Chronomaster Sport TPD & Winder Settings | Swiss Watch Store

The Zenith Chronomaster Sport is an automatic watch: it winds itself from the motion of your wrist, but on the days it sits unworn a watch winder keeps the mainspring topped up. This model carries reference 03.3100.3600. It is powered by the El Primero 3600 movement. Below you'll find the exact TPD setting and winding direction the Chronomaster Sport needs.

TPD and Winding Direction

The correct setting for the Chronomaster Sport is 650 turns per day, bidirectional: 650 turns per day with the rotor turning in both directions.

Turns per day (TPD)	650
Rotation direction	Bidirectional
Movement	El Primero 3600

Why the Correct Setting Matters

Too few turns and the Chronomaster Sport stops between wears; the right figure keeps the mainspring in its sweet spot, where the movement runs most consistently. And there is no risk in experimenting: a modern automatic cannot be overwound on a winder, because the mainspring's slipping bridle releases excess tension. Getting the setting right is about convenience and accuracy, never about avoiding damage.

Choosing a Watch Winder for the Chronomaster Sport

For the Chronomaster Sport, look for a programmable winder offering a 650 TPD bidirectional programme. One watch? A single winder. Two or more automatics? A double or triple winder keeps the whole rotation ready. You'll find suitable models in our watch winder collection — check the programme list before you buy.
