The movement inside remains the El Primero 400 Automatic, a classic iteration that falls very close to the original El Primero caliber – mind you, it is now behind a grey tinted crystal that makes it a bit more difficult to appreciate under some lighting conditions.


Both the front and back feature sapphire crystal windows, with the front featuring dual-side AR-coating over its boxed and slightly domed crystal element. The Zenith Chronomaster El Primero Full Open 38.00 comes in a 38mm wide and 12.45mm thick case, sporting an ample 100m of water resistance and matched to an odd, 19mm wide strap.
