New Timepieces from Zenith

Zenith unveils the revamped Chronomaster Open line as well as new Chronomaster Sport during Watches & Wonders 2022

Watchmaker Zenith has unveiled the revamped Chronomaster Open line as well as new Chronomaster Sport under its new ‘Master of Chronographs Since 1865’ platform.

Zenith is well-known for its chronographs. With many world-firsts and record-breaking feats to its name, including with the El Primero chronograph and its numerous evolutions.

Unveiled at Watches & Wonders, the Chronomaster Sport received a great reception for its 1/10th of a second chronograph, whilst the team also announced the expansion of the line this year to include a rose gold version. 

Zenith also brought back a modern Zenith icon from the last twenty years: the Chronomaster Open. Originally launched in 2003 as the first chronograph with a partially open dial to reveal the regulating organ and escapement, the Chronomaster Open returns in a totally redesigned form – inside and out.

Crafted in a more moderate 39.5mm case in steel or rose gold, the new Chronomaster Open revisits the iconic tri-colour dial configuration with a transparent twist. Instead of cutting out the small seconds counter at 9 o’clock entirely as was the case previously, the three counter colours are kept thanks to a hesalite crystal element that serves as a readable sub-dial while allowing a view of the silicon star-shaped escape wheel. 

The opening itself has also been reinterpreted, foregoing the former version’s applied “frame” and instead opting for circular openings with chamfered edges, revealing the movement with more straight bridges and a more contemporary grey tone.

Powered by the El Primero 3604 calibre, the newly developed movement is based on the El Primero 3600 1/10th of a second automatic high-frequency calibre, with a more open architecture.
