I got bored and decided to Hydro my DB-36 with some olive oil. I was going to order an F-91W, but then remembered I had the DB-36 just lying there. I've had the watch for roughly 9 yrs, so I figured, why not? I managed to get one tiny bubble that I was able to hide by gently flicking the face a few times. So I guess I have a 1000M diver now (jk). I know it's nothing groundbreaking or new to WUS, but just wanted to share.
