  1. 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?
  2. Working on a nice little Certina with square shape, and wounder where to get a new glass?? Somebody that have some leads??
  3. 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. Many Thanks
  4. 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.
  5. Cheers everybody! In the lately I have done service on vintage Certina and Omega watches from the 50 and 60 s. And I see that many of this have an metal ring atteched to the glass or crystal. Can somebody tell me the purpose of this? What is it for? Thanks and best...
  6. Hello - searched the forum a bit for a resource for choosing a replacement glass - see my Ebay find attached. The Swiss department store house brand "Mirexal" has no info that I can chase down on Google, so I went through the Sternkreuz catalog and came up with a couple options. Based on measuring the existing glass, and looking at the tension ring mounting arrangement (see sketch), and the approximate profile, I found these be an approximate match for OD, ID (on the tension ring, which sits ON the dial face), and inner dome height for hands clearance: - Mikado 4G 3009 - SK# XAC 300.615 - Seiko - SK# XAC 301.621 - Seiko - SK# XAC 301.640 Only one is stocked on Cousins, although the Mikado can be ordered. And if I order a 30.1mm crystal with tension ring, and the ID of the case measures 30.0mm, will I struggle with pressing the crystal into place? Seems like a lot of interference to me. This feels like a lot of guessing and approximations. Is there an alternate approach? PS - under that cracked crystal was a near-mint, lovely blue dial and an ETA 2789 movement in great shape. Until i pinged the Date Jumper Spring into the ether a while ago...
  7. Hello, I need some help sourcing the correct glass for this Omega Seamaster DeVille. Sadly the original piece fell off but, some pieces of the original glass (plastic) are still stuck in the bezel. how do I remove them and where can I find a fitting replacement? http://imgur.com/a/jzX2C
  8. Hello all, over the past 3 years, with Mark's videos as inspiration I have managed to save several watches from the bedroom drawer to being worn by their owners. Nearly all have benefitted by fitting a new crystal. No problem with a named watch ( like say a Tissot Seastar 7) but not so easy for a 1900's pocket watch, or an obsolete watch with no spares support. Since this is a topic which concerns nearly all of us, is their a guide to crystal selection particularly detailing the type of edge required to fit the bezel/case/tension ring and the use or not of cement to secure the crystal, the choice between acrylic or glass, hi/low dome, thickness etc?
