ZENITH EL PRIMERO Chronograph T opens power reserve

Thierry Nataf’s time in “Zenith Watches” was controversial, but time proved one of his iconic innovations: the open escapement. This Zenith Chronomaster T Open Power Reserve is the intersection of Zenith’s traditional style and Nataf’s gorgeous charm.

The Chronomaster Open is not only a leader in the Nataf era, but also a place in the Pantheon (Zenith El Primero References).

In 1969, El Primero became the first high-frequency (36,000 VpH) automatic chronograph movement. Since then, it has been the darling of watch lovers and watchmakers. Zenith’s Chronomaster became the flagship of the El Primero series in the 1990s. This era provided the Chronomaster T with a 40mm stepped case.

The style of the case is Zenith in the late 1990s: restrained and classic. The dial is the same…until the escapement is considered. Then the fireworks started. Nataf learned that the romance of mechanical watches is closely related to the beating heart of beasts: the escapement. In the high-tempo El Primero movement, this fact is doubled. Even the naked eye can tell the difference between the legendary Zenith and the traditional 28800 VpH main horse of Rolex or ETA.

The open escapement is an excellent theater, and the El Primero calibre 4021, which is partly hollowed out, was developed to give a clear view of the famous high beating device. The spare balance wheel and the pallet rack hardly cover the mechanism, and the crazy parts are easier to see through the dial than the case back.

As long as you don’t talk about history or engineering, you can see this movement at a glance, which will win the hearts of casual observers and admirers. Chronomaster T Open Power Reserve has this appeal.

The backup fuel gauge at 6 o’clock brings you more complexity and convenience. The beautiful arc of the indicator tracks the energy stored in El Primero’s adequate 52-hour power reserve.

The 2000s was a transitional era in the history of Zenith buy replica watches. Some products are very successful, some products are not successful, but few products join the ranks of long history. From Audemars Piguet to Gruebel Foresey’s simulators, the Zenith open-air escapement set off a fire that has been burning to this day.
