Ok so Christmas is done and the ZF was worn with pride! They really do look mint...
Anyhow, it's running like an absolute DOG. Losing about 2+ minutes every day (Maybe more as can't stand it so keep fixing the time).
This could be due to the lost jewel under the Date Finger as that will be causing undue friction now, or it could be another issue I am unaware of [...] which will mean I have to take the skills to ANOTHER level to clean some parts and oil? Or learn how to adjust the accuracy which without a time graph machine is impossible?
You're 90% of the way done. (Well it seems like it anyways) keep pushing, only new Zealanders would give up now.
This is entertaining keep going buddy!
You are doing so great, it's insane, and an encouragement for me to pursue my own endeavours to increase my skills.
As bad timekeeping can have several reasons, it would be interesting to know if you noticed the same BEFORE you started working on the watch, or if it is something that only occurred after that.
Lubrication does have a great effect, but still there are badly oiled watches directly from China, that run reasonably well. Adjusting the accuracy is not that hard and actually fun once you get into it. I have done that with good success, adjusting timekeeping and beat error. While the professional way would be to invest in a proper timegrapher, I have done so by the use of a fairly simple app on my smartphone until now. Of course the app is probably not THAT accurate, but still OK so far for me - and it's for free!
Ok good to know and thanks for the encouragement! I’ll give it a red hot go! Will take like 3 weeks to get a new movement but as always will report back with photos and progress.
I bought Kello, which I guess I could try to use. Be good to know how to modify the watch speed though. If anyone has any good links to YouTube’s that they like feel free to post!
Here you go mate - hope you find it as useful as I did (and I hope the link works)

Ok so I've ordered the $125AUD total 3135 movement, so at least I will have a lot of parts as needed...
Next I am thinking about the cheapest Timegrapher that will do the job... Is a Weishi 1000 ok??? This one looks good for the price ($133AUD currently)
What's the difference between a 1,000, 1,900, 3,000 or 5,000? Are there any brands better than the others? Can anyone make any recommendations for the rabbit hole?
The 1000 and 1900 have a cord switch that’s very inconveniently located behind the machine. The 1900 however can stay in standby mode so you don’t need to hunt for the switch with each use. It also has a higher resolution display that better than the 1000 model.
Ok so a small update but so many questions.
Got the replacement movement from AliExpress, seems ok so far. Haven’t had the energy to pull apart the Sub and try to fix yet.
The main issue I have right now is that the Sub is running like a dog. It is now running about 1 minute slow per 3hrs and when I take it off my wrist when it’s fully wound it will stop working within about 4-9hrs at most. So something is very wrong.
My initial hypothesis is that when I did all the messing around with the date wheel and soldered it’s now rough and maybe even a bit bent. Plus the gem/crystal whatever you call them is also gone so that would be definitely creating drag.
I’ve also had it apart four or five times. Unsure if I need to oil anything? I have the oil now but have been reluctant!
Thoughts welcomed before I pull her apart and go again!
Bro at your experience level I highly recommend doing a complete movement swap to the new movement and get your watch up and running well again.
Then you can leisurely tinker with your problem movement separately and gain experience tearing it down and learning how to service it properly. Get the service manual, get all the proper oils and oilers and some more good tools, etc.
It is not good sense to ruin a good movement to try to salvage a bad one. You may end up with two bad ones.
The issue is that the movement I got from AliExpress is a “cheap” one. It was $125 which isn’t terrible but it’s not the best and I assume it’s nowhere near the quality of the original that is in my watch currently. All I wanted to do was replace the datewheel and gem from the AliExpress one to the one in my watch and see how she runs.
