Hi all. Can anyone kindly advise the best process to remove the whole 3285 movement from the case? (Rolex explorer II) ie the crown removal and if any screws hold the movement in after that?
Thank you
Thank you

Your movement is an ETA clone 2836 if your GMT hand is on the bottom of the hand stack or an ETA clone 2824 if the hour hand is in the bottom.
Put the stem in the time setting position for stem removal and press the stem release button at A to release it. Be gentle and press no harder than necessary while pulling outward on the crown.
Turn the two screws at B clockwise to lower them to the movement. They have been unscrewed (raised up) so the head ledge can anchor under the case lip. Normally with this method there is a cutout in the lip around 9 or 10 o'clock and you rotate the whole movement plus movement holder anti-clockwise to free them from the case.
Your pic is cut off so I can't see this but because the top B screw has one straight cut edge, I think when you screw that one down the cut edge will be under the lip which will allow the movement plus holder to be lifted up. However the bottom B screw does not appear to have a straight cut edge so it looks like you will still have to rotate anti-clockwise so the bottom B screw head aligns with the case lip cutout at the stem location.
The screws and tabs at C hold the movement to the movement holder. You should not have to touch those at all. In fact I would not, as they assure rotational alignment between the dial and the movement. The dial feet are attached to the movement holder so if you alter this alignment it will change your hands position relative to the dial and your date window position relative to the datewheel.

Superb thank you very much. Movement removed successfully and 9oclock marker repaired. All back and workingYour movement is an ETA clone 2836 if your GMT hand is on the bottom of the hand stack or an ETA clone 2824 if the hour hand is in the bottom.
