Hello all,

I have a seiko 5m42-0a19 kinetic watch which I dearly love. One day at work I somehow twisted or bent the crown, which promptly snapped off. With the magic of the internet, I managed to figure out how to take the stem out of the works. Now I have a stem with some threads on the outside of it with the remains of the crown still screwed into it.

I am needing the necessary stem and crown to make this watch complete - can someone tell me what the part numbers are, and where can I purchase them? This is my first foray in to watch repair, and I hope I can save this one. I think I will also need a gasket (?) to seal the back cover when I put it all together.

Just a question - why can't everyone make sapphire crystals? I haven't been able to scratch this one yet, and I really abuse my watches. I also have a seiko automatic with a hardlex crystal in which you can almost make out what time it is...... is there a way to buff or sand out the scratches? Or is it lost?

Thanks for your help.

Can you remove the piece of broken stem from the crown?

Your crystal may be salvageable. If you work with an 800 grit wet/dry sand paper followed with a 1200 wet/dry sand paper then finally finishing with brasso or Solvo Autosol, you can probably restore it to near new visibility. It could take several hours of hand polishing to achieve this though. A new crystal may be more appropriate unless you have the patience to do the polishing yourself.

Ok - maybe I'm not using the correct terms - I'm including a picture of what is broken - the right side is what would be on the outside of the watch, except it is broken. It has threads, but I don't want to attempt trying to take it off - I would really ding up the threads on it, I'm afraid.

The stem looks fine. The piece that is screwed on the right end of it is part of the crown.
So, all you need to do is unscrew that piece and buy a new crown :-!

Great!! Now, where can I find one? Ebay, or somewhere else??

Thanks for your help - it is appreciated.

I had to get my parts from donors...eBray is a good place to start. In particular; look at 'thewatchcollector' auctions. He often has 5m42 and 5m43 parts watches.

Just an update - I found a donor watch from the watch collector and will expect it in the next week. It has a good stem and crown - hopefully I can just do a swap and have my watch back!!

I also need some guidance as to the gasket in the back - can I use some silicone instead of a gasket, or try to re-use the one that is there? It's not broken..... Just wondering what other do. If I have to get a new gasket, where should I look?

Thanks again for the advice - looks like it's paying off already!!

If the gasket is not broken then use a little silicon grease or olive oil will do in a pinch.
Don't use Silicone Sealer anywhere around a watch; it can be corrosive or harmful to the movement. It can also leave a greasy film on the inside of the crystal.

If you need a new gasket, just place a WTB on one of the trade forums and I'm sure you'll find one quickly...they aren't expensive either.
