Mike, in my book, Watchmaker is as Watchmaker does. Not sayin' formal trainin' ain't important, but this is a great poster child for the school of Self-Taught! FWIW and AFAIC, you're a watchmaker! Thanks so much for all the effort that went into this, and thanks again for the generosity of sharing it! (Sure hope Poly actually pulled her weight in this!)
I am still looking for the movement holder (extremely rare to find) meanwhile I use your method with a spare case....
Do you think it is possible to realise the movement holder copying the original one in wood?
Only had my 6138-8030 and this guide has already helped!
Thank you Polly!!!
I received my 6138-8030 yesterday and noticed a couple issues straight away.
Firstly, the second hand would not make it all the way around the dial. I found that the inner seconds bezel was loose from the dial and the second hand was being stopped by it.
Next, there was a fleck of dried glue floating around under the crystal.
I decided to disassemble up to the point where I could clean the dial and reattach the inner bezel. Once apart and both tasks completed, I attempted to reinstall the winding stem/crown, but no amount of fiddling seemed to work. Researching, I found this guide and the instruction: "To fix this problem you will need to insert the stem at an angle to push into the end of the clutch (not enter its hole) this will then drag the yoke from under the setting lever and allow the setting pin to re-enter the stems setting groove."
This worked and the rest of the reassembly proceeded unhindered.
The wound watch has kept good time for the last 24hrs but I have yet to put it on the timegrapher.
Overall I am impressed and excited about the quality of my first Japanese 1970s chronograph and looking forward to collecting and working on more.
