[Solved] Ingersoll watch stem removal.

The back case 

The dial

Hi Jas, it looks like you have an Ingersoll Dream watch with Ingersoll caliber IN 420 (will get this and its base movement listed soon). There is a stem release/detent button circled in the picture below. Hope this helps, please report back.

Hi

I tried to push the dimple and at the same time pull out the crown but the dimple will slide inwards and wouldn't release the stem. See picture with red arrow where the dimple will slide in. 

This is the photo with the crown in the winding position 

This is the photo of the crown in time adjusting position.

Hi Jas, I found a watch with a similar movement.

The detent button (dimple) is meant to appear in winding mode and disappear in time setting mode, to avoid any issues that could arise from releasing the stem in the incorrect position (if only ETA incorporated this type of design in the 2824, it would have saved a lot of people headaches from messing up the keyless works).

Here is another close-up shot for anyone new to this thread.

You have to be gentle, yet firm when pressing the detent button down. If the detent is sliding inwards, it usually means there isn't enough pressure to lift the lever away from the stem.

Here is a picture of putting downward pressure on the button with tweezers. For this particular example, it required pressing a bit harder than expected to get it to budge.

Hi, 

I was afraid I'd damage the mechanism  if I apply more pressure. I will update again. Thanks for the tips.
