Lady-Datejust 28 TPD & Winder Settings | Swiss Watch Store

Left unworn, the Rolex Lady-Datejust 28 will run down within a couple of days — a correctly set watch winder stops that happening. This model carries reference 279174. It is powered by the Calibre 2236 movement. Here is the TPD and direction this model calls for.

TPD and Winding Direction

The correct setting for the Lady-Datejust 28 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	Calibre 2236

Why the Correct Setting Matters

An automatic watch is only as accurate as its power reserve allows. Keep the mainspring properly tensioned and the Lady-Datejust 28 will hold its rate and be ready to wear the instant you pick it up — no resetting the time and date. Set the TPD too low and the watch can run down between wears. The movement will not be damaged (modern automatics have a slipping mainspring that prevents overwinding), but an under-wound watch is simply not doing its job. Correct settings are about accuracy and readiness, not safety.

Choosing a Watch Winder for the Lady-Datejust 28

For the Lady-Datejust 28, 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.
