, they are a financially-accessible alternative to the higher-priced Longines pilot's watches of the early 20th Century. Let's take an in-depth look at the history of this fascinating wristwatch.
