Hah... Reminds me of one of the first watches I bought.
It was a v5 PO and when I finally received it I attempted to grease the caseback and crown. Next thing I knew, I had pushed too hard and my keyless needed to be reset. Off to the watchsmith...
It came back and I wasn't happy with the time it was keeping so I attempted to self regulate it. Well, I pushed too hard on the two piece regulator and the balance spring unravelled. Off to the watchsmith...
See a pattern?
I finally replaced the movement with a swiss 2824 as well as the full franken monty and used the old asian 2824 as a test movement to learn the skills needed to mod my own watches.
In any case, while it sucked and almost put a stop to the enjoyment of this hobby, it ultimately pushed me further into it. I've since gotten the proper tools and been able to replace completely break down and oil a movement. The right tools definitely make the difference between a good job and an 'alright' job.
Good luck and if you don't have the tools, I'd suggest sending the watch to a watchsmith to get the keyless fixed rather than cause more harm.
