The Longines caliber L888 is 3-hand automatic watch movement based on the ETA caliber A31.L11. It is a Swiss made with 21 jewels, produced by ETA (Swatch Group).

Longines L888 Variations:

There are other versions of the calibre L888 listed below.

  • L888 – Not COSC
  • L888 ND (No Date) – Not COSC
  • L888.2 –
  • L888.3 –
  • L888.4 – Silicon balance spring, COSC
  • L888.4 ND – Silicon balance spring; COSC
  • L888.5 – Silicon balance spring; not COSC

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 (L3.784.4.56.9) 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.

So far just picked up the Hydro Con. 39mm Cermaic with silicon spring and the watch works like a tank. Nov. 2022 no issue or regrets. Best value out there for size, Power Reserve, 5-year warranty, and overall feel, ordered with the Rubber strap for winter use and have a Horus for summer (thinner and more breathable).
