Datejust 31 — Winder Setting Overview

If you own a Rolex Datejust 31 (reference 278274), the TPD figure below tells your watch winder exactly how to look after it. The Datejust 31 runs on the Calibre 2236 calibre. Here's everything you need to programme your winder correctly.

TPD and Winding Direction

Programme your winder to 650 turns per day and select bidirectional rotation. These are the exact figures the Datejust 31 is designed to wind at.

Why the Correct Setting Matters

Get the setting right and your watch stays in its happy zone: a full power reserve, consistent amplitude, and the time you set last week still correct. Too few turns and the watch runs down; far too many and you're simply wasting the winder's energy.

Worth knowing: an incorrect TPD won't damage a modern automatic movement, because the slipping mainspring simply can't be overwound. Getting the figure right is about keeping the watch accurate and ready, not about protecting it.

Choosing a Watch Winder for the Datejust 31

Choose a winder with a proper programmable movement — one where TPD and direction are set independently, not a fixed-cycle unit. A single winder covers one watch beautifully; a multi-watch winder covers a growing collection. See our watch winder collection for options that support the Datejust 31's 650 TPD bidirectional setting.

Datejust 31 Winder FAQs

How many turns per day does the Datejust 31 need?

Use 650 turns per day — that's the winding rate specified for the Datejust 31, and it keeps the power reserve topped up around the clock.

What winding direction does the Datejust 31 need?

Bidirectional rotation is correct for the Datejust 31. Avoid clockwise-only or anticlockwise-only programmes, which would only do half the job.

Will any automatic watch winder work?

Any programmable automatic watch winder with a 650 TPD bidirectional programme will work. Steer clear of fixed-cycle winders that can't be set to the right figures.
