archibald Posted July 19, 2007 Report Share Posted July 19, 2007 Assuming the crown or stem can be modified to make an OEM crown work w/ the handwind movement, it looks like the tube will be the next hurdle if anyone would like to use the crown w/ a Jimmy case. The hole in the case is 3.25mm and the crown needs a tube with an inside diameter of 2.3mm-2.5mm. Of course, the length of the tube can be customized. My own search of the usual places has come up w/ no ready made solutions. Since I have this exact combo of crown and case in hand at the moment I thought I would submit the dilemma to our RWG brain trust for ponderance.

launchjack Posted July 21, 2007 Report Share Posted July 21, 2007 You may want to get a hole gage/mic to confirm your measurements. The last time I made a tube for a JZFu, I had a little different number. Good Luck" Link to comment Share on other sites More sharing options...
archibald Posted August 14, 2007 Author Report Share Posted August 14, 2007 I'm happy to report that this can be done. Custom-made 316 SS tube to fit Jimmy case, custom-made .9 OEM crown/1.2 stem combo. Works w/ Jimmy CG as well. Link to comment Share on other sites More sharing options...

The crown tube I have from Jimmy fits the OEM crown perfectly. I haven't tried to fit it to my 029 case yet, but I am sure that is easier than trying to get a crown to fit a tube.

My watchsmith's opinion on the Jimmy tube is that it's pretty close, but probably won't form a water-tight seal or activate the spring mechanism properly w/ the .9mm OEM crown. @kruzer: I think I hear a lathe turning as I type this...

Watchmeister Posted August 15, 2007 Report Share Posted August 15, 2007 Yahoo! Looks much better than I could have hoped. They will be true works of art. You have to take a group shot. It will be one for the ages. Link to comment Share on other sites More sharing options...

Excellent ...sounds a bit lame ...but this is like the decoding of Egyptian heiroglyphs when they found the Rosetta stone.... A great puzzle solved I think...?:-) Awesome contribution to the craft IMHO Thanks FGD Link to comment Share on other sites More sharing options...
