Thanks for the advice. I was worried about the film. I found the isopropyl left some white residue on the parts. Which is why I moved to acetone, but I can't wash pallets or the balance for too long in it. I also have petroleum ether 80-100.
Would you be able to recommend a product for me to try? I've never tried one of the ammoniated cleaning products. I could get some of the L&r fluid.
Epilame is good. How you distribute oil on the escapement is a matter of dispute but get your lube on there and then gove it a day. You'll be surprised. I epilame every freakin escapement that comes through. Don't epilame the fork horns or pivots. Your cleaning procedure is probably lacking. There are pro chemicals out there for a reason. The slightest film of whatever can drag you down. There are threads upon threads here on the subject. But most of all, if you are taking care like you say, is let it run. You'll probably find it picks up 20- 30 degrees of amplitude.
Just to clarify, I wasn't aware that the day function did not work. So when I asked for a new crown and stem that is all what was replaced. I can set the day no problem but it does not advance to the next day 24 hrs later. Only the date works.
As for the crystal, now I could be wrong here but it seems to be a press fit. And that it does not require glueing. I polished the inside so it's like new and then it pressed back into position. I'll have to see how much it will be for the day function to be fixed. It wasn't a service as such just a replacement stem and crown.
Yep I will go at it again tomorrow. Most of these movements are already running around 250-260 amplitude some greater like this one. So I'm thinking maybe I can't expect them to perform much better due to the quality of them? Should I use the same benchmarks for a chinese clone as a Swiss made movement I.e 270 minimum dial up and down? Something is not right with this one though as I havent applied lubrication and there's an amplitude drop.
