Hi thanks for the great video i had condensation on my glass in order to get to it I had to remove the rotary and now the rotary is not working is there a trick you can show or tell. Thanks again very grateful

[@SolimBD]

Thanks for comments

[@PraXii1109]

lot of people are having a problem of rotatory crown not working after re-assembly, ive found the problem, its actually the reinsertion process of the switch, if the tip breaks due to a very minute Mal-alignment, the rotatory switch is useless after that, and only option is to replace it. same happened with me, u actually need to mark its correct alignment with the body before removing it. otherwise it will break upon reinsertion.

[@theabelsfam457]

is that a water? where you soak the green part?

I notice on this video that the rotary switch does not working after you put all the parts back on its place. How's the g-shock now? What action you did?

[@andesonmorais]

I had the same problem. I removed the rotary button and it stopped working after I put it back. I still haven't found any solution to this problem.

[@illmatiK4]

@@andesonmorais same here, I replaced the battery and now the rotary switch is useless. Haven’t seen any solutions either and it’s starting to irritate me.

after replacing the battery, you need to restart the mechanism, this can help you.

If you wash it easily, what do you use to soak the G-Shock watch movement in water? But if it's easy, uncle, it's easy to understand how to disassemble and assemble the ghost watch machine
