The Zenith Chronomaster Open made its debut back in 2003. With the partially open-worked dial, the watch offered a glimpse of the El Primero movement within. It was an instant hit. Now, Zenith revisits the concept with the introduction of brand new 2022 take on the Chronomaster Open!
The 2022 Zenith Chronomaster Open features a case of 39.5mm. The dials feature the well-known tricolor sub dials, but now with the signature cut-out at between roughly 8:00 and 11:00. The look may be familiar, but the case is completely redesigned - sleeker, with slimmer lugs and more pronounced bevels. And the movement within? That too is entirely new. Beating away inside is the El Primero 3604. Being a modified version of the El Primero 3600, this of course features the amazing 1/10th of a second chronograph.
