To restart a stopped Rolex Datejust 41, unscrew the crown and wind it clockwise before setting the time and date. Finish by securing the crown against the case. This guide focuses on the modern Datejust 41 references 126300 and 126334, with practical advice for owners who alternate between watches.

Check which Datejust you own

The Datejust name covers many generations. Start with the reference on your watch’s documentation rather than identifying it only by dial color. A blue dial or the slate Roman dial commonly called “Wimbledon” is a style choice, not a movement identifier.

Rolex’s specifications for the Datejust 41 reference 126300 and reference 126334 list calibre 3235: a self-winding mechanical movement with rapid date setting, stop-seconds and approximately 70 hours of power reserve. The winding routine does not depend on whether you choose an Oyster or Jubilee bracelet.

How to wind a stopped Datejust 41

1. Prepare the watch. Take it off your wrist and work over a clean, soft surface where you can comfortably hold the case.
2. Release the crown. Unscrew it completely. Leave it in the winding position without pulling it out to a setting notch.
3. Wind clockwise. Rolex recommends at least 25 turns for adequate partial winding after the watch has stopped. Turning the crown the other way does not wind it.
4. Set the display if needed. Use the crown positions below, then return the crown and carefully screw it down against the case.

The turn count comes from Rolex’s care instructions. “Partial winding” matters: it is a restart procedure, not a promise that 25 turns will provide the full advertised running time. Avoid judging the movement’s condition from that assumption.

Understand the crown positions

For initial setting, Rolex’s Datejust user guide gives this sequence: wind, establish midnight and set the time, then correct the date. In the time-setting position, advance the hands through 12; a date change identifies midnight. Continue to the correct time, accounting for morning or afternoon.

The first notch adjusts the date independently. Rolex’s family-wide manual notes that the direction varies by model; use the matching manufacturer demonstration or ask for a demonstration of your specific watch instead of copying instructions for another reference. After setting, return the crown inward and screw it down gently with light pressure. Never unscrew it underwater.

What approximately 70 hours means in everyday use

Seventy hours is two days and 22 hours. As an illustration, a fully wound watch removed at 8 p.m. Friday could run until roughly 6 p.m. Monday. That is an arithmetic example of the stated reserve, not a guarantee for an individual watch.

The practical question is how much energy was stored when you took it off. A watch that received only a partial wind starts with less reserve. Rolex explains that wrist movement powers the automatic winding system during wear. If you rotate watches, resetting one after it has run down can simply be part of your routine.

When to ask for help

If the crown feels gritty, will not engage normally, or requires unusual force, stop and have it examined. If the watch repeatedly stops despite winding and regular wear, record when it was wound, how it was worn and when it stopped. Those observations are more useful to a watchmaker than a guess about which internal part needs replacing.

For a used watch, also ask about service history and recent water-resistance testing. A factory specification does not establish the present sealing condition of an individual example. Our pre-owned Rolex condition guide provides a broader buying checklist.
