Datejust 36 TPD & Winder Settings | Swiss Watch Store

Datejust 36 — Winder Setting Overview

The Rolex Datejust 36 is an automatic watch, which means it winds itself from the motion of your wrist — but on the days it sits unworn, a watch winder keeps the mainspring topped up. The Datejust 36 runs on the Calibre 3235 calibre. Below you'll find the exact TPD setting and winding direction the Datejust 36 needs.

TPD and Winding Direction

The correct setting for the Datejust 36 is 650 turns per day, bidirectional: 650 turns per day with the rotor turning in both directions.

Why the Correct Setting Matters

The correct TPD mirrors what your wrist would do naturally across a normal day. It holds the mainspring at a healthy charge so the Datejust 36 runs at its best and is ready to wear at a moment's notice — exactly what a watch winder is for.

Don't worry if you're unsure — you can't break a modern automatic with the wrong winder setting; the slipping bridle on the mainspring makes overwinding impossible. The right setting just keeps everything running at its best.

Choosing a Watch Winder for the Datejust 36

For the Datejust 36, 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.
