Most horology aficionados are familiar with the legendary “El Primero” caliber movement, those who aren’t might not be as passionate as they like to believe.

With the addition of this new model to the line, it’s now possible to obtain a “Zenith El Primero Chronograph” in three distinct dials designs: completely closed, half-open, or now completely open! A trifecta chronicling the progression towards opening up and displaying this historic movement in full.

The case for these watches can be had in either a 38 or 42mm size, made out of either stainless-steel or a two-tone version with the steel topped by an 18k rose gold bezel. Despite its skeletonized dial the case back is also transparent, in order to further observe the intricacies of this mechanical movement, with its oscillating weight adorned with a “Côtes de Genève” pattern and other moving parts.

There are two push-pieces on the right-side of the case to operate the chronograph functions, with a crown in between them. The crown also features the classic embossed star logo on the top of it and a thin line was added to the heads of the piston style pushers. Overall the 38mm version may be closer to the original model it’s based on since they share the same diameter, but the 42mm has been crafted proportionately, so it all comes down to a question of personal taste or wrist size. Water-resistance on this watch can reach up to 100 meters (330 feet).

Time is exhibited in this see-thru, aforementioned fully skeletonized dial with either: stainless-steel or 18k rose gold hour index markers, depending on the model opted for, accompanied by smaller minute index markers. Yet followed by even smaller minute index markers with Arabic numerals for every five-minute increment.  There are three sub-dials: a 30-minute counter at the 3 o’clock position; a 12-hour counter at the 6 o’clock position; and a sub-seconds at the 9 o’clock position. The hands and hour index markers have all undergone a luminescent coating, for an enhanced legibility. There is also a date aperture at the 6 o’clock position.
