To date, what is the most difficult and frustrating watch movement that you have had to reassemble?
Personally, my choice (So far) would be the Harley Ronda 726 chronograph.
After stripping, cleaning, and reassembly, I discovered that the circuit was faulty and was in need of replacement.
Luckily, I found one in Los Angeles USA.
The circuit is buried deep inside, so a couple of layers have to be removed in order
to get at it.
Lining everything up, after, is where the nightmare begins.
Honestly, what a totally frustrating experience and how these things are ever designed and made in the first instance, is way beyond me!
A beautiful watch, though, and the rewards after competion make the effort well worth it.
Well, over to you, what is your nightmare?
Here are the timegrapher readings for dial down (181)and up (280) Same lubrication as before I haven't cleaned it yet. Something very bad is happening when dial down. I have not seen a difference so big in these two positions before. I moved the beat corrector all the way over as well. The watch is also stopping when turned dial down. I can start it again by hacking the balance and pushing the crown back in (sometimes) . Any suggestions? I don't think this watches issues are related to lubrication but what are your thoughts I might be wrong.
After a few nights including the last one which ended at 5 am this morning I kind of restored a watch "crystal" cutter. There are still two things I need to sort out. 1., I lost a hex nut. I remember when I cleaned it but it disappeared, have to find it or replace it. 2., I learnt that there is imperial system in the UK the hard way, did not measure even once and tried to refresh a tread with metric....ohh dear. Now I have to source an imperial tap and die set.
What I would like to ask:
- Does it need some kind of calibration? How to do that?
- Where to source the sheets so I could try to cut out a watch "crystal"? What is the material I have to get?
- I was told that the cut needs to be in an certain angle otherwise the crystal would not stay in its place, but I cannot see how could that be achieved with this tool.
- I was also told and read that I need a glass press set to make the "crystals" domed. Could anyone educate me?
To my horror there is no youtube video I could watch???!! How is that even possible?
I understand that now you can buy watch glasses for peanuts but again here I have this for my amusement.
