Dear members, I came across a Ronda 5040.B quartz movement and the fact is I'm stumped as how to remove the stem. I tried the small hole marked with an arrow (in the movement, faintly, the one between the 2 screws by the stem) as in the picture but nothing gives underneath and nothing happens. I appreciate any information/trick/how-to/etc you can provide and thank you in advance.

Thank you Geo, Blacklab and haratua, I managed to have the stem out. It seems I was not pressing the lever hard enough. This is a never serviced watch that belongs to a friend. When the crystal broke he just put it away in a drawer so the parts inside (battery was out for a long time) didn't get to move at all. It needed a little coaxing to let the stem go! The position for the stem is all the way in, or at least that's the way it worked for me. Also, it took a .80 screwdriver tip firmly in. The former tiny, thin and plastic screwdriver I was using was inadequate. The stem was completely dry (no lube).

At first sorry for my english. I am a german guy. ;)

Here is the solution how the crown release mechanism of a Ronda movement works.

I have a Ronda 5030.d movement and struggeld with the same problem and didn`t find any answer in the net.

Just check the Ronda webpage (Ronda offical page). Search you type of movement. I think there is no big differences how it works.

Scroll a lil bit down and choose "technical Documents" and take a look in the "Casing information" PDF or/and download it.

In this PDF is listed in which position the release button works. :D

I also searched over 4h to find it... . But now I know that they have all informations online.

I hope my first post in this forum can help you guys. ;)

 

I know it is an older entry but may it could still helps some people.

Yes, CB it is there! It is an old post with my first Ronda of this design. The place you push (inside) is quite slippery (or I was too delicate with it) and if not done properly it won't work...or at least that's what happened to me in this instance. Thanks guys.

Cheers,

Bob

      Stem removal after fitting hands

      By PeterS · Posted

      Yes, the seconds hand is the longest and goes almost to the edge of the dial. I can’t quite picture it how you do it on the rubber pad

      A don't think so it leaked or damaged it because the watch itself works it just the buttons ain't working not connecting with the circuit board have taken more pictures of where the buttons makes contact with the circuit board.

      Stem removal after fitting hands

      I think what peter means oh is once he has fitted the hands and  checked for  alignment if them and that they dont foul, how does he then hold the movement to remove the stem in order to case up. The dial cannot be laid on a cushion or in a movement holder as the hands will get damaged. This can be quite tricky for a beginner, what i do is  to stand the movement on edge on a rubber pad so it doesn't slip. Hold the top edge with one finger then my dominant hand uses 3 fingers to press the stem release and flick out the stem. See below peter, leave off the second hand as this is the longest and gets caught the most, then fit it once the stem is out. Alternatively place the movement in one of the cup style holders, i imagine this is what they are designed for. They only touch the very edge of the dial.

      Yes I understand that. What I’m asking is, after the hands have been fitted, it’s been checked that the hands do not touch etc. then I need to remove the stem to fit the movement in the case. I have the push type, I need to turn it upside down and push the setting lever post and pull the stem out. But of course the dial and hands are in place and I have a glossy dial with lume dots and I do not want to cause any damage while it’s upside down pushing on the post of the setting lever.

      You have answered your own question. You just push the setting lever nipple in or if its the screw in type unscrew it a little. You should always remove any hands and the dial before putting it in your movement holder.
