Editor’s note: Longines does not make it easy. Researching the differences between the various L888 calibers is its own kind of hell. There is minimal consistency. For example, on the black ceramic Hydroconquest (L3.7188.8.131.52) press-release, Swatch Group makes a brief mention of the caliber L888.3 inside. Then, on the official product page, it is simply referenced as L888. Will update these pages with more info later.
