I am very nearsighted (between -6 and -7 in both eyes). With astigmatism. Now, in my late 50's I also have significant nearsightedness.
I thought a flip up visor - which I could wear with my glasses would be best. I purchased an OptiVisor with a flip-down loupe. But not happy at all with the visual quality.
I know you get what you pay for in optics. What is the best type of device for someone with old-bad eyes.
I have never used a regular loupe - but thinking that may be the way to go. Any of you guys (or gals) have a reccomendation?

I have an acquaintance who is closing his shop due to health after 43 years. He has a large quantity of parts, stems, crowns, crystals and all the paraphernalia one would accumulate after a long period in the business. He needs to liquidate his shop. This isn't a "Hey do you have a __ for a __." kind of post. We're talking serious stuff here. Mass quantities. If you need parts, equipment, etc. for your practice, please let me know. I will pass along his email contact to you. Obviously, this is useful primarily only to those in the U.S. due to shipping costs. But he has a huge amount of useful goods and is 100 miles South of Atlanta. PM me if you need something.
I'm having some unexpected behaviour from a eta 7750 that I'm trying to regulate after servicing.
I went through service procedure using correct lubricants.
Everything went fine. Actually I have some doubt on lubrication of incabloc wich I'm not sure I did correctly since I'm afraid that too much oil was placed in one of the two stones.
The fact is that when I finished I wasn't brave enough to clean and lubricate it again ... shame on me but I felt that task to be very very difficult.
Anyway after reassembling the watch I had it at my wrist for a week and it showed a great consistency at -10 sec a day.
It'a stop grade movement and resting at night in DU, DD 9UP and 3UP positions always showed something between -14 -6
I was very happy with that result and I thought that a little regulation would have brought it to a very fine time keeping.
Then I reopened the caseback and slightly moved etachron arm, that was resting in a nearly neutral position, in the + direction.
Nothing happened (measuring with timegrapher open source app)
Did it again, another slight push.
? ok I must have gone the wrong direction, then pushed all the way toward -
Ok this is annoying, all the way toward +
here I am,
what I'm I missing?
How come moving the regulator arm from - to + does not make any variation?

With the pallets removed, does the train feel like it’s running freely? And how about as you increase the winding power? If the power delivery looks respectable, then I’d check for something else obvious like mis-locking. How do you adjust the banking pins in terms of their orientation? I knocked up this crude little brass tool recently for correcting some banking pins on a JLC. It’s easier with modern movements are you are more or less just uprighting them.
I have used DX for keyless work for several years, since Mark recommended it :
You have a gem there! That Wittnauer is really a lovely piece, and I like the transistor symbol on the dial. Reminds me of when I was a kid in the sixties, and having a “transistor radio” was a Cool Thing. I see that the drive mechanism is very similar to the Luch electromechanicals. On a related note, one of my Luch watches is engraved on the back too... in Russian, so I have no idea what it says; but yeah, every one of our watches has a story. Cheers, Gryf
