jackt Posted March 14, 2022 Report Share Posted March 14, 2022 Hi, I have a scratch about 5mm long which I can feel with my fingernail. Local watchmaker says he cant polish it out cos its too deep. I mentioned about him fitting a new crystal but he wasnt interested. I have used Polywatch, Cape Cod, Vim, car paint scratch remover and toothpaste which have reduced the scratch but not removed it. I wonder whether wet and dry 1000 grade might remove the scratch and then I can polish off with Polywatch. I would very much appreciate advice please. TIA.

oldtools Posted March 14, 2022 Report Share Posted March 14, 2022 Is the crystal acrylic? Mineral glass? Sapphire? Quote Link to comment Share on other sites More sharing options...
jackt Posted March 14, 2022 Author Report Share Posted March 14, 2022 Hi oldtools, thanks for coming back so quickly. I dont know which crystal I have other than nothing used thus far will shift the scratch. I think it must be the hardest crystal. Quote Link to comment Share on other sites More sharing options...
Nanuq Posted March 14, 2022 Report Share Posted March 14, 2022 Give it the old tap test. Tap tap tap .... does it sound like glass or plastic? Quote Link to comment Share on other sites More sharing options...
kernow Posted March 14, 2022 Report Share Posted March 14, 2022 If it’s glass and is scratched, it’s most likely mineral glass. To tell mineral glass vs crystal glass: place a drop of water on the glass. If it stays as a bead it’s crystal. If it spreads out into a pool, then it’s mineral.

jackt Posted March 14, 2022 Author Report Share Posted March 14, 2022 Hi Guys, We learn something every day. The bead of water spead as soon as it hit the crystal and the tap test is plastic and not glass. Given that what might I use to remove the scratch.Thanks again. jack Quote Link to comment Share on other sites More sharing options...
Nanuq Posted March 16, 2022 Report Share Posted March 16, 2022 Try Flitz metal polishing paste. It's messy and you'll wear the skin off your thumbs, but it should do the trick. Quote Link to comment Share on other sites More sharing options...
Timelord Posted March 16, 2022 Report Share Posted March 16, 2022 I would not lose sleep over this! I would just reduce the scratch depth as best as possible and live with it! Being an acrylic crystal, you are going to acquire many more scratches unless you are going to wear it with your hand over your head or leave it in the glass cabinet to stare at! One of the many disadvantages of these plastic crystals. Jusf bear in mindthat the more material you shave off, the weaker it gets as it is only plastic! I use a very thin drop of Brasso after using ,2000 grit sandpaper. Just enjoy it!! Quote Link to comment Share on other sites More sharing options...
jackt Posted March 16, 2022 Author Report Share Posted March 16, 2022 Hi guys, Many thanks for the info and advice. In trying to improve the look of the watch I have made it worse. I am sure that the crystal is not the original cos the dome is a lot lower than identical models I have seen. Who ever fitted the crystal did not sit it firmly around the dial cos some of the paste has got under the masking tape and under the edge of the crystal. I now have white paste inside the edge of the crystal. Only thing now is to find a watchmaker who will fit a new crystal and clean the edge of the dial. Isnt hindsight a wonderful thing as I could have got a new crystal fitted in the first place. Still gaind experience in polishing crystals. Thanks again for all your help, this really is a great forum. Quote Link to comment Share on other sites More sharing options...
oldtools Posted March 17, 2022 Report Share Posted March 17, 2022 Here is a list of people on RWG that may be able to replace your crystal. https://rwg.cc/forum/179-repairmodification-services/ Quote Link to comment Share on other sites More sharing options...
jackt Posted March 17, 2022 Author Report Share Posted March 17, 2022 Hi oldtools, I am most grateful to you for that list and appreciate your time and trouble. Looking at the list it seems the guys are in the US and Canada. I am in spain so postage and import duty would be expensive. I should be able to find a watchmaker in one of the main towns. Thank you again for all your help, regards jack Quote Link to comment Share on other sites More sharing options...
SSTEEL Posted March 31, 2022 Report Share Posted March 31, 2022 Try polywatch and cotton wool.Sent from my Nokia 9 using Tapatalk Quote Link to comment Share on other sites More sharing options...
jackt Posted March 31, 2022 Author Report Share Posted March 31, 2022 Hi SSTEEL, Thanks for that. I tried wet & dry. polywatch, car paint scratch remover, tooth paste and eventually found a watchmaker who is making a new mineral crystal for €25.00. jack Quote Link to comment Share on other sites More sharing options...
