Catalogue Essay
- A duo released in 2021, the Zenith Chronomaster Sport chronograph featuring ceramic bezel with black or white dial is the modern version of the Striking Tenth which first patented circa 2002 with the introduction of the calibre 4052.
- Fitted with the newly upgraded high beat El Primero calibre 3600 and beating at 5Hz, the chronograph measures time down to 1/10th of a second prompted by a pump pusher, it also features hacking seconds, quick-set date and has an upgraded power reserve of 60 hours of action.
- Aesthetically pleasing with blued screws and a large blued steel column-wheel, the wearer can admire the calibre 3600 with unobstructed view thanks to the skeletonized star shaped Zenith Rotor.
- Sized at 41mm and cased in stainless steel, the Zenith Chronomaster Sport features a tri-color dial that differentiates its overlapping registers clearly: 60-second, 60 minute and small seconds. The Zenith star logos can be spotted both on the chronograph counterbalance as well as the applied logo at 12 o’clock which is a nice sporty touch to the overall timepiece.
- Preserved in excellent overall condition and complete with its warranty and accessories, the Zenith Chronomaster Sport is a robust and a joy to operate and wear.
Since Zenith's beginnings, founder George Favre-Jacot sought to manufacture precision timepieces, realizing quality control was best maintained when production was housed under one roof. Zenith remains one of the few Swiss manufacturers to produce their own in-house movements to this day.
Today, the brand is best known for the "El Primero," the firm's most successful automatic chronograph movement. In an interesting twist of fate, the company that owned Zenith during the 1970s decided to move on to quartz movements and therefore sought to destroy the parts and tools necessary to make mechanical movements. One watchmaker realized this folly and hid the tools and parts before they were destroyed. In 1984, he returned them to Zenith so they could once again make the El Primero movement.
