The Zenith caliber Elite 670 SK is a skeletonized automatic movement with 27 jewels. This movement was introduced in 2018.

In Zenith’s own words:

“Beating inside its light titanium case is a Manufacture Zenith movement – the famous automatic Elite 670 base calibre. – reinterpreted in DEFY model. For the very first time, this reliable and accurate engine, fitted with a silicon pallet-lever escape-wheel, is revealed by means of an ultra-modern openworked approach. Blackened, structured and topped by a cut-out date disc read off on a white dot at 6:00, it oscillated at 4 Hz and enjoys over 50 hours of autonomy.” -Source: Zenith Defy Classic press-release

Zenith Elite 670 SK VS Elite 670:

The SK stands for “skeleton”, as this movement is the skeletonized version of the base caliber Elite 670. Other than the skeletonization, the two movements share the same specs.
