Notes
The 8.68Z is a continuation of the project started with the 12.68Z to standardize and rationalize production across the range of Longines movements, so that the company could more easily and cost effectively produce a larger number of movements. The 8.68Z was in effect just a smaller version of the 12.68Z, itself a smaller version of the 18.68Z. It was designed for small and women's sized wristwatches. Also referred to as the 8L usually in the American market. The 8.68N is an incremental refining of production techniques that happened in 1937, it also changed the bridge structure to be more in line with the other modernized calibres.
