Ronda 5040.b Stem Removal Help

[bobm12]

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.

Try moving the stem to the out or in and a lever may appear in the hole. If it does press down on it to release the stem.

I'll try that again, thank Geo, maybe I'm not pushing with the right tool (too thin?).

Just had a look on the spec sheet on Cousins website, I agree with Geo's solution.

Some stems need to be in out position before you can press to release it. If it has multiple positions, try each.

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.

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.

Here is a pic of another Ronda I guess the stem removal is in the same area i.e. the hole.

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
