I have a Deep Blue Aqua Pro dive watch and it needed a new battery. Opened it up and replaced the battery but then it stopped again. I thought the battery was maybe questionable so I bought another and swapped it out. Now the watch stops intermittently and can be started again by pulling out crown, moving hands and pushing it back in. This will run for a short time.

I guess there is some dirt/something in mechanism and best course is to replace movement. Is that the case?

Here is a link of the watch I have.

Thanks for any help, Andy
