I am on the watchuseek forum and recently came across a thread on a hydro mod done on a G-Shock watch. I have been looking into this and might try it out. It involves filling the watch with a oil to improve vision underwater and at severe angles. I ran across some pics of my series g-shock done and it looks amazing. I also saw it done on a Citizen Orca. Has anyone else looked into this or modded your own watch? What are your thoughts on this?
