Hello guys again! I am Bruno!

Another project to be done a Junghans cal 687.

First sight, Crown has no groves (seems not to be the properly condition) it’s so plain that finger slips whe trying to winding.  
 

I have made a first seatch on cousinsuk and they don’t offer stem/crown for this.

I found on ranfft.de the model for stem wich is Stem W3144 / W2808.

at least, where can I find this or jow to start this

thannks

Osvaldo Bruno

Hello Bruno, I've recently got a Junghans working again. A 620. Mine was missing the stem and crown. Your best bet is likely ebay. That's where I got my new old stock stem from. The crown I salvaged from an old quartz watch. Fitted a treat. If your stem is serviceable you should be able to get crown fairly easily.

Do you have any pictures? Good luck

Hello Bearman!

the stem looks fine (picture not so good). It seems I can look for a crown and replace it if it doesn’t break in the process.

brunomartins,

I recently had a crown in similar condition and since the plating was long gone, I just re-knurled it.

I went about it very lightly because I didn't want to loose the rounded appearance and feel from the passage of time.

Hello Bruno,

wow that is smooth. It must be a well used and loved watch. Do you have a pin vice and a digital caliper? Armed with these you'll be able to remove the crown and measure for it's replacement. There's some good you tube videos describing this if you've not seem already.

Any luck with ebay?

      Hi,   My name is Simeon I am based in Sydney, Australia and have recently got into watch repair / watch making.  I am very much a learner having serviced multiple forgotten watches, some of which were actually successful!   I have a slowly growing collection of watches, mainly old Soviet, a few Japanese and (not pictured) some Raketas, a Poljot Alarm, an Omega Speedmaster Reduced and a vintage (1972) Tissot Seastar.  I like unloved vintage watches, with quirky faces and enjoy bringing them back to life through the simple(!) act of disassembly, clearing and reassembly. I am an Electrical Engineer who also undertook a trade apprenticeship so I am reasonably handy - It's fair to say, I know just enough to get myself in trouble.

      Seiko kinetic generator coil

      By DonEilenberger · Posted

      Sorry to reopen a necro-thread (long dormant) - I have a Seiko Kinetic 5M42A that needs at least one coil, possibly both. Anyone know of any sources?  The usual fallback of eBay has failed me - there are people selling coils, but not the ones for this movement (which was apparently a very popular movement, used in Seiko and Pulsa branded watches.) The coil numbers are: 4002 516,  and 4002 519 I'd also love to find a source for spares of the screws used all over this movement - they're Seiko PN 0022 247 Thanks! (Moderator - if this should be a new thread, please do feel free to tell me, or drag this one into a new thread.) Don Eilenberger

      I didn't take it apart until after you kindly explained its function! In fact mine doesn't work exactly the same way as described in the link OH provided in that it's not the whole block that moves but just the internal spring & its support. However, the 'franken-spring' I've cobbled together pending the right one turning up is, it seems, too thick to slip through the join in the two halves of the block as the mechanism is activated....
