I recently acquired this watch. I successfully replaced the battery, but I would like to replace the badly scratched plastic crystal, and maybe the bezel. Also, the setting stem seems tight to adjust. I'd appreciate any and all suggestions. I have a basic set of watch repair tools, and am quite handy. Thanks.

For info, fine sanding sticks such as the ones below, in the high grit grades, are excellent for restoring plastic crystals (and some metal casings).

I start at 1000 grade on a crystal that has bad scratches, or probably 3000 for one that is just fuzzed with wear, then work up to at least 7000, working slightly more around the curved edge with each increasingly fine grade, so as not to leave scratches or flats/facets from only working on the main face area.

Some Polywatch or Brasso etc. after that gets it back to a perfect shine.

I find working up to 1200 grit wet and dry works fine and finish with Brasso. As long as you are light with the wet and dry and let the paper do the work, rather any real pressure put on the crystal. Here's a before and after of this Rolex acrylic crystal I polished this week just using 1200 grit and then Brasso. Circular motion of the lint free pad or bud you use.

I think the quality of the acrylic makes a difference. Some crystals won't polish well just using 1200 and Brasso and need higher grit count pastes before the Brasso

Personally, I think Polywatch for what it is, is a stupid amount of money for a small amount of abrasive that's very watered down if you compare it to diamond pastes.

    • 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
    • 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.
