Zenith El Primero Chronomaster Open Heart Chronograph Power Reserve ref. 03.2080.4021/21.M2040 – Mint

During the 1960s, four major brands got into intense competition over creating the first-ever self-winding chronograph wristwatch. Heuer and Breitling collaborated and received the support of Hamilton, Buren, and Dubois-Depraz, while Zenith and Seiko chose to fly solo. By early 1969, all four companies had constructed a chronograph wristwatch that featured automatic winding, and they had all done it in a rather spectacular manner. The Caliber 11 from Heuer, the 6139 from Seiko, and Zenith’s El Primero all proved themselves accurate and reliable, impressively-engineered movements, each of which would go on to inspire a diverse line-up of respective successors.

The Zenith Chronomaster Open Heart Chronograph is one of such and is truly a stunning piece that combines the brand’s rich history with modern technology. The watch features a 42 mm steel case with a sapphire crystal caseback that allows you to see the intricate workings of the El Primero caliber 4021 automatic movement.
The dial of the watch is a beautiful matt black finish wit and luminous hands and markers, making it easy to read in any lighting conditions. The chronograph function is controlled by pushers located on either side of the crown, and the open-heart design at 10 o’clock adds a touch of elegance to the watch.
One of the standout features of the Zenith Chronomaster Chronograph is its accuracy, thanks to the high-frequency El Primero movement that beats at 36000 vph and offers a power reserve of 50 hours.
Overall, the Chronomaster 03.2080.4021 is a beautifully crafted timepieces that is both stylish and functional. It’s perfect for watch enthusiasts who appreciate the history and craftsmanship of the Zenith brand.
