So, saw a video about doing this awhile back, watched it again, decided to try it on some buttons....
Copper plated buttons! Super easy to do, I can try to answer questions if you have any.
Should maybe clear coat them, but I think this will be one of those subtle touches to make a watch pop! Haven't placed them in a 6900 yet but that's mainly because the one I would do it on is downstairs XD
Let me know what you guys think!
