⌚⌚⌚ HOTZenith Chronomaster Sport
El Primero high-frequency chronograph. The Daytona alternative.
Our take on the Zenith Chronomaster Sport
El Primero was among the first automatic chronograph movements in 1969 and remains one of the few beating at 5Hz, which lets it measure to 1/10th of a second. The tri-colour overlapping subdials are one of the most recognisable dial layouts in watchmaking.
What to know before buying
- ▸High-frequency 5Hz movement — 1/10th second chronograph resolution.
- ▸Tri-colour overlapping subdials in the A386 tradition.
- ▸Column wheel chronograph with vertical clutch on current calibres.
- ▸Roughly 60-hour power reserve on the modern 3600 series.
Where and how to buy
Zenith is chronically undervalued relative to its movement engineering, and authorized dealers are often willing to negotiate. Pre-owned El Primeros are one of the better value propositions in Swiss chronographs.

Zenith Chronomaster Sport — frequently asked questions
What does the high frequency actually do?
It increases timing resolution to 1/10th of a second and generally improves rate stability, at the cost of a shorter service interval.
Is El Primero serviceable locally?
It requires a Zenith-trained watchmaker for full service, so factor turnaround time in.
