Hi all - I have a Fortis Fleiger on the bench and the crown, which looks to have been replaced once already, has worn out. I beleive these crowns are supposed to wobble some by design. Are there measurements I can take to find a replacement? It is also a screw down crown. 41dbaf084aed2011c9a059360eff4e17.jpg

Thanks much for the info thus far, I havent replaced a crown of this type before so the picture is getting a little clearer. It does seem like parts are missing. Are the tubes pressed in?

How does the tube in the watch look like? I wonder as i can't see any gasket in the crown. Internal or external thread on the tube in the watch.

Looks to be external thread on both diameters of the tube, with an internal gasket. The crown contains a face seal gasket. I've attached some more photos. Needs a good scrub.576b5626d058f1f0347024eb3888a0e8.jpge05faf6b85eeddb6dd6914222e482506.jpgb78eb05a09743a913e3c4aeed49df49e.jpg8dc4245daac665fd7701e9f4e0fcb0fb.jpg

Looks a bit like a Rolex crown. Could be easy to find or  could be tricky. 

Or the best maybe would be to contact Fortis and see if the could help you out?

Is this what you look for?  Sorry for linking to Ebay . But was difficult to show in other ways. 
I think thats the correct set (internal thread for crown) and what I have is a replacement, perhaps a generic Rolex. I ordered some aftermarket parts for this movement. If they dont fit, will have to spring for the $70 factory parts. Thanks for keep an eye out, I'll follow up when parts arrive.

Hi, juat wanted to post an update that I got the aftermarket Rolex style crown in and it works well. I had to tap the case for the new tube and locktite it in place and make some adjustments to the stem and all is well. Thanks!

Most of the way through reassembly and I have mysteriously lost part number 161 the center tube...Are these easily sourced for a 2824? I found several on the Bay and one is titled 2800. Does that mean it fits all movements with a 2800 series prefix? I'm new to this taxonomy.

Best,

C

Its like a guide tube for the main wheel and is usually lightly pressed into the center of the main plate. I did, however, manage to find it!9631463a3376a003c5171007329d4e23.jpg

 I never remove that when i service a ETA movement . But have occasionally changed them when they have been damaged.  Looking good your watch  with the crown.

      FHF70 balance jewels settings

      By Bonefixer · Posted

      Latest project was a non-running ebay purchase with an FHF70 movement. I stripped and cleaned it, reassembled it, and got it running. So far so good, nothing damaged AFAIK.  I was oiling the top jewel on the balance (the one in the cock) which was a slightly unusual shock setting. I removed the spring (3 leaves) which was part of a chaton holding the cap jewel. This left the hole jewel behind which I retrieved with rodico and then lost it. I was taking it off the rodico, very gently as I thought, with tweezers, and then it just disappeared.  Fast forward a week, I got a donor movement, non-running, with the plan to just take the shock jewel that I’d lost. It was the same movement but had standard incabloc settings, and was steel rather than copper/brass.  I changed the cock and balance complete and it ran, not very well. I switched the lower jewel setting, cleaned and oiled both jewels and the replacement balance. Without the pallet fork the balance swings very nicely with a puff of air. With the fork in place, balance out, it flicks side to side nicely with power in the mainspring.  Put them together and it doesn’t run. The impulse jewel sits in the fork and it stops.      Any suggestions how I proceed? In case you didn’t follow that I have 2 FHF70 movements, nothing broken as far as I can tell, but mixing up the balance wheels and jewel settings results in a non runner.

      Oh and this almost perfect third wheel pivot and slightly set mainspring  Ah ok yes i see what you mean, good idea. I'll try that if i fluff this one up. The image isn't great quality but i like the idea though.

      Why cut the paper, cut a square around the image and grind to it.

      I did try that last time Rich , i traced the image from the Bestfit book which is the actual size. But its more difficut to cut the shape from paper than it is to grind the steel to shape. This way is pretty easy and the final shaping is done when fitting the part. There are a couple of things i will do differently next time, clamping the 2 pieces together with a drill press will help to hold while scribing the shape in. This was a bit tricky having only one hole, if using the pins and cork the drill size needs to match the pin diameter so there is no movement at all from the template. This movement hasn't finished frying me yet, damaged thread in the plate crown wheel hole and two rubbed in cracked jewels, thats gonna be much more fun.
