Doxa dive watches are notorious for losing the paint in their bezel numerals. So I got really good at doing them. Get some Testors black hobby paint in the little bitty glass bottle. Wipe the bezel with rubbing alcohol to get it squeaky clean. When it's thoroughly dry, paint all the numbers. I used a small tip $.79 brush from the hobby shop. Be sloppy, it's okay. Let it dry *completely* like overnight. Next day get a wooden toothpick with a squared off end, or even a wooden chopstick from the grocery store deli, and rub the extra paint off the bezel from around the numbers. It comes right off. Easy squeasy, do it with your eyes closed. I did the orange and the black on this one.
