I have not filmed this one , I was going to do the disassembly but figured I need to get my head down and learn the movement first before bringing it to YouTube |

This is a 1969 proof version so very early model Same as on my 6139-6020 Pulsations, bought in Hong Kong by my late father-in-law. If you want to swap it out for a Spanish one I’m all ears... |

Good work Mike. Decent results on reassembly I assume? Or did you just sell the oil to your local chippy?
🤣

Nice one Mike. That's a whole load of oil, but at least it doesn't look like it has congealed.

Nice one Mike. That's a whole load of oil, but at least it doesn't look like it has congealed. Hello my friend ! Yes it was all washed in the ultrasonic using dish soap and water first just to get the oils off. Then about an hour of spinning in all the solutions in the watch cleaning machine . Tomorrow night I will inspect and see how clean everything is before starting the assembly. I am confident enough of reassembly just need to read the manual well for the oiling and some setting procedure . I am told the 6139 is about the easiest chrono to do . |

Been cleaning the parts most of the night. As it’s my first I will be a bit nervous but mainly of fitting that chrono hand , however the donor is not red so I will have to paint it first... still to find suitable paint , red mat finish .. |

Although I haven't done many chronos, I would agree the 6139 is the easiest and most simple. I'm sure you will have little problem putting it back together again. When setting the hands, I remove the crystal and recase the movement with pushers and stem - this will allow you to hold the reset down whilst pressing in the second hand. I use watered down acrylic paint and gradually build up the colour. It is easy to apply and leaves a matt finish. Thinned Humbrol Matt enamel works well too but you will need to wait about a day to cure before pressing the hands. Looking forward to the end result. |

Great work Mike! I would love to see it on your channel so we can learn from you but I reconn it needs all of your attention being the first chrono. Hopefully there will be more in the future. Good luck!

So just bringing you all an update. The watch had a good clean and first of all I used a water and dish soap combo in my ultrasonic this was just to remove as much of the oil before putting it in the Brenray cleaning machine  As you can see it was quite the oil slick. It went into the Brenray for an hour. Two washes in L&R cleaner followed by a long rinse cycle.  All parts looked nice and clean under the microscope so now was the time for assembly. I had my print off of the 6139A service manual ready. I meticulously rebuild all the train oiling as perfect as I can under the scope. I oiled the chrono wheel but the part to press down and oil I found quite challenging as I was so scared to damage the wheel so I am am still unsure of how well I did this ( more on this later) It took probably 1-1/2 hours to build just the movement side as I was just taking my time and ensuring everything was perfect . It’s all far contrast from the 6309 in my recent video where it took me a timed 10 minutes to build a 6309 ! The final chrono bridge took some placing as it seemed the minute recording and intermediate wheel would not mesh properly. This could have been down to the hammer , I just don’t know but it eventually sat down properly. With some wind and the balance installed it span into action   I sat and watched it pleased with my first chrono accomplishment and poured a nice single malt  This was all short lived as the following morning the watch had stopped and as I had to go to work the agony of not being able to diagnose for the whole day was terrible. In return from work I pressed the chrono button and bam it span into life again ! I stop started it a few times and then checked the fly back button would work. It ran for hours so I regulated it. Quite pleased with how it looked with the chrono running .  However when I stoped the chrono wheel the amp dropped considerably ...  I can only conclude there is an issue with the clutch somewhere so will need to strip it, clean that part again probably now in the ultrasonic in Renata . I left it running overnight with the chrono function on and once again it stopped..... Damn . I brought it to work with me today and tried both on and off and it’s never stopped the whole time (typical) Clearly I have a few problems to overcome If the chrono wheel has had it then I will love with the low amp and just keep the chrono engaged. I change my watch every day as it is and this one is more about the accomplishment. I will however still want to fault finding. If anyone has some ideas please let me know Thanks |

I left it running overnight with the chrono function on and once again it stopped.... Really impressive first try Mike! You can try the eccentric screw for the coupling lever to bring it closer and therefore separate the clutch plates further. I would definitely try the Renata route and try oiling the pinion again. If you are cautious about the oiling procedure, I would use a pin vise to hold it upside down and over oil the pinion slightly and spin the wheel a few times. Clean up the extra oil. |

kue thanks , I was wondering about that eccentric screw could it be that it’s too tight on the clutch or opposite too loose. I used a Hole’d plate to put the chrono wheel in (like a staking plate) it’s how hard to push down I know this part is like unicorn poo so for me to break it would be devastating

Certainly could be too tight. Just a thought, did you hook the hammer click to the hammer? That can cause it to start stop as well. |

By hammer click do you mean the spring? If so yes. I will he dismantling again most likely so I can double check
