Zenith Chronomaster Sport with El Primero 3600

Zenith enters the field of high-end sports chronographs with the launch of the cheap Zenith Chronomaster Sport. This watch incorporates the heritage of the manufacturer into a sports chronograph. To compete with Rolex, TAG Heuer and Omega, Zenith equipped it with a new movement capable of measuring down to a tenth of a second. Zenith also offers a date function and a sapphire crystal case back for its new timepieces.

Design based on previous model
The new model combines the details of the 1969 A386 with the shape of the Chronomaster De Luca. Also, other designs from the past are included. For example, the dotted bezel is inspired by the A277. Additionally, aspects of the Rainbow and Chronomaster Limited Anniversary Edition were incorporated into the final design of the new Chronomaster Sport.

Zenith Chronomaster Sport
The Zenith Chronomaster Sport comes in a 41mm stainless steel case. Its shape is inspired by the brand’s early chronographs. Hence, the sharply sloping lugs are from the A386. Also, the polished sides of the Chronomaster collection can be found here. Meanwhile, the black polished ceramic bezel has a 10-second scale instead of the usual tachymeter scale. cheap luxury watches

The dial is matte white or matt black, and the main hour hands and indexes are treated in black and coated with Super-LumiNova. The hands of the chronograph function have a red tip. Meanwhile, the applied sub-dials have the typical A386 colour code: light grey, dark grey, blue. The 60-minute counter at 6 o’clock and the 60-second counter at 3 o’clock both feature 60 graduations to provide an intuitive chronograph readout. Finally, the date is between 4 and 5 o’clock.

The new movement El Primero 3600
Inside the Zenith Chronomaster Sport is the El Primero 3600 movement, which is based on the El Primero 400 movement with some improvements. For example, it now implements a stop-second mechanism and the power reserve has been increased to 60 hours. In addition, the new structure of the movement now allows the wearer to better observe the working mechanism. For example, the blue column wheel is now no longer covered by the bridge, but lies freely on the 6-12 o’clock line. Also, the open rotor has a Zentraede star.

The frequency is maintained at 36,000 vibrations per hour (5 Hz), which allows the chronograph to measure down to tenths of a second. The chronograph now uses an improved horizontal clutch for power transmission. According to cheap Zenith, each individual wheel has a tooth profile that perfectly matches its function. The energy of the central chronograph hand no longer comes from the seconds wheel, but from the escapement itself. This allows a full rotation of the central hand in 10 seconds, divided into precisely 100 positions.

Chronomaster Sport Bracelet
Zenith has equipped the Chronomaster Sport with a brand new stainless steel bracelet. This features three links and has a wide, polished midsection. In addition, the bracelet has a folding clasp with a safety bar. In addition, the fine adjustment of the clasp allows the bracelet to adapt to the wearer.

In addition, a rubber strap is also available. The strap is blue for the white dial variant and black for the other. Textured rubber is similar to Cordura’s textured surface. Again, the strap is secured with a stainless steel folding clasp.

The Zenith Chronomaster Sport will be available at the end of January. In addition, a gold case variant for June 2021 is in development.
