Hi yes it's close. When I did my first crystal, I used a 5 dollar set of diamond files with water and it worked well. Just keep checking because you can get carried away and also file edges as vertical as you can. Once you have got it down to size just use Hypo cement to glue the crystal in place and your done. You can do this with just about any watch once you get the hang of it.
I tried to say Hello on the page with everyone else's greetings but couldn't figure out how to create it there. This is probably incorrect, but regardless Greetings to Everyone. I'll be looking for info on what kinds of things I can do to get a Timex Carriage watch to run. I put in a new battery, it has never been wet, and it's always been kept clean. It's got such a nice face with easy to read numbers and good band that I hate to let it go. I only had it a few years and it stopped running.
