Day-Date 36 TPD & Winder Settings | Swiss Watch Store

Day-Date 36 — Winder Setting Overview

A Rolex Day-Date 36 (reference 128239) deserves the right care between wears. That means a watch winder programmed to its exact turns-per-day requirement and winding direction. The Day-Date 36 runs on the Calibre 3255 calibre. Here's the correct configuration for the Day-Date 36.

TPD and Winding Direction

TPD: 650 turns per day. Winding direction: bidirectional. Set your winder to 650 turns per day with the rotor turning both ways, and your Day-Date 36 will stay perfectly wound.

Why the Correct Setting Matters

Accuracy starts with a fully wound mainspring. The correct TPD keeps your Day-Date 36's power reserve topped up around the clock, so the movement delivers its best rate and the watch is always ready to wear.

One reassurance: if the setting is slightly off, a modern automatic won't be harmed — the slipping mainspring bridle prevents overwinding. Accuracy and readiness are the reasons to get it right, not safety.

Choosing a Watch Winder for the Day-Date 36

Pair the Day-Date 36 with a quality programmable winder set to its 650 TPD / bidirectional programme. A single-watch winder is ideal if this is your only automatic; if you rotate several watches, a multi-watch winder is the smarter buy.
