Any advice out there for cleaning/polishing watch crystal glass?
I know there are videos upon videos on howto clean acrylic watch crystal glass using toothpaste, Cape Cod cloths, an old toothbrush, etc.
However, I am trying to get a number of scratches out of a watch crystal I have taken the movement out of. It is for me a "tester".
I am fairly sure that this "tester" watch crystal is glass.
I have sandpaper (wet/dry) and I have a Cape Cod cloth which I have just started using.
I think you can see the scratches in question in the pics.
So, what I have done so far is use 400-grit sandpaper to scrub across the grain of the scratches. I have also tried scrubbing in a circular motion.
Maybe I am just not very persistent at this. I scrubbed for some time. But all I can see is that NOTHING is disappearing, and the only thing that IS happening is that now the whole glass is covered in a new set of sandpaper-made marks.
Maybe I can use the Cape Cod cloth to get these out. Maybe I can use the other 1500-grit sandpaper to smooth things out too.
This process looks so easy in the various Youtube videos. yes, I know these things can take time, but HOW LONG?? This is NOT one of the fun sides of watch repair that I am looking forward to doing now or, in fact, any time.
I really thought that it would be the case that - scratches and marks on the crystal? No problem! I can get them out! :)
But perhaps I was naive (?)
How long should I be scrubbing with the sandpaper? Is 400-grit not enough? Should I get more coarse sandpaper?
Hi everyone. Some vintage oris stop running not long after cleaned, I am sure the problem is common with vintage oris 677 kif and 704 kif.since I got many of them. I think of worn down staffs or weak main spring as the cause.
Interestingly dropping one drop of aircraft fuel on top of the upper and lower jewels of balance wheel only and it fly like combat jet.
Lots of hope to recieve your opinion.
Just got this watch in today and was polishing the crystal when it popped out! Have looked everywhere and cannot find out how to get it back on! Is it a snap-in? Glue-on? Need help!!! It is an acrylic crystal, btw. Please and thank you!
I’m looking at replacing the glass on one of my watches. It’s high domed acrylic.
Im browsing on cousinsuk and they list two different Sternkreuz High Domed glass. With step and without step.
Im just wondering what the difference is, as I can’t find anything online about them.
Hello, quick question in regards to replacement watch glass.
I’ve brought a Seiko 5 and the watch glass is 1.7mm thick. I’m looking at replacing this with a sapphire crystal (for no particular reason if I’m honest, the previrus owner had it swapped with acrylic and despite this it isn’t badly scratched), I can’t however find a sapphire crystal listed as 1.7mm.
I can however find 1.5 and 2.0mm. Would either of these be suitable?
Even if I look on cousinsuk the mineral glass isn’t listed in 1.7.
Any advice and guidance would be appreciated.
I just rebuilt a 7002A this weekend. I was very careful with cleaning/oiling, fitted a new mainspring and used a few dots of 8213 on the barrel.
The gear train, balance are as free as they could be - amplitude about 235 deg DU/DD.
Seems about typical for the few Seiko's I have. I know they have low amplitudes, so I'm happy as it is.
I tend to just use my "metric calibrated eye", and of course files/fine grit paper.
You can use one of these, If your eye requires a little more precise calibration.
They do work, but you will still end up finishing by hand/eye with good magnification, and obviously they only work with straight blades, so not much use for drill sharpening or cross headed drivers.
