Help finding a Michael Kors watch crown.

[cfauvel]

Watch Michael Kors MK2521 woman's watch 

Ok so I did a newbie mistake and used the wrong die in my case back press. The die was too large which allowed the crown to rest on the edge when I pressed down on the press it snapped the case back on as well as snapping the stem right at the base of the crown.

The quartz movement is a Miyota 9T33 and found that the stem is a Miyota / CITIZEN Watch Stem 65-495. What I can't seem to find is a Michael Kors crown. I know I could put on a different gold tone crown, but would like to put a real Michael Kors crown back on.

 

Maybe you all have an idea on how to get the broken threaded piece out of the crown..I personally don't see that being possible as there is nothing to grab on to.

The diameter is 4.48 MM, the total depth is 5.45mm (if that makes a difference), The outer barrel (silver part) is 1.83MM. The inner barrel (where the stem screws into) is 1.27MM

Thanks in advance

Micro screw extractor.  Drill a hole in the stem to the correct size for the extractor.  The extractor has a left hand thread that grips in the hole.  Google it.

I'm having a hard time finding anything that is a smaller diameter than 1.2MM, I believe the stem is like .9MM

Your profile doesn't state where you are from.  This is from cousins uk, ebay also have them and other materials houses should have them too.  The extractors are sold separately from the tool.

Thanks a lot...I'll change my profile to reflect that I am in Sarasota, Florida USA.

I'll search for some videos on how to use that ...I am having  a hard time envisioning how a watch movement is secured in that thing let alone a crown.

[RichardHarris123]

The extractors are secured in the clamp and the movement is turned.  You would secure the extractor and move the crown. A video will help.

I saw a video where someone removed the broken stem from the crown by soaking it in a mixture of water and alum powder.  It seemed to work.  Where can I find a stem for a Michael Kors MK-5725 watch?

Welcome to the forum.

Yes, alum powder does work to dissolve a stem but it's best kept warm to speed up the process.

You need to remove the back from the watch and see what movement it has.

There should be markings but if you can post photo along with
where in the world you are to point you in the right direction.

Edit

A photo of the crown & broken stem would also help to see if it does need dissolving.

I don't think you'd get a grip on a stem with these.

Two things with an using alum solution to dissolve the stem. 1 ( obvious ) check that the crown has no steel components ie .  The crown itself ( possibly ) the threaded crown tube ( probably) the crown washer ( almost certainly ). I'm also under the assumption that stainless steel stems are unaffected by alum ?

If trying the extraction method, help that situation by softening any adhesive between the broken stem and the crown tube. Some radiated heat  ( not direct flame ) an adhesive softener, acetone.

Are the crown components SS ? SS is usually non magnetic  having nickle as an additional element besides chromium.

To source a new stem, you need to identify the movement in the watch. 

If I recall correctly, the MK-5725 uses a Hattori SII VD53B movement or a close relative thereof. 

The movement will have enough information on it to verify what model it is. 

Hope that helps,
