.. that you talk about thinking of the pair :
I also have been looking " non-stressed" for a sample with the 2 dials, such
as yours, but I haven't near seen any having the dial & condition, like ours two..
Also, I 'm always a bit concerned, in case they would need a service (?).,,
But also: " Don't fix, what ain't be broken... "
I'm always amazed, how far & innovative JLC was / is (?) , even if it costs them,
rather then earns them . - I would expect, these days are over nowadays..
Best, also for your week
