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

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.

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.

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,

Mark

    • Hello Tom and welcome to the forum.
    • Hah! Well, California will have to do. Lived in TX for a brief period back in the early 70s, though, so maybe that counts. 🙂 Funny you should mention making vacuum tubes- I've actually tinkered with that! It's REALLY tough to do, and I've never made one more complicated than a simple diode that barely worked, but I have played around at it. But there's just no infrastructure for vacuum tube fabrication. I can get a lathe and learn how to use it to make complex parts, and while it might take a while to learn- and money to get the equipment, of course- it is possible to do more or less "off the shelf". But vacuum tubes, not so much. There are a few folks out there doing some crazy cool work with bespoke tubes, but they have setups that are far beyond what I can manage in my environment and it's mostly stuff they built by hand. I also have been playing with making piezoelectric Rochelle Salt crystals to replace ancient vacuum tube turntable needles- nobody's made those commercially for probably 60 years. I'm a sucker for learning how to do weird things no one does any more so I can make things no one uses work again. (I think this is drifting off the topic of lathes, lol).
    • You shoulda been born in Texas. Tough to make a vacuum tube though. You can substitute with a MOSFET eq ckt I guess. I was playing around making a pinion the other day. More to it than meets the eye.
    • Well, turns out it was a fake bezel! The crystal is domed mineral glass and I was able to find a cheap replacement that should be here in two days.  I used my crappy little press to pop out the cracked crystal, Ill give the case a good cleaning in the meantime and do a once over on the movement.
