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?
