Hi, I hope you all are fine Those days I found an old omega f300 cone case sleeping on the drawer polished as a mirror when I bough it, many years ago cheap as scrap. I decided to give it a try and among other tasks, rescue it's finish, and discovered that it's impossible to do it by hand, each run marks his scratches in a different direction giving even worse impression than mirror polish, so decided to take the challenge of scratching it in a radial and homogeneous pattern. I read somewhere a post about redoing an Omega cone surface, and found it really difficult, doing supports, regulators and so on, and requiring even a grinding machine, impossible and not to inspiring for me. Saw even someone using a dremel that took the hell out of me. Below it's the simple contraption that allowed to do it, maybe you can find it useful for your projects, it's cheap, easy to build and makes the redo a piece of cake. All the secret is to guarantee that sanding paper (or whatever you use) attacks the surface always in the same "radial" direction, this is impossible if you grab the case or sand paper by hand, any minor deviation will shine as a photo flash ruining the look. So to do it you may elaborate a complex rotating support, or take a simpler approach. As the watch is round, almost any "support" that "fills" the case will allow to rotate it around that position keeping the angle and relative position of the case. So with just a few sticks laying around I've been able to "build" a really simple "fill" to firmly support the case in a fixed position, allowing it to rotate freely but preventing any displacement up down, right or left, so keeping the case in the same relative angle no matter how much you rotate it. The second challenge was to make a sanding "device" to scratch the cone wall without any lateral displacement, so, just up and down motion along the cone wall, with any lateral distraction. Again an old lumber piece and a single carpenter clamp did the trick. Below are a few photos of the job, cheap, easy and efficient, I hope you find it useful. It was fun to repair a watch case with lumber, sand paper and carpenter tools, still thinking what use give to the hammer. My apologies, but don't know how to lay the photos in their place Ask if any doubt. Cheers and take care Ricardo

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?

Hello! So I cleaned the clock parts in naphta and IPA. I put the wheels in a drill machine ('cause I don't have a lathe) and I polished the pivots (they are so clean and shiny now). How do I polish the bearings (the holes in the plates)? I'm thinking at puting some polish compound on a toothpick in the drill machine and presenting the bearings to it. Bogdan

I am wondering if anyone could provide some advice on polishing the scratches off steel watch case and bracelets? Would love to hear how you could do it, both for polished steel and also matte/satin finish steel. Thanks Ferdinand
