Unable to manually change date on my Rolex Oyster

The Rolex time change is done after three clicks when you pull the winder. If the winder can actually be pulled out of the stem (separate) the damage is serious.
Sorry. Only an authorized dealer can get the parts for it to be repaired.

Howdy..

Not sure what your question is.. but I assume you wish to know if you have the real thing or not.
The watch you describe is a reproduction and not the genuine article.

I am sure there are other indicators.. however the Daytona and 99.9999% of all Rolex watches do not have engraving on the back cover.
Best of luck

Unscrew crown pullout 2 stepsturn hands around till the date changes .this will indicate to you it is midnight .turn ands around to right time.if you are setting this in the afternoon remember to go past the 12.When this is done push winder in 1 step and turn winder clockwise or anti cclocwise and this will let you set day or date. When you finish push winder back in and lock down.

You can get user instructions for their web site http://www.rolex.com/en#/rolex-watches .

Click on "collection" and then choose your watch from the list (incidentally, I couldn't find "daytona oyster" but "Daytona" and "Oyster"!).

At the bottom of the page you will find "downloads".

Click on this and then on "user guides".

AS I'm sure you know, when changing the time (presumably by pulling out the winder), the watch stops.

Normally the watch re-starts when the winder is returned to the "in" position.

Check that the winder is fully home.

If it doesn't start, pull the winder out and in again. If necessary try this several times.

If this does not solve the problem, then a visit to Rolex may be necessary!

Unscrew the crown and then pull the crown out to the second click and turn. When done push the crown back in and screw the crown back down.

It is very important to screw the crown back down. If this is not done the watch is NOT water resistant.

Hope this helps.

There isn;t any downloadable manuals for Rolex watches, but operation of Rolex Day-Date is very simple:
1) when you unscrew the crown, it is in winding position,
2) when you pull out the crown to the first click, it is in day and date setting position (depending wich way you turn the crown).
NOTE: to adjust the day or date, previously you have to advance hands forward, passing 12 o'clock (midnight) mark and stop advancing at 4.00 a.m. using the crown in position as described in chapter 3. When done - push the crown fully in, then pull out to the first click and only then adjust the day or date.
3) when you pull the crown further out to the second click, it is in time setting position.
To find the daytime or night time on the watch: pull out crown to the second click and advance watch hands forward till you pass the 12 mark on dial. If the date changes as you pass it - it is the night time (midnight). If the date do not change as you pass it - it is the daytime (noon).
After all settings being done, allways screw the crown back down as it protects the watch from water and moisture.
Never use watch in sauna- it's not designed for that.
Do not forget to rate, please.

There are two positions for the setting crown all the way out is to set time,one click out to set date.To set the date you must first set the time by moving the hands around clockwise until you see the date change(midnight) then continue around to the correct time.Then push crown in on click and set the date
