Mums glasses are scratched but the main problem is the foggy patch in front of both pupils.

Looks like the anti glare is failing.

Has anyone (from UK) had any success in remedying this?

I ask from UK as I have seen US products being used with success but I don't want to wait an age to order stuff.

Thanks.

You could try polywatch, cleans scratched acrylic crystals up a treat, but will probably remove the rest of the anti glare.

Losing the anti glare would not be the end of the world.

Just worried on what to use as I dont want to remove any of the actual lense thereby changing the optical properties.

The problem with polishing any lens is you do by the nature of it remove some of the lens. 

 

The worst part seems to be right in the line of sight  and must be irritating so It seems to me that your Mum is going to need new glasses anyway even if you don't try. 

 

Polywatch may very well work and in my experience does not take away too much plastic so I personally would have a go but take your time and check on the effects at short intervals - see what your Mum wants first though.

 

If they are reading glasses I would not be as worried but distance glasses may be a different ball game. 

 

Cheers,

These are just to watch TV with and as you rightly pointed out can't make them any worse than they are.

Gonna experiment with Polywatch tomorrow and as you suggest a minute at a time to check progress.

That is really odd, they must be really scratched.  I must admit I tend to chuck my reading glasses down onto the bench as I am working but that they should have the scratching at the precise focal point for her eyes is weird - try brasso or something with higher grit and finish off with polywatch perhaps.

Yeah was surprised myself. Maybe the seller filled the tube with moisturiser instead [emoji1]

I have liquid Brasso. Used it to clean tail lights before with great success.

If that doesnt work gonna immerse them in white vinegar for a while then use a plastic scraper.

      Tissot case back removal

      Here is a method described in the watch repair book of Mark W. Wiles. Don‘t hammer, just tap very gently!

      Alex mentions the coils below the stud should remain the same as you move the regulator block along the terminal curve.  Mine do that. What he doesn’t discuss and is used in the other video is how the regulator block is used to adjust rate and positional error.  He also doesn’t mention how opening and closing the pins could and in my case does, alter amplitude  In Alex’s video once he sets the stud he never adjusts the regulator pins yet every new movement I get have the pins signing closed.

      The video I linked above does mention the spacing of the hairspring coils, and the importance of the regulator being able to move through its full range without distorting the hairspring - the terminal curve of the hairspring must be concentric with the regulator pins throughout the regulator’s range.  If you meticulously follow every step in this video, the regulator system should behave as intended, regardless of the brand of the movement.  Best Regards, Mark

      Very Old Watch- "Echappement A Ancre", "13 Rubis" on the case

      By coreymsnow · Posted

      Hi friends! My mother got a bunch of old watches from a horologist who was retiring, and he subsequently passed away. It's been in her studio for years, and she showed it to me today and I just fell in love with it. Sadly, I don't know a darn thing about it yet. It's quite old, or at least seems to be. It has two winding arbors, but the key is missing. The crystal appears to be some kind of yellowed plastic, which is odd- I think it was replaced at some point to possibly protect it or something. If I had to guess, it's from the mid-19th century, given that it has no keyless works and that it says "Anchor Escapement" in French. It looks to be about 18 ligne, and the case fob is positioned in the upper right corner. The face is missing the dial, the hands, and a couple of the wheels that drive the hands- I think. But the movement itself seems to be in excellent shape. The serial number on the movement matches the number on the case- it's stamped on the movement and on the case in two places. I haven't started any disassembly yet, but I'm wondering if anyone can give me some idea of what kind of movement it is, and where I might look to see what parts are missing from the face. i may even have a dial that would fit it. It's in good enough shape that I think I could get it running, assuming I could find the missing parts. Any insights are vastly appreciated and thank you! Addendum: The inside of the case has some *very* tiny scratched numbers and letters in it, but I am having an extremely hard time seeing what they are. Like "N 99" and "No192X", They were clearly done with some kind of sharp stylus and maybe they mean when it was serviced or by who? Addendum the second: At least one of the scratches seems to say "N1921X" or maybe "W1921X". Serviced in 1921? And the inside lid of the case has the letters R H with a star between them, and a very tiny mark that says "ARGENT" in a u-shape.

      I’ve watched every video I can find on YouTube. Some of the info is contradictory and none mention  the effect on amplitude or spring coil spacing which I observed. I was hoping someone here is a Seiko expert and knows these inside out.
