Zenith Chronomaster El Primero Full Open
With this new model by Zenith, the El Primero movement reveals its skeleton.
To ensure a better understanding of the fundamentals governing its flagship Chronomaster collection, Zenith offers its legendary El Primero chronograph in three different versions: with an entirely solid (closed) dial, a half-open (Open) dial, and now an entirely open (Full Open) dial.

This complete opening enables clients to grasp and visually appreciate the high frequency of the movement, the signature of the legendary El Primero integrated automatic column-wheel chronograph calibre with its 326 components, beating at the swift pace of 36,000 VpH and offering a 50-hourpower reserve.
Three counters complete the picture: the 30-minute counter at 3 o’clock, the 12-hour counter at 6 o’clock, and the small seconds counter at 9 o’clock that notably serves to verify the smooth operation of the movement.
Available in 38mm and 42mm diameters, in steel or a two-tone version with steel topped by an 18K pink gold bezel, the watch is fitted with an alligator leather strap or a metal bracelet and is water resistant to 100 metres. Over 50-hour power reserve. Water-resistant to

While the mechanism is now entirely revealed, there are nonetheless a few subtle nods to the historical version of the El Primero 1969: the date window of the 38mm version has been placed between 4 and 5 o’clock just like the original; and the famous blue colour is identical to the historical version. Combined with the two other colours, anthracite and rhodium.
