marcl Posted February 24, 2011 Report Share Posted February 24, 2011 I didn't need to but that's no guarantee... I've just ordered the 5512 and 1680 from josh. I'm going to mod them as cheap as possible. So I was looking at a way to make the crown smaller without changing it. I thought if I shave the inside of the crown and then re-shape it (round it off back to the way it should look) Then take a little off the tube. Would this work, or am I being stupid? Kind regards, Marc. Quote Link to comment Share on other sites More sharing options...
jmb Posted February 24, 2011 Author Report Share Posted February 24, 2011 That's what I did to this one except I did it in the lathe. You might be able to chuck the crown in an electric drill then put a file to it while it's spinning... Quote Link to comment Share on other sites More sharing options...

You might be able to chuck the crown in an electric drill then put a file to it while it's spinning... Well what I was thinking is holding it in some pliers, the crown may even fit in the teeth of them. Bit of masking tape to protect them, and the grind it on a fine grinding wheel. and finishing by hand with a polishing stone. But the chuck idea is a good one. So it worked for you? and you didn't have to shorten the stem? The reason I ask is I have never modded a watch ever! But I'm not daft I know I can do it, if it is possible. Thanks for your replies they are much appreciated, Marc. Quote Link to comment Share on other sites More sharing options...
Robaer Posted February 25, 2011 Report Share Posted February 25, 2011 Do you know if it's possible to fit a gen bezel on the retaining ring? Quote Link to comment Share on other sites More sharing options...
mir36 Posted February 25, 2011 Report Share Posted February 25, 2011 JMB, Did you get a chance to measure the diameter of the cartel dial? I don't have a case opener, but have estimated the dial of my Joshua 5513 to be 27mm. Is that correct? Quote Link to comment Share on other sites More sharing options...

Hi check out my post (5513 project almost finished) i have trimmed up the crown without shortening it by grinding it at an angle at both ends to make it appear slimmer it was put in a watchmakers lathe Quote Link to comment Share on other sites More sharing options...

Is it not possible to shave the crown and shorten it, as JBM has done above? Would this not work better for you? As you are almost there. I don't think I would put a new crown on then. Great post by the way, Well done with the watch it does look superb! Marc. Quote Link to comment Share on other sites More sharing options...

Hi Marcl Thanks for compliments yes it can be shortened this will require shortening the tube too and the stem which needs someone who has don this type of work before although i read someone somewere who shortened only the crown an tube aero! i am planning another build for a 5513 but with a tall tropic crystal so this will be fitted with a yuki 7mm crown and tube 60usd i think this is a good price for a crown not sure about the stem though!
