The history of the Rolex Daytona and its incredible success hinges massively on the technological breakthrough Zenith made with their El Primero.įor anyone in the dark, when Rolex launched their first production chronograph in 1963 it was the closest that giant of a brand had come to experiencing out-and-out failure. White dial: Stainless steel bracelet with double folding clasp or blue rubber strap with Cordura effect.For this edition of our ‘Rivalry’ series, we take a look at two watches that manage to be fierce competitors while also sharing a vital bond in each others narratives. The price for the two models with rubber straps is 9,200 euros. Furthermore, a variant with a gold case is in the works for June 2021. The Zenith Chronomaster Sport will be available from the end of January. Again, the strap secures using a stainless-steel folding clasp. The textured rubber resembles Cordura with its textured surface. This strap is blue for the variant with a white dial, while it is black on the other. In addition, a rubber strap is also available. Furthermore, the clasp’s fine adjustment allows the bracelet to adapt to fit the wearer.

In addition, the bracelet has a folding clasp with a safety bar. This has three links, and features polished wide middle parts. Zenith equips the Chronomaster Sport with a new stainless-steel bracelet. This allows for an entire rotation of the central hand in 10 seconds, divided into exactly 100 positions. The energy for the central chronograph hand no longer comes from the seconds wheel, but from the escapement itself. According to Zenith, each individual wheel has a tooth profile perfectly matched to its function. The chronograph now uses a revised horizontal clutch for power transmission. The frequency remains at 36,000 vibrations per hour (5 Hz), which allows the chronograph to measure to a tenth of a second. Moreover, the open rotor bears the Zenith star. For example, the blue column wheel is now no longer covered by a bridge, but lies freely on the 6-12 o’clock line. In addition, the new structure of the movement now allows the wearer to have a better view of the mechanism at work. For example, it now implements a stop-seconds mechanism and the power reserve has increased to 60 hours. Inside the Zenith Chronomaster Sport is the El Primero 3600 calibre, which uses the El Primero 400 calibre as its base, while offering some improvements. Finally, the date is located between 4 and 5 o’clock. The 60-minute counter at 6 o’clock, as well as the 60-second counter at 3 o’clock, have a 60 scale to provide an intuitive reading of the chronograph. Meanwhile, the applied subdial counters are in the typical A386 colour code: Light Gray, Dark Gray, Blue. The hands for the chronograph function bear red tips. The dial is either matte white or matte black, while the hands for the main time – as well as the indices – are blackened and coated with Super-LumiNova. Meanwhile, the black polished ceramic bezel has a 10-second scale instead of the usual tachymeter scale. Furthermore, the polished flanks of the Chronomaster collection can be found here as well. Accordingly, the sharply sloping lugs come from the A386. Its shape is inspired by earlier chronographs of the brand. The Zenith Chronomaster Sport has a 41 mm case made of stainless steel. In addition, aspects of the Rainbow and the Chronomaster Limited Anniversary Edition have also been incorporated into the final design of the new Chronomaster Sport. For example, the bezel with dot markers is inspired by the A277. Furthermore, other designs from the past have also been included. The new model combines details from the A386 from 1969 with the shape of the Chronomaster De Luca.
EL PRIMERO SPORT PLUS
Zenith is also giving its new timepiece a date function plus a sapphire crystal caseback. In its bid to compete against Rolex, TAG Heuer, and OMEGA, Zenith is equipping it with its new calibre, capable of measuring to a tenth of a second. The watch packages the manufacture’s heritage into a sporty chronograph. Zenith is venturing into the contested field of high-end sports chronographs with the introduction of the Zenith Chronomaster Sport.
